Our Tungsten Carbide Gritted Hole Saw redefines cutting performance in the most challenging drilling applications. Unlike conventional bi-metal or diamond hole saws, this professional-grade tool features a revolutionary tungsten carbide grit matrix permanently fused to a high-tensile steel body, delivering 10x longer life when drilling through:
✓ Reinforced Concrete (rebar up to 12mm)
✓ Fiberglass & Carbon Fiber (delamination-free edges)
✓ Ceramic Tiles (chip-resistant precision cuts)
✓ Abrasive Composites (stone/resin mixtures)
Electrofusion Bonding Process: 60% stronger grit retention than sintered alternatives
Variable Grit Geometry:
20/30 mesh for rapid stock removal
60/80 mesh for finish-quality edges
Progressive Tooth Angle: Self-cleaning design prevents material loading
Dual-Layer Steel Core:
Outer shell: Hardened 50HRC manganese steel
Inner sleeve: Vibration-damping chromium alloy
Heat-Dissipating Flutes: 3x cooling channels prevent HAZ (heat-affected zones)
Anti-Wear Markings: Laser-etched depth indicators remain visible through wear
