Broca helicoidal RUKO SPB-DIN338-6,7mm-HSSCo, HSS-Co 5% cobalto, DIN 338, 6,7 mm, afiação de ponta 135°

Twist drill bit with 6.7 mm diameter, manufactured from HSS-Co (5% cobalt) for high heat resistance and extended tool life. The 135° split point provides self-centering and reduces walking, enabling precise hole positioning without a center punch.

Advantages

Fully ground from solid HSS-Co 5% cobalt steel, this drill bit withstands high temperatures and maintains hardness during demanding drilling tasks. The split point design ensures accurate starts and clean holes, while the bright/bronze finish reduces friction and improves chip evacuation.
