Metalworking Carbide Burr and Tungsten Carbide Rotary Burr

Tungsten carbide is much harder than high-speed steel (HSS), stainless steel, and ordinary abrasives. It stays sharp far longer, so burrs wear down slowly even when machining hard metals.Carbide burrs typically last 10 to 20 times longer than HSS burrs, reducing tool replacement frequency and overall cost.

Key Properties

 
  • Extreme hardness: Mohs ~9.5 (second only to diamond), far harder than steel.
  • Super wear resistance: Lasts 3–5× longer than high‑speed steel (HSS) burrs.
  • Heat resistance: Maintains cutting performance at high temperatures.
 

Structure

 
  • Head: The cutting part, precision‑ground with flutes (single‑cut or double‑cut).
  • Shank: A steel or carbide stem (typically 1/8" or 1/4" diameter) for clamping.
  • Connection: Usually silver‑brazed or welded for strength.
  • Two parts:The head is made of tungsten carbide and the handle is made of steel. The head and handle are welded together using sandwich welding plates through high-temperature melting. 
 

Common Shapes

 
  • Ball/round: For contouring, blending, and hollowing.
  • Cylindrical: For flat surfaces, deburring, and slotting.
  • Tapered/pointed: For detail work, engraving, and reaching tight spaces.
  • Tree/ogive: For shaping and finishing curved surfaces.
  • Countersink: For chamfering holes.
 

Typical Uses

 
  • Deburring & edge breaking: Removes sharp edges from metal parts.
  • Weld preparation & cleanup: Shapes welds and removes excess material.
  • Shaping & contouring: Used in mold making, metal carving, and jewelry.
  • Grinding & milling: Works on steel, stainless steel, aluminum, titanium, cast iron, plastics, and wood.
 

Applications

 
  • Automotive, aerospace, mold & die, metal fabrication, dentistry, and hobby carving.
