Rotary metal file GEKO G37506 — spherical head 10×9 mm, 6 mm shank (pack 200)

Rotary metal file GEKO G37506 is a spherical-head rotary burr with a 10×9 mm cutting head and a 6 mm shank supplied in a pack of 200. Designed for use with rotary tools and die grinders, this burr is intended for shaping, deburring and controlled material removal on metals and hard alloys. The rounded cutting profile allows access to cavities and concave surfaces while providing a predictable finish on edges and contours.

Advantages

The spherical (ball) head provides smooth, uniform contact on curved and recessed areas, reducing the risk of gouging. A 6 mm shank ensures stable mounting in standard collets and chucks of handheld rotary tools and pneumatic die grinders. Supplied in bulk packaging of 200 pieces, the set supports repetitive workshop tasks and production runs where frequent tool change is required. The geometry of the teeth is optimized for efficient metal removal and consistent chip evacuation in small-radius applications.

Suitable for

• Shaping and contouring of metal surfaces
• Deburring edges and removing weld beads in tight or curved zones
• Creating and finishing cavities, grooves and concave profiles
• Material removal on hard alloys, stainless steel and castings
• Precision work in workshops, fabrication and tooling maintenance

Key specifications

• Cutting head shape: spherical (ball)
• Head dimensions: 10 × 9 mm (approximate cutting diameter × head length)
• Shank diameter: 6 mm
• Material type: rotary burr for metal and hard alloys
• Pack quantity: 200 pieces
• Typical mounting: compatible with standard 6 mm collets and chucks

How to use

Install the rotary burr into a suitable rotary tool or die grinder and secure it in the collet or chuck to the recommended depth. Operate the tool at speeds appropriate for the workpiece material and burr geometry; use steady, controlled passes for shaping and deburring to avoid excessive stock removal. Apply light pressure and keep the burr moving across the work surface to maintain a consistent finish and prevent heat buildup. For precision cavity work, use small incremental cuts and check the fit frequently.

Usage recommendations

Wear appropriate eye, respiratory and hand protection when grinding or deburring metals. Use cutting fluid or intermittent cutting to reduce heat when working with stainless steel or heat-sensitive alloys. Replace burrs that show excessive wear, broken teeth or imbalance to maintain safety and consistent cutting performance.
