Rotary Carbide Burr SUZHOU-CHINY 426MD-3/TA3, tapered rounded tip, 3 mm

Rotary carbide burr SUZHOU-CHINY 426MD-3/TA3 features a tapered profile with a rounded tip and a 3 mm cutting diameter. Constructed from solid carbide, this rotary tool accessory is intended for cutting, shaping and deburring a variety of materials including metals, wood, composites and plastics. The compact tapered shape and small rounded tip provide access to confined areas and allow for controlled material removal and precision profiling during use in rotary tools, die grinders and drills.

Advantages

The tapered rounded tip delivers fine control for contouring and profiling while the carbide construction offers high wear resistance and sustained cutting performance. Its 3 mm diameter is suited to detailed work and precision finishing where larger burrs would be impractical. The tool's geometry reduces vibration and provides stable cutting behavior for consistent surface results.

Suitable for

• Precision profiling and contouring of metal parts
• Deburring edges and removing flash from castings
• Detail work on wood, plastic and composite components
• Accessing tight or recessed areas for finishing

Key specifications

• Cutting head shape: tapered with rounded tip
• Effective cutting diameter: 3 mm
• Material: solid carbide cutting head
• Compatible tools: rotary tools, die grinders, drills with appropriate collet/chuck
• Typical applications: cutting, shaping, deburring, surface finishing

How to use

Secure the burr in the tool collet or chuck following the rotary tool manufacturer's recommendations, ensuring the shank is firmly seated and runout is minimized. Start at low to moderate speed to establish control, then adjust rotational speed and feed pressure according to the workpiece material and desired finish. Use light, steady passes and avoid excessive force to prevent premature wear or chipping of the carbide cutting edges. When working on delicate areas, perform trial cuts on scrap to determine optimal speed and contact angle.

Usage recommendations

Wear appropriate personal protective equipment such as safety glasses, hearing protection and a dust mask. Secure the workpiece and keep hands clear of the rotating burr. For best results, select speeds and feed rates matched to the material: lower speeds for hard metals, moderate to higher speeds for softer metals, wood and plastics. Clean the burr periodically to remove built-up material and inspect for wear; replace the tool when cutting performance diminishes.
