Designed for professional use: drilling in high-grade stainless steel, structural steel, INOX and cold-rolled steel.

• HSS steel provides several times faster drilling and maintains resistance to damage and dulling, maintaining drill geometry
• cross-blade „split point” with an apex angle of 135° allows drilling without pre-scoring, guaranteeing perfect centering
• dissipate heat quickly when drilling in hard steels, without burning the drill bits
• grinded surface and edges to DiN 338 standard ensure excellent drilling precision and ideal dimensions of the drilled hole
• lower coófriction factor reduces the adhesion of swirlsórós and filings to the drill bits
• made from a single piece of HSS 6542 steel, making them strong and durable
• 1/4" HEX shank (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
