Metal drill bits HSS rollforged - DIN 338 HSSR 5.0 x 86

The Milwaukee HSS‑R Metal Drill Bit 5.0 × 86 mm (Part No. 4932363484) is designed for consistent and durable performance in metalworking tasks. Constructed from roll‑forged high‑speed steel in compliance with DIN 338, it includes a black oxide coating to facilitate efficient chip removal and reduce friction during drilling. With standard geometry and flute design, it is suitable for drilling steel, cast iron, and alloyed or non‑alloyed metals with tensile strength up to approximately 800 N/mm². The drill bit comes in packs of 10, making it ideal for workshop and industrial use.
