Sanded drills with aggressive blade geometry Thanks to the titanium nitride coating, they drain the heat very efficiently and do not move when working in hard steel species The blade attack of 135 & deg; It allows drilling even without prior use Made according to the DIN 338 standard for professional applications in industry Prepared for the standard handle & oacute; in drilling drills and key High pressure resistance also allows the use of column and magnetic drills Drilling in high -quality steel, including stainless, structural and cold rolled Drilling without the need for scoring, thanks to the aggressive geometry of the blade Quick heat dissipation allows you to work without the use of a cooling factor, without causing a drill burning.
