Rotary burr for metal GEKO G37508, 10×20 mm cutting head, 6 mm tapered shank

The GEKO rotary burr G37508 is designed for metalworking tasks that require controlled material removal and shaping. Featuring a 10×20 mm cutting head and a 6 mm tapered shank, this rotary file attachment is compatible with rotary tools and die grinders that accept the same shank diameter. It is intended for use on a variety of metals and engineered to provide consistent cutting performance for trimming, deburring and preparing surfaces prior to welding or finishing.

Advantages

The compact cutting head size allows for access to confined areas and accurate contouring, while the tapered 6 mm shank ensures a secure fit in collets and chucks designed for that shank diameter. The burr’s cutting geometry is optimized for efficient material removal and reduced clogging on metal surfaces. Its construction delivers repeatable results when shaping edges and removing flash or weld spatter.

Suitable for

• Trimming and shaping metal workpieces
• Deburring edges and removing burrs after machining
• Preparing weld seams and cleaning up weld spatter
• Detail grinding in confined or hard-to-reach areas

Key specifications

• Cutting head diameter and length: 10×20 mm
• Shank type: tapered shank
• Shank diameter: 6 mm
• Suitable material: metals (steel, stainless steel, cast iron, non-ferrous metals, depending on burr grade)
• Typical applications: shaping, deburring, material removal, weld preparation

How to use

Fit the 6 mm tapered shank securely into a matching collet or chuck of a rotary tool or die grinder. Operate the tool at the manufacturer-recommended speed for the specific metal being worked to achieve efficient cutting and avoid overheating. Apply light, steady pressure and move the burr along the workpiece in smooth passes to control material removal; avoid forcing the tool to prevent premature wear. Use appropriate cooling or intermittent cutting when working with heat-sensitive alloys.

Usage recommendations

Always wear appropriate personal protective equipment such as eye protection, gloves and hearing protection. Inspect the burr before use and replace it if the cutting edges are worn or damaged. Match the tool speed and feed to the workpiece material and consider using cutting fluid or air cooling for extended operations.
