For aggressive grinding with the highest stock removal rates on hard materials which do not conduct heat well. - Consistently high performance due to self-sharpening ceramic oxide grain. - Active grinding additives in the coating substantially improve the stock removal rate, prevent clogging and result in cooler grinding. - Abrasive: Ceramic oxide grain CO-COOL
-Helical tip from the end of the thread, allowing a better displacement in the wood during screwing and increasing the final adhesion. -Threading thread 40º and optimized pitch for a smooth but fast penetration. -25º tip, which allows easy centring and drilling even in harder woods.
