Rotary Burr (ball) Beta Tools 426MD-S6 6 mm cutting head, carbide

Beta Tools rotary burr 426MD-S6 is a ball-shaped carbide cutting head with a 6 mm diameter designed for use with rotary tools and die grinders. It is intended for shaping, deburring and profiling on a variety of materials including ferrous and non-ferrous metals, plastics and composite materials. The carbide construction provides high wear resistance and stable cutting performance for fine finishing tasks and targeted material removal.

Advantages

The solid carbide ball cutter offers consistent cutting performance and extended life compared with high-speed steel alternatives. Its 6 mm cutting head enables precision access to tight radii and small cavities while maintaining control over chip size and surface finish. The tool is compatible with standard collet sizes used in rotary tools and die grinders, allowing straightforward fitting and repeatable results across machining and finishing operations.

Suitable for

• Shaping and profiling small radii and contours on metal components
• Deburring edges and removing flash from molded plastics and composites
• Finishing weld seams and removing weld spatter
• Precision material removal in mold and die maintenance
• Detail work and cavity smoothing in repair and restoration tasks

Key specifications

• Cutting head shape: ball (spherical)
• Cutting head diameter: 6 mm
• Material: solid carbide
• Intended mounting: rotary tools and die grinders with compatible collet
• Applications: shaping, deburring, profiling, weld cleaning

How to use

Install the rotary burr in a compatible collet or chuck and tighten according to the tool manufacturer’s instructions. Select appropriate rotational speed and feed for the workpiece material — lower speeds for plastics and composites, higher speeds for many metals while avoiding excessive heat. Apply light, steady pressure and use incremental passes to achieve the required shape or finish; intermittent contact or air/water cooling can help control temperature and reduce clogging. Clean the burr periodically to maintain cutting efficiency.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, dust extraction or respiratory protection when machining hazardous materials, and hearing protection as required. Match the rotational speed and feed to the material to maximise tool life and avoid overheating. For precision finishing, perform test cuts on scrap material to determine the optimal settings.
