BDS HSS Standard Annular Cutter 13.0 mm Cutting Diameter, 30 mm Cutting Depth, Weldon Shank (KBK-013)

Drilling large-diameter holes in steel often requires a heavy twist drill and a lot of power. This BDS annular cutter removes only a ring of material, leaving a solid slug, so you need less force and get a cleaner hole faster.

Who is it for

Metalworking professionals and serious DIYers who use magnetic drilling machines and need precise, repeatable holes in structural steel, cast iron, or non-ferrous metals.

Main features

• High-speed steel (HSS) body for durability and heat resistance.
