Izar, continuing with its philosophy of offering solutions to work with the most difficult materials, has designed a drill with a unique geometry, highlighting the unique sharpening of its carbide tip and a special weld that prevents insert breakage. The tip also features asymmetric grinding that reduces cut resistance and increases the tool’s life.
As for how to use it, it is recommended to use it with water cooling to increase its durability, although Black Granite also drills dry granite.
The Black Granite drill bit range is available in diameters from 3 to 10mm and is presented in the blister Ev-pack IZAR, designed especially for presentation on the shelf of hardware and supplies stores.
Izar Cutting Tools has been manufacturing and selling cutting tools (bits, milling cutters, taps, etc.) for industrial and professional use since 1910. They are leaders in Spain and export to 90 markets around the world.
