CNC drills for stone and composite
Diamond CNC drills from Diamut for precise drilling in granite, quartz, and ceramic materials.
Diamut CNC drills for industrial stone processing
CNC drills for stone are used for precise drilling in granite, quartz, marble, and technical materials where accuracy and stable operation are crucial. The tools 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 CNC drills from Diamut – part of Biesse Group – developed for efficient material removal, controlled cooling, and long tool life in continuous production.
Diamut's solutions cover both through holes and blind holes, adapted to different diameters, materials, and machine configurations.
Diamut CNC drills are characterized by high precision, stable geometry, and even wear. This ensures predictable performance, reduced vibration, and consistent quality of the finished hole – both in single operations and series production.
Continuous rim CNC drills
Continuous rim CNC drills from Diamut are equipped with a continuous diamond rim that ensures even and controlled drilling. This design reduces vibration and delivers clean hole edges, which is especially important for visible through holes in countertops and interior applications.
The drills are commonly used in marble, granite, and technical materials where finish and precision are critical. The continuous rim ensures stable feed and precise control at high revolutions per minute on CNC machines.
Segmented CNC drills
Segmented CNC drills from Diamut are developed for demanding processing in hard stone materials such as granite and engineered stone. The segmented diamond design ensures efficient cooling and optimal removal of slurry and chips during drilling.
This construction enables high cutting capacity, stable performance, and long tool life, even under intensive use in continuous production. The drills are well suited for larger diameters and high loads on CNC machining centers.
Blind hole drills
Blind hole CNC drills are used when the hole should not go all the way through the material. The drills are designed for precise depth control and controlled entry, which is important for technical connections, grooves, and mounting details in stone slabs.
The design ensures stable drilling without breakthrough and is commonly used in the production of kitchen countertops, sink cut-outs, and other components where accuracy and repeatability are critical.
