Carbide Rotary Burr Set for Metal GEKO 6 mm shank, 6-piece (20/40 grit)

GEKO Carbide Rotary Burr Set for Metal with 6 mm shank is a six-piece collection of tungsten carbide burs designed for precision metalworking. The set includes cutters in two grit sizes (20 and 40) suited for shaping, deburring, weld seam removal and fast material removal on steel, cast iron and non-ferrous metals. Each burr fits standard handheld die grinders and rotary tools with a 6 mm collet, providing a compact, replaceable cutting solution for professional workshops and home fabrication projects.

Advantages

The tungsten carbide construction offers high wear resistance and sustained cutting performance on hard materials. Two grit types (coarser 20 and finer 40) allow selection between aggressive material removal and smoother finishing passes. A uniform 6 mm shank ensures compatibility with common die grinders and rotary tools, enabling quick tool changes and stable rotation. The set format supplies multiple burrs to cover different stages of metal preparation and repair without frequent purchases of single pieces.

Suitable for

• Shaping and profiling steel parts
• Deburring edges after cutting or machining
• Removing weld seams and smoothing joints
• Material removal on cast iron and non-ferrous metals
• Detail work in automotive, metal fabrication and repair

Key specifications

• Material: tungsten carbide cutting head
• Shank diameter: 6 mm
• Quantity: 6 pieces per set
• Grit sizes included: 20 (coarse) and 40 (medium-fine)
• Intended materials: steel, cast iron, non-ferrous metals

How to use

Secure the appropriate burr in a die grinder or rotary tool with a 6 mm collet and tighten according to the tool manufacturer’s instructions. Start at low speed to seat the burr and verify concentricity, then increase speed to the recommended operating range for the tool and material. Apply steady, controlled pressure; let the carbide cutting edges do the work rather than forcing the tool. Use the coarser 20-grit burrs for rapid stock removal and shaping, then switch to 40-grit burrs for smoothing and finishing passes. Periodically clear chips from the cutting surfaces and observe appropriate cooling intervals on prolonged use to avoid overheating the workpiece or burr.

Usage recommendations

Wear appropriate personal protective equipment: eye protection, gloves and respiratory protection when cutting metals. Match rotational speed to burr size and workpiece material, and avoid side-loading the shank to reduce the risk of breakage. For best results, maintain a clean collet and check the burr for wear before use; replace when cutting performance declines.
