3x3mm Tungsten Rotary Burr Set – Versatile Carving Tools for Metal & More
Burr Rotary File Overview
This 3mm diameter tungsten carbide rotary burr set (also known as tungsten steel grinding heads) is engineered for precision material removal on both hard metals and non-metallic materials like marble, jade, and bone. Manufactured from high-grade YG8 tungsten carbide, these burrs offer excellent wear resistance and impact toughness, making them ideal for detailed shaping, deburring, and cavity finishing.
Each burr features a 3mm shank diameter and a 38mm overall length, with varying blade lengths and profiles to suit different tasks. The set is supplied in a convenient 10‑piece package (per model), ensuring you have the right shape for intricate work on power tools, pneumatic tools, or mounted on machine tools at speeds from 6,000 to 50,000 RPM.
Key Features & Benefits
- Premium Material – Made from YG8 tungsten carbide (ISO grade K10/K20 equivalent), offering superior hardness (≥89.5 HRA) and transverse rupture strength for heavy‑duty use.
- Wide Material Compatibility – Effectively machines steel, cast iron, bearing steel, high‑carbon steel, alloy steel, stainless steel, copper, aluminum as well as marble, jade, bone, and other non‑metals.
- High Surface Finish – Precision‑ground flutes produce smooth, burr‑free surfaces, reducing secondary finishing work.
- Versatile Shape Selection – Available in cylindrical, cylindrical with dome, spherical, oval, curved tip, conical, torch‑shaped, and inverted conical profiles to match complex contour requirements.
- Standardized Shank – Uniform 3mm shank diameter ensures quick changeover and compatibility with most collet systems.
- Efficient Chip Evacuation – Single‑cut and double‑cut (cross‑cut) options available; double‑cut (X‑type) provides finer finish and faster stock removal.

FAQ
A1: Yes, they are designed for power tools and pneumatic tools operating at 6,000 – 50,000 RPM. Always follow the recommended speed for your material.
A2: Absolutely. YG8 carbide works well on stainless steel, alloy steel, and cast iron. For best results, use a double‑cut (X‑type) for a finer finish.
A3: Yes, we accept OEM orders for non‑standard profiles, lengths, or coatings. Please contact us with your specifications.
A4: Single‑cut (standard) provides faster stock removal and is more aggressive. Double‑cut (X‑type, with two intersecting flutes) produces a smoother surface and is preferred for finishing and harder materials.
