CNC drill bits for stone and composite
Diamond drill bits from Diamut for precise drilling in granite, quartz, and ceramic materials on CNC machines.
Diamut CNC drill bits for industrial stone processing
CNC drill bits for stone are used for precise drilling in granite, quartz, marble, and technical materials where accuracy and stable operation are crucial. The bits are developed for use on CNC machining centers and are an integral part of modern countertop production and industrial stone processing.
At Per Mordt, we offer diamond drill bits from Diamut – part of Biesse Group – developed for efficient material removal, controlled cooling, and long lifespan in continuous production.
Diamut's solutions cover both through holes and blind holes, adapted to various diameters, material types, and machine configurations.
Common for Diamut CNC drill bits is high precision, stable geometry, and even wear. This provides predictable performance, reduced vibration, and optimal quality of the finished drilled hole – both in single operations and series production.
Continuous CNC drill bits
Continuous CNC drill bits from Diamut are equipped with a continuous diamond ring that provides even and controlled drilling. This construction reduces vibrations and gives cleaner hole edges, which is especially important for visible through holes in countertops and interior solutions.
The bits are often used in marble, granite, and technical materials where finish and precision are decisive. The continuous ring provides stable advancement and good control at high revolutions per minute on CNC machines.
Segmented CNC drill bits
Segmented CNC drill bits are developed for demanding processing in hard stone materials such as granite and composite (engineered stone). The diamond segments are separated, which provides effective cooling and optimal removal of slurry and chips during drilling.
This construction makes the bits well suited for larger diameters and high loads in continuous production. Segmented bits combine high cutting capacity with long lifespan and stable performance, even with intensive use on CNC machining centers.
Blind hole drills
Blind hole drills are used when the hole should not go all the way through the material. The bits are designed for precise depth control and controlled entry, which is important for technical connections, grooves, and mounting details in stone plates.
The construction ensures stable drilling without breakthrough and is often used in the production of kitchen countertops, sink solutions, and other components where accuracy and repeatability are crucial.
