This Extraordinary demonstration highlights the durability and efficiency of this high quality diamond core-bits called the FTJ “junior” range.
We made more than 60 consecutive holes! … And the core bit still has life in it to make many more… you can see at the end of the video that the bit is only slightly worn.
This incredible life expectancy is achieved because the core bit is made in the typical Montolit high quality way and ALSO because of careful use by the operator – so the instruction is:- Do not ‘force’ the cut – take your time – ‘feel’ the cut – relieve the pressure and keep the tip cool !
These great results are not a surprise but a confirmation, by demonstration, of the quality of this dry drilling tools which are used daily by professional tradesmen all around the world including tile layers, plumbers and other installers etc. when drilling materials such as porcelain and ceramic, tiles and granite.
We would like to inform you that the NEW Core Bit FAJ is now ready!
A WET USE small core bits useful for making small diameters holes in very hard materials like:
Gres Porcelain – Hard Ceramic – Granite – Marble
Advantages of these new core bits are the speed and the life, better than the standard core bits on the market. Especially about the life, if correctly used, it is possible to make a lot of holes, between five and ten times more holes compared with the similar core bits on the market.
Peculiarity of these products, they work very well also with few water, only wetting a little bit the tile and the tip.
IMPORTANT! You can use these core bits also with the cordless power tools (drills) by Bosch, Makita, Metabo, Hitachi etc………. (but note: minimum rpm 1000!)
Increasingly hard ceramic and porcelain tiles with uneven or irregular surfaces are definitely giving the tile layer a difficult time when cutting them into beautiful creative shapes and innovative patterns that are being demanded by the customer of today!!
These clients require such perfection in the finish that it is really difficult for the tile layer to achieve the desired effect without having a complicated array of specific tiling tools, plus a good deal of experience!!
For wet or dry cutting such hard tiles as these Montolit has created a new continuous rim diamond blade called Progres CG.
Thanks to the particular mixture of diamond and metal within the cutting crown, Montolit have developed such an innovative blade that the cutting operation is very fast and very precise in terms of aesthetics because the risk of chipping hard tiles has been greatly reduced.
Today the Montolit CG Diamond Blade represents the top of the range as regards diamond blades designed for cutting Gres Porcelain.
These blades are now readily available in 115 and 125 mm diameters.
Countless times you will need to cut a square hole in the lining of walls for such things as electrical panels, sockets and switch boxes in an effort to meet the ever increasing demand for more power points that feed telephones, satellite TV, computers, electrical appliances, house alarms etc !!
The Montolit R & D Department has developed a small diameter dry use diamond blade to enable the tradesman to do all of these jobs. The blade is 85mm diameter and fits to a normal angle grinder.
The name of this new blade is “SQUADRO”(art. TCS85)and it will allow you to cut square / rectangular and very small (4×4 cm) shapes in all types of ceramic, porcelain, marble tiles and granite materials.
Used with care, even on site, the “SQUADRO” blade will allow the user to produce precise and accurate square cuts suitable for small cover plates and switches etc.
It’s main characteristics and benefits are it’s extreme manoeuvrability, the speed of cut and the high level of finish. All achieved because of the Montolit high build quality and narrow blade width !!!!

The answer is yes!
There is now a new range of diamond blades known as DNA made by Montolit Spa.
These new DNA blades represent the most important innovation and genuine technological revolution in the field of
diamond tools since the introduction of laser welding in 1980.
This technological innovation consists of the controlled, three-dimensional mesh distribution of the
granules of diamond contained within the cutting edge of the tools. With this technology you can have a diamond disk that contains the exact number of diamonds needed,
and put in the best position for cutting a particular material.
The most common feedback that our customers give us is: “With these blades I was able to easily cut
even the most difficult materials that other diamond blades would not cut.”
Sometimes materials such as the last generation glazed porcelain and very hard thick tiles
with an uneven surface caused big problems where even the blade and the material was damaged during the cut.
Now these materials are no problem when using the latest generation Montolit DNA Blades!!
Moreover, DNA blades can last up to 50% more than blades made with traditional technology
and at the same time reduce the cutting time by at least 30%.
My advice is simply to ask those who used them!
Drilling a tile of any type is probably one of the most difficult operations to be undertaken by a tradesman.
The kitchen and bathroom are where most of the hole drilling in tiles is carried out since these are generally the areas where most water connections and fittings are required!
We should distinguish between the shape of the hole required.
Round holes allow the passage of pipes and cables, plus wall plugs for the screws which are used to mount the accessories. In these cases the hole size required could range from 5mm to 120mm! Square holes are necessary where sockets, junction boxes or cabinets of various sizes need to be fitted.
In the case of drilling round holes – this operation is usually easier to carry out and the Tiler may have many different makes of Drill or Core Bit at his disposal. With careful consideration to the type of tile to be drilled the drilling operation may often be carried out dry in a soft ceramic tile or in the case of a hard Porcelain or Granite Tile water should be used to keep the drill bit cool. These methods allow for precise drilling.
However a square hole requirement in a Tile can be a major dilemma for the Installer!
Cutting square holes can be achieved in two ways.
Firstly dry cutting, depending on the type of tile material, could be carried out with the aid of a special ultra thin 115mm diamond blade fitted in an angle grinder.
Secondly, again depending on the type of tile, wet plunge cutting is another option using an Electric Tile Sawand suitable wet use Diamond Blade.
Apart from plumbers, electricians and tilers having the necessary expertise and skill it is also important they are made aware that a square cut hole in any type of tile may increase the risk or chance of cracks emanating from the square point of the hole. These cracks may be induced because of the drying out process or settling of building or land.
If you or your tiler make the holes in tiles without a correct drill or drilling procedure (using for example the hammer more the normal drill bit or making a square hole) it is most likely that the finished job will fail as illustrated in the picture.
Failure (cracks) may occur after a period of time (days, weeks or months).
This problem has previously been explained on the Blog site: see Old and new ways to make holes in tiles. As you can understand, you will find the problem when the work is finished and when it will be impossible to make the claim and very expensive to fix the problem by laying new tiles. So, if you are an end users, ask to your layer to use core bits for making holes in tiles. With this diamond drills you will avoid many problems with cracks in your tiles.
To make a square cut out – suitable for a switch box etc. – using a grinder equipped with a diamond blade
• Advantages: you use only the grinder with a compatible tile cutting blade -this is quite fast operation
• Disadvantages: During grinding a soft tile may break quite easily (like our example in the video). Grinding may cause the structure of the tile to diminish allowing the tile to fail after fixing because hairline or invisible cracks were created during the grinding process. This can frequently happen where a tile will crack from a corner due to movement caused by building settlement.
To create some kind of irregular shaped pattern on the tile edge or a circular using the grinder and then a light hammer to tap out the centre etc. to complete the job.
• Advantages: you use only the grinder with a compatible tile cutting blade
• Disadvantages: creating irregular shapes and breaking out a circle – can be a slow process – also it is very easy to break the tile during the grinding operation
• Advantages: the hole has a good finish – the drilling operation is fast and easy – the structure of the tile is not diminished in any way making it very resistant to failure in the course of time.
• Disadvantages: you need the correct drill bit
In the video clip below, you can see an example of these three ways to make holes in tiles. Normally, holes in the tiles are required to connect sanitary wear, electric cables, special parts etc. In the fist part of the video we made holes in a soft glazed standard tile which broke easily. Drilling very hard and compact tiles such as Enduro by Marazzi was very easy. It was possible to make the three types of hole illustrated in the video.
*We mean new type of tiles because for old and soft tiles like bi-fired tiles it is possible to make holes with manual machines (tile drills – our art. 18 and 20)
How can I optimize the numbers of holes made with a FS Mondrillo core-bit?
Why does my Mondrillo core bit make not many holes? Once a while it happens that a clients asks this question to our technical dept.
The main reason is probably the fact that the instructions of use were not correctly followed. With this core-bit (dry use) it is necessary to drill the tile with a rotative movement during all the drilling operation.
Without this type of movement:
• The diamond is too stressed loosing definitely its cutting qualities.
• The dust doesn’t come out from the hole, covering and damaging the diamond tips.
The drilling tools performances indicated by Brevetti Montolit are variable because they change according to the type and thickness of the different materials:
• Increased thickness means lower performances
• Abrasive materials rich of quartz means lower performances
The hardest material on which the FS Mondrillo core bits has been tested is Gres Porcellanato (Porcelain Stoneware) and the results (valid for 8 mm thickness porcelain stoneware) are:
• Approx. 20 holes with FS6 (6 mm diametre) core bit (with regular cooling)
• Approx. 30/40 holes with FS8 FS10 FS12 FS14 FS16 FS20 (8, 10, 12, 14, 16, 20 mm diametres) core-bits (with regular cooling)
• Approx. 50/60 holes with all the rest of FS drilling tools from 27 mm to 75 mm diametre
Our latest suggestion is to cool during the use, all the FS core bits with diameters lower than 20 mm. It is enough to do one or more pauses during the drilling process, putting for 2 seconds, the tool head in a small glass of water without switching off the grinding machine. Following these simple tricks you can make more holes increasing the performance of your diamond core drill bits.
Life (+ 20% to 50% compared with other blades)* Performance (+ 100% compared with other blades)* Speed (+ 30% compared with other blades)*
* Test made on Montolit diamond blades
There are DNA diamond blades adapted for cutting the following materials: Granite; Marble; Concrete; Hard Stone; Abrasive Materials; Asphalt; Gres (Porcelain Stoneware); Ceramic; Building Industry.
Due to a very good and long technical partnership with our company, Cotto d’Este, one of the best tile producer worldwide, decided to insert Brevetti Montolit S.p.A in its technical documentation (ex. Kerlite – Cotto D’Este technical manual). This decision was made after successfully testing our tiling tools on different types of tiles, with a strong focus on the new thin tile named Kerlite.
We are proud of this partnership and, as usual, we will continue to work in order to support the tile companies to find the best solution to give to the layers the necessary tiling tools to cut and drill their new trendy products. For more detail: How to drill Kerlite
Test between standard professional blades against DNA Montolit technology blades. Which is the best diamond blade to cut concrete?
The movies show three comparative tests between diamond blades made with DNA technology and high-quality blades made from standard technology (nb. the 99,9% of the blades now in the market are made with standard technology). The images refer to hand held machine, paving saws and angle grinder and cuts have been implemented on a slab of concrete vibrated. In addition to the greater speed of DNA technology there is also a significantly longer duration and consistency of performance that this technology offers relative to the achievement standards.
If you need to make holes (from 6 to 75 mm) in marble and/or granite stones without using water, we suggest you to have a look at the video below (second part). With these diamond core-bits for dry drilling(FS items named Mondrillo) it is possible to make very good holes in a 2,5 or 3 cm marble or granite tiles in a few seconds.
How to drill Terrazzo Marble floor tile (composed of a mix between concrete, natural stones and resin) and obtain a perfect hole in a faster way?
After testing some different Montolit core drills (dry and wet use), in order to obtain a good result between speed and precision, we suggest that you use the art. FA (diamond core bit for wet use) with our drilling machine named “Bimbo Foratutto” . As usual we prefer to show you the video of the test: How to drill terrazzo marble floor tile
We received many requests about how to drill the innovative tile named Kerlite (3,5 mm thin) by Cotto D’este.
The frequent questions are the following:
Is it possible to make holes in Kerlite and with which drilling tools?
Is it possible to make holes in Kerlite with dry drilling tools(core bits)?
Which type of finishing is it possible to obtain?
How many holes can I make in Kerlite with dry core bits?
We think that the best way to give you the answers is to show you a real example. In the video below we made some different very small holes inside a Kerlite sample using different dry use drilling tools, our FTJ05 AND FTJ06 – FT10 – FS 08 and FS35.
As you can see looking at the video, with these core bits it is easy to make holes inside Kerlite tile and the finishing is very good. Concerning the number of holes, we can say that you can make the double (approx) numbers of holes compared a standard ceramic tile.
Please note that, specially for dry drilling in tiles, it is necessary to use the tools in a correct way.
Frequently the professional layer/tiler and also the DIY lover needs to make small holes (diametre 5; 6; 8; 10; 12 mm) on ceramic or Gres Porcellanato surfaces.
The traditional wet drillmade with classic diamond tools is quite difficult and not economic because it is necessary to buy and to use specific accessories to contain the water necessary to cool the core bit.
Furthermore, for the water drilling is necessary to buy a specific electric drill with the special safety system.
To solve this problem, only some months ago, the specialized professional tiling tools company developed and launched on the market a new series of diamond drills (core bit) for dry usewhich are able to work on standard electric drills.
These core drills with continued sintered diamond crown, if well used (looks the video), are able to make a great number of holes with an optimum level of precision and a good drilling speed. These core bits are able to cut every type of new generation of Ceramic or Porcelain tiles.
But how many holes can this type of dry use core bits make?
The correct answer is different and it depends on the type of material to drill (Ceramic, Gres Porcellanato, Granite, Marble etc) and of the thickness of the tile or stone.
Anyway, in order to give a basic answer, we can affirm for direct experience that, for example, the Montolit core drill dry use named FTJ (if it is well used!) on a 7 – 8 mm of Porcelain tile, well, this core bit dry use is able to make more than 40 holes without any problem.
The core bits dry use (FTJ) application range is very big:
Connection for sanitary Connection for furniture
Connection for windows
Connection for climatization
Realization of holes for pipes and cables
Today, the dry use diamond drills represent a small revolution for general layers, tilers, plumbers, electricians, and they are quickly substituting the classic, old and not appropriate Carburo di Tungsteno (Widia®) core bits for drills because these old Widia® tools are not able to drill new and very hard materials like the new generation of Porcelain tiles.
For the dry cutting of these new tiles, there is also on the market the electroplated vacuum core drills like the FS items(Mondrillo) by Brevetti Montolit (minimum rpm 10.000 with normal grinder machine). These core drills are much faster but they can make fewer holes compared to the sintered core bit that is possible to dress with special stones.
