In a nutshell
The right choise for
With the Milwaukee hss-r din 338 metal drill bit, you drill precise 17 mm holes in steel, cast iron, and alloyed or non-alloyed materials up to 800 N/mm². The cylindrical reduced shank allows you to use this large-diameter bit directly in standard drill chucks, eliminating the need for heavy machinery with oversized collets. Built to din 338 standards from resilient hss-r steel, it withstands demanding workshop and maintenance tasks. The black oxide coating and type n flute with a 118° point angle quickly clear swarf and minimize friction, helping you work smoothly and efficiently.
