Description

25 Piece cobalt twist drill bit set TDC.25, for precise and efficient drilling in hard materials and high-alloy steel. Designed for structural drilling, high-strength alloyed and high-viscosity steels, such as stainless steel. The 5% cobalt content ensures superior heat resistance and mechanical properties. 135° Point angle provide high-precision drilling without the need for pre-holes or centering. High-performance cutting edge of these twist drills reduces cutting forces. Split point design allows for quick and simple spot-drilling. 40º Helix spiral ensure fast and efficient chip removal, providing a high cutting speed and increased accuracy. DIN 338 twist drills are very universal drill bits with excellent stability. Newly added 3-flat shank design provides better grip, optimal power transmission and excellent clamping in the drill chuck, preventing spinning or slipping under high torque loads. Ideal for demanding industrial and general-purpose projects.
