Metal drill bits HSS rollforged - DIN 338 HSSR 9.0 x 125

The Milwaukee HSS‑R Metal Drill Bit 9.0 × 125 mm (Part No. 4932363524) is engineered for consistent and durable drilling performance in metal applications. Manufactured from roll‑forged high-speed steel according to DIN 338, it features a black oxide finish to facilitate chip evacuation and reduce friction. With a standard 118° cutting point and neutral‑angle flute design, it is suited for drilling in steel, cast iron, and alloyed or non-alloyed metals with tensile strength up to ~ 800 N/mm². It is commonly supplied in packs of 10, making it suitable for workshop and industrial use.
