D-Type Ball-Nose Tungsten Carbide Rotary Burr

Our Type D rotary file delivers precision metal shaping and deburring in one tool. It features a ball-nose head, tungsten-carbide construction, and is offered in single-cut or double-cut flute patterns for both aggressive material removal and smooth finishing.

The D-Type Ball-Nose Tungsten Carbide Rotary Burr is engineered for high-precision carving, edge deburring, and surface profiling on ferrous and non-ferrous metals. Constructed from pure tungsten carbide, it withstands high RPMs and abrasive work without premature wear. Available in diameters from 6 mm to 16 mm, the burr’s standard 6 mm straight shank fits most die grinders and rotary tools.

Key Features

• Ball-Nose (Type D) Geometry:
  The round-ball profile excels at contouring, drilling relief cuts, and finishing internal radii with minimal tool marks.

• Single vs. Double Flute Options:

  • Single-Cut: Spiral flute for high stock removal and rough sculpting.

  • Double-Cut: Cross-cut flutes produce smaller chips, smoother finishes, and improved control on harder materials.

• CNC-Precision Flutes:
  Five-axis CNC grinding ensures uniform flute geometry, balanced cutting action, and vibration-free operation.

• Universal 6 mm Shank:
  Straight-shank design for secure mounting in most rotary and pneumatic grinders.

• High-Speed Capability:
  Rated for up to 45,000 RPM in wet or dry applications, enabling fast, efficient removal on stainless steel, cast iron, aluminum, and non-metals.

Specifications

Applications

• Metal Carving & Sculpting: Create intricate reliefs and 3D profiles on steel, brass, and aluminum.

• Deburring & Chamfering: Remove sharp edges, weld spatter, and burrs from castings and machined parts.

• Mold & Die Maintenance: Finish internal radii and smooth tooling cavities with precision.

• Wood & Non-Metal Carving: Suitable for hardwoods, plastics, and composite materials in artistic and prototype work.

Benefits

• Extended Tool Life: Superior carbide alloy resists wear under heavy impact and high temperature.

• Versatility: Single and double-cut options address both rough and fine machining tasks.

• Precision: Engineered flute geometry ensures consistent chip control and surface finish.

• Compatibility: Standard shank and RPM rating make integration into existing tool setups seamless.

This Type D Ball-Nose Tungsten Carbide Rotary Burr is the professional’s choice for high-precision carving, deburring, and finishing across diverse materials and applications.
