Stoneware core bit d.10mm hexagonal connection

Core bit with 2.2 mm thick crown, 10 mm high for dry drilling and with hexagonal drill attachment: drilling without percussion, optimal speed 11,000/13,000 rpm.
This diamond core bit is made with special diamond placed with vacuum galvanic process which guarantees the tool a high drilling speed and a long life.
For porcelain stoneware, ceramics in general and natural stones. Not suitable for glass. It is possible to drill dry thanks to the wax present inside the core bit, which prevents overheating. For a higher performance, cool down while drilling by repeatedly extracting and reinserting the tool into the hole. For optimal durability, we recommend working wet or with "DRILL GEL". Start drilling at a 45° angle, then proceed in a circular motion. Attention: the tool that is no longer sharp is used up (not redressable) while maintaining the dimensions and appearance equal to the new one.
