Cross-Head 4-Cutter Solid Carbide Geometry: Four symmetrical cutting edges ensure smooth, non-binding drilling through tough concrete and rebar mesh, eliminating sudden bit seizure.
Precise Circular Anchor Holes: Creates clean, true-diameter cylindrical holes to guarantee maximum holding strength and reliable mechanical expansion for anchor bolts.
Four-Flute High-Velocity Dust Evacuation: Multi-channel spiral flute design clears crushed debris rapidly from the borehole, keeping running temperatures cool and extending cutting life.
Heat-Treated Alloy Steel Core: Reinforced metal body absorbs high-frequency electro-pneumatic impacts without bending, shank distortion, or fatigue snapping.
Universal SDS Plus Tool Fitting: Slotted drive shank fits securely into all standard SDS Plus rotary hammers, delivering 100% impact transfer across construction sites in Nepal.
