Description
Intended for professional use: drilling in high-quality stainless steel, structural, INOX and cold-rolled steel.
- 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
- quickly dissipate heat when drilling in hard steels, without burning 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
- made of one piece of HSS 6542 steel, making them strong and durable
- HEX 1/4" (6.3 mm)
The set includes 10 HSS drill bits with diameters: 1.5, 2.0, 2.5, 3.0, 3.2, 3.5, 4.0, 4.5, 5.0, 6.0 mm, packed in a handy case
