Rotary Cutter Bit Beta Tools 426MD-FA6 rounded arc 6 x 19 mm

The Beta Tools rotary cutter bit 426MD-FA6 with a rounded arc profile measures 6 x 19 mm and is intended for shaping, deburring and profiling on metal and other machinable materials. The cutter presents a defined cutting geometry that produces consistent arc-shaped grooves and edge radii when mounted in compatible rotary tools. Its compact dimensions make it suitable for detailed work in workshop and industrial settings where repeatable curved contours and smooth transitions are required.

Advantages

This rotary cutter bit provides precise, repeatable arc profiles thanks to its rounded cutting edge and stable geometry. The 6 mm cutting diameter combined with a 19 mm overall length offers a balance between accessibility and control when working in confined areas. The design minimises chatter and enables smooth deburring and edge finishing while preserving material integrity. The bit is compatible with standard rotary tool collets that accept its shank diameter, allowing straightforward replacement and quick tool setup.

Suitable for

• Shaping and profiling arc-shaped grooves in metals and machinable materials
• Deburring edges and smoothing transitions after cutting or milling
• Creating consistent edge radii and ornamental curved details
• Detail work in tool rooms, maintenance and light production environments

Key specifications

• Profile type: rounded arc
• Cutting diameter: 6 mm
• Overall length: 19 mm
• Intended materials: metals and other machinable materials
• Application: shaping, deburring, profiling

How to use

Install the rotary cutter bit in a compatible rotary tool or die grinder using the correct collet size for a secure, concentric fit. Run the tool at speeds appropriate for the material being worked, and apply light, steady pressure while following the intended contour to produce a uniform arc profile. Avoid excessive feed rates and heavy side loads that can damage the cutting edge or produce undesired marks. Periodically inspect the bit for wear and replace it when cutting performance declines to maintain consistent results.

Usage recommendations

Use appropriate personal protective equipment, including eye protection and gloves, and secure the workpiece before machining. Select cutting speeds and coolant or air blast as needed for the specific material to reduce heat build-up and extend tool life.
