RUKO HAB-SDS 19,0x450x400mm punta per martello SDS-max per calcestruzzo e muratura

Drilling large-diameter holes in reinforced concrete or masonry with a standard rotary hammer can be slow and punishing on both the tool and the bit. The RUKO HAB-SDS 19.0x450x400mm hammer drill bit solves this with an SDS-max shank and a robust 4-cutter tungsten carbide head that maintains speed and accuracy in demanding materials.

Who is it for

Professional contractors, electricians, and plumbers who regularly anchor heavy loads, install rebar, or core through concrete and natural stone. It fits any rotary hammer with an SDS-max chuck.

Main features

• SDS-max shank for secure, tool-free bit changes and efficient power transfer.
• 19.0 mm diameter with 450 mm overall length and 400 mm working length.
• 4-cutter tungsten carbide tip with centering point for precise spot drilling and reduced wandering.
• Optimized KVS flute design for fast dust removal and cooler operation.
• High-grade steel body with corrosion-resistant finish.
• PGM-certified for quality in masonry drilling.

Tips

Use a rotary hammer in hammer drilling mode only, never in rotation-only mode. Apply steady pressure and periodically withdraw the bit to clear dust from the hole. For reinforced concrete, reduce feed pressure when you encounter rebar to avoid chipping the carbide edges.
