RUKO SPB-DIN338-HSSCo8-Ø13,5mm σπειροειδές τρυπάνι

Drilling into tough materials like stainless steel or high-alloy steel quickly dulls ordinary bits. This RUKO twist drill bit is made from HSS-Co 8% cobalt steel, so it stays sharp and withstands high heat. The 135° self-centering point starts cleanly without wandering, and the bright finish reduces friction for smoother drilling.
