TIMCO HSS-M Blacksmith Drill Bit 18.5mm | BSD185

TIMCO BSD185 HSS‑M Blacksmith Drill Bit (Black Oxide) – 18.5mm

TIMCO BSD185 is an HSS blacksmith drill bit designed for fast, consistent drilling of larger diameter holes in non-alloy materials, making it a practical choice for fabrication and general engineering work. Made from M2 grade high speed steel with a black oxide finish, it’s built for durability and reliable cutting performance.

The 118° split point helps the bit start cleanly with reduced wandering, which is especially useful when working on sheet metal. The BSD185 is supplied with a 12.5mm shank for use in a 1/2" chuck.
