Industrial-Grade Solid Construction
Forged from high-carbon steel with diamond-coated threading for extreme durability. Thickened core (20% wider than standard rods) resists bending under heavy torque.
Precision Multi-Angle Adjustability
360° swivel head with reinforced brass bearings enables flawless wall/ceiling drilling in tight spaces. No-slip hexagonal grip ensures stable force transfer.
Universal Heavy-Duty Applications
Designed for masonry drilling (concrete/brick), soil sampling, and HVAC installations. Compatible with most rotary hammer drills (SDS-Plus/SDS-Max).
Bulk-Optimized for Contractors
Pre-packaged in corrosion-resistant PVC sleeves. Pallet-ready for large-scale job sites. Wholesale pricing unlocks 35% savings on 50+ units.
Engineered for Speed & Safety
Heat-treated tip prevents mushrooming during prolonged use. Laser-etched depth markings enable millimeter-accurate drilling.
