Rotary burr KWB 700340 — HSS conical head Ø12 mm, shank Ø6 mm, for stainless steel

Rotary burr KWB 700340 is a single-piece high-speed steel (HSS) tool with a conical head and a 6 mm shank, designed for cutting, shaping and finishing stainless steel and other metals. The burr has a 12 mm head diameter and is made for use in handheld die grinders and rotary tools with standard 6 mm collets. It is suitable for material removal, deburring and profiling tasks in metalworking, plumbing and repair work.

Advantages

The HSS conical rotary burr provides durable cutting performance on stainless steel, with a precise conical shape that allows access to tight spots and tapered surfaces. Its single-piece construction and 6 mm shank ensure compatibility with common handheld grinders and resist loosening during operation. The 12 mm head offers a balance between material removal rate and control for finishing operations.

How to use

Fit the burr into a compatible collet (6 mm) of a handheld die grinder or rotary tool and tighten according to the tool manufacturer's instructions. Start at low speed to check clearance and then increase to the recommended operating speed for HSS burrs. Apply steady light pressure and move the burr across the workpiece to remove material, deburr or shape surfaces; avoid excessive force to prevent premature wear or tool breakage. Use appropriate cutting directions for profiling and keep the burr moving to prevent heat buildup.

Recommendations

Use personal protective equipment (safety glasses, gloves and hearing protection) and ensure the workpiece is securely clamped. Match the grinder's speed to the manufacturer's guidance for HSS rotary burrs, and periodically inspect the burr for wear; replace if blunted or damaged.
