Double-sided ground drill bits with a wide range of applications in industry and crafts. They are perfect for drilling in thin sheet metal and metal as well as in plastics, including for car bodies, body assembly, drilling holes for rivets in metal elements.

HSS steel provides several times faster drilling and maintains resistance to damage and blunting, maintaining the geometry of the drill bits
cross blade "split point" with a point angle of 135 allows drilling without prior punching, ensuring perfect centering
double-sided point angle extends the service life of the drill bits
ground surface and edges according to DiN 338 standard ensure perfect drilling precision and perfect dimensions of the drilled hole
the lower friction coefficient reduces the sticking of chips and filings to the drill bits
The set includes 10 double-sided ground drill bits with diameters of 3.0, 3.2, 3.5, 4.0, 4.2, 4.5, 5.0, 5.2, 5.5, 6.0 mm, packed in a handy case.
