Reliable 500W Continuous Power Core: Powered by an optimized 500W electric motor designed to maintain stable rotational torque and thermal durability during prolonged drilling cycles.
High-Torque 0–1300 RPM Speed Range: Operates at a controlled 0–1300 rpm variable speed, delivering higher turning torque to prevent bit stalling when boring dense masonry or concrete.
Heavy-Duty 13mm (1/2") Keyed Chuck: Equipped with a rugged three-jaw keyed mechanical chuck that locks drill bit shanks tightly against rotational slippage under heavy percussion loads.
Dedicated 10mm Concrete Boring Capacity: Engineered specifically for medium-duty tasks, cleanly penetrating up to 10mm in solid concrete, brickwork, and aggregate masonry blocks.
Ergonomic Control & Continuous Operation: Formatted with a 360° adjustable auxiliary side handle and a continuous lock-on trigger switch to reduce user fatigue across jobs in Nepal.
