Description
Double-sided ground drill with a wide range of applications in industry and crafts. It is perfect for drilling in thin sheet metal and metal as well as in plastics, e.g. car bodies, body assembly, drilling holes for rivets in metal elements.
- HSS steel provides several times faster drilling and is resistant to damage and blunting, maintaining the geometry of the drill bits
- the "split point" cross blade with a point angle of 135° allows drilling without prior scoring, guaranteeing perfect centering
- the point angle on both sides extends the life of the drill bits
- ground surface and edges according to DIN 338 standard ensure excellent drilling precision and ideal dimensions of the drilled hole
- the lower coefficient of friction reduces the sticking of chips and swarf to the drill bits
