RUKO helical drill bits, pack of 10, HSS milled-ground, Ø 9.5 mm.

The 10-pack of TURBO DIN 338 HSS milled-ground twist drill bits (Ø 9.5 mm) is specifically designed for drilling thin sheets and profiles. With a 130° cutting angle and a 56° spiral angle, these drill bits guarantee optimal performance in metallic materials, producing clean, burr-free holes. Their h8 tolerance and right-hand cutting ensure exceptional precision with every use, making them an indispensable tool for high-quality work.

These drill bits are ideal for drilling cast steel, both alloyed and non-alloyed, with a tensile strength of up to 900 N/mm². Their design allows drilling thin sheets and profiles up to 5.0 mm thick, as well as wood and plastic.
