Extra-Large 30 mm Solid Carbide Tip: Engineered high-grade carbide cutting head bonded at high brazing temperatures delivers aggressive aggregate destruction and prolonged edge life.
Positive Self-Centering Point Geometry: Sharp chisel pilot center bites immediately into dense stone and concrete surfaces, preventing tool skating and producing true, round anchor holes.
Accelerated 4-Flute Waste Spiral: Deep multi-channel flutes rapidly extract pulverized masonry dust and slurry from the borehole, minimizing thermal build-up and preventing flute packing.
Reinforced Heavy-Gauge Core: Thickened alloy steel core absorbs extreme torsional shock loads, dampens vibration feedback to the operator, and resists bending fatigue.
Standard 10 mm SDS Plus Fitment: Fully compatible with all 2kg to 4kg SDS Plus rotary hammer drills across Nepal, providing direct slip-free torque and impact energy transfer.
