Advanced Cutting Tools: Annular Cutters, Core Cutters, and Carbide Burrs

Introduction

Traditional drill bits struggle with thick metal, but annular cutters and carbide burrs offer precision and speed. At Asas-Trading, we supply premium tools like Callington annular cutters and Arcaire TCT core cutters for industrial applications. Learn how these tools revolutionize metal cutting.


1. Annular Cutters vs. Drill Bits: Why Upgrade?

Annular cutters (aka core cutters) remove a ring of material, leaving a clean hole with minimal effort.

  • Benefits:
    • 3x faster than standard drill bits.
    • Less heat generation (extends tool life).
    • Cleaner holes for bolts, pipes, or wiring.
  • Asas-Trading’s Recommendation:
    • TCT Annular Cutters: Tungsten carbide teeth cut through stainless steel and cast iron.
    • Callington Cutters: Ideal for CNC machines and mag drills.

2. Carbide Burrs: Precision in Detail Work

Carbide burrs excel in shaping, deburring, and engraving metals.

  • Shapes:
    • Ball Nose: Smoothing concave surfaces.
    • Tree Burr: Reaching tight corners.
    • Flame Burr: General-purpose grinding.
  • Asas-Trading’s Range:
    • Double-cut burrs for fine finishes.
    • Compatible with die grinders and rotary tools.

3. Arcaire Core Cutters: Built for Heavy Industry

Arcaire’s TCT core cutters are engineered for demanding environments:

  • Cobalt Alloy Body: Resists heat and wear.
  • Quick-Change Shanks: Fit mag drills and handheld units.
  • Applications: Shipbuilding, structural steel, and HVAC.

4. Maintenance Tips for Longevity

  1. Use cutting fluid to reduce friction (especially with TCT annular cutters).
  2. Store carbide burrs in foam-lined cases to prevent chipping.
  3. Clean core cutters after use with a wire brush.
