-
Micro-Grain Tungsten Carbide Tips (TCT): Precision-brazed carbide cutting teeth resist high thermal loads and abrasion, staying razor-sharp through dense alloy steel and stainless plates.
-
Perimeter Core Cutting Efficiency: Annular geometry removes material solely at the hole perimeter, significantly reducing motor strain, power consumption, and drilling time compared to twist bits.
-
Accurate 22 mm Diameter x 35 mm Depth: Delivers precise 22 mm holes up to 35 mm deep with smooth walls, accurate tolerances, and clean burr-free entry and exit profiles.
-
Standard Industrial Weldon Shank: Compatible with standard 19.05 mm (3/4") Weldon chucks across major magnetic drills, ensuring rigid bit clamping and positive drive torque.
-
Optimized Multi-Cut Tooth Architecture: Alternating internal, external, and intermediate cutting edges distribute mechanical load evenly to prevent teeth chipping under heavy feed pressures on jobsites in Nepal.
