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