Euroboor Twist Drill Bit Set, TDC-25, HSS-CO, 25 Pcs/Set

This Drill Bit set contains 25 HSS-CO (5%) twist drills with a 135 degree point angle for drilling in hard materials and high alloy steel. The high performance cutting edge ensures a very high aligned preciseness, particularly when hand-operated with a cordless drilling machine. Due to the reduced cutting forces you need less drilling power which makes your battery last longer! With the split point on our twist drills you get quick and simple precise spot-drilling without pre-centering. Even on ridged areas or materials! The 40 degree helix spiral enables a perfect and fast chip removal. It provides a high cutting speed along with increased accuracy. Euroboor DIN 338 twist drills are very universal drill bits with excellent stability. Ideal for general purposes or industrial projects! The HSS-CO twist drills (Dia 4-13 mm) are now equipped with the new 3-flat shank to provide better grip, optimal power transmission and an excellent clamping in the drill chuck. The 3 flats prevent the drill from spinning or slipping under high torque loads. This is ideal for cordless drills!
