Rotary Burr (spherical) Dedra 07F631 D6×5 mm, shank 6 mm

The Dedra spherical rotary burr 07F631 features a compact D6×5 mm cutting head and a 6 mm diameter shank designed to fit standard 6 mm collets and die grinders. Intended for precision metalworking and finishing, this small spherical burr enables controlled material removal in confined or hard-to-reach areas. The tool is suitable for working on a variety of materials including metals, plastics and composite substrates where a rounded profile and fine contouring are required.

Advantages

The spherical geometry provides consistent, rounded cuts and smooth transitions when deburring, shaping or blending surfaces. The 6 mm shank ensures compatibility with commonly used rotary tools and collets, offering secure mounting and stable operation. Its small head diameter allows detailed work in tight radii and recessed features while maintaining accurate material removal rates and predictable surface finish.

Suitable for

• Deburring and edge rounding in tight or recessed areas
• Shaping and contouring small radii on metal and plastic parts
• Removing weld spatter and blending joints
• Fine finishing and smoothing in mold, die and composite repair
• Precision material removal for model making and prototyping

Key specifications

• Cutting head shape: spherical (ball)
• Cutting head size: D6 × 5 mm (diameter × head length)
• Shank diameter: 6 mm for standard collet compatibility
• Application materials: ferrous and non-ferrous metals, plastics, composites
• Typical use: deburring, shaping, finishing, blending

How to use

Select a compatible die grinder or rotary tool with a 6 mm collet and securely mount the burr by tightening the collet according to the tool manufacturer’s instructions. Operate the rotary tool at the recommended speed range for the work material and burr type, using moderate pressure and smooth passes. Work progressively from light to heavier cuts to avoid excessive material removal and to preserve tool life. Maintain a steady hand and control the burr orientation to produce consistent spherical profiles and smooth blends.

Usage recommendations

Use appropriate personal protective equipment including eye protection, gloves and respiratory protection when working with metal or composite dust. For best results, keep the burr clean of clogged chips and inspect for wear; replace the burr if cutting performance declines or if damage is visible.
