Twist drill

A ground drill with aggressive blade geometry. Thanks to the titanium nitride coating, it drains heat very efficiently and does not move when working in hard steel species. The blade attack angle of 135 ° allows drilling even without prior use of a point. Made according to the DIN 338 standard for professional applications in industry. A drill with a cylindrical handle designed for standard self -stacking drilling holders 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.
