      Tungsten Carbide Rotary Burrs are high-performance cutting tools designed for precision shaping, grinding, deburring, and material removal on hard surfaces. Manufactured from ultra-hard cemented carbide (WC-Co), they excel in demanding applications where speed, durability, and fine detail are critical.

      Key Features

      1. Exceptional Hardness & Wear Resistance

        • Hardness: HRA 90–93

        • Outlasts HSS tools by 10x+ lifespan.

      2. High-Temperature Stability

        • Maintains cutting edge integrity up to 800°C (1472°F).

      3. Versatile Cutting Geometry

        • Single-cut (Aluma-cut): Aggressive material removal (soft metals, wood).

        • Double-cut (Standard): Balanced efficiency/surface finish (steel, stainless steel).

        • Fine-cut (Multi-cut): Smooth finishing (hard alloys, composites).

      4. Multi-Shape Design

        • Cylindrical, Ball, Oval, Tree (Taper), Flame, and Inverted Cone profiles.

      Primary Applications

      • Deburring: Remove sharp edges from machined parts.

      • Chamfering/Beveling: Create precise angles on edges.

      • Mold & Die Correction: Refine complex contours in tooling.

      • Weld Seam Cleaning: Smooth weld overflows.

      • Detail Carving: Engraving, grooving, and sculpting.

      Industry Use Cases

      • Metalworking: Automotive/aerospace component finishing.

      • Foundries: Casting flash removal.

      • Medical Device Manufacturing: Implant polishing.

      • Woodworking & Composite Fabrication.

      Technical Guidance

      • Speed:

        • Ø ≤6mm: 30,000–50,000 RPM

        • Ø >6mm: 15,000–25,000 RPM

      • Operation: Use in climb milling direction; apply coolant for ferrous metals.

      • Safety: Always wear ANSI-rated eye protection.

      Optional Coatings

      • TiN (Gold): General-purpose wear resistance.

      • TiAlN (Violet): Enhanced thermal barrier for stainless steel/nickel alloys.
