In a nutshell
The right choise for
With the Hikoki 754349 hammer drill bit, you drill deep, large-diameter pass-throughs into reinforced concrete, masonry, and natural stone with complete control. The robust 4-cutter carbide head prevents binding and jamming when hitting rebar. An active centring point ensures accurate guidance without slipping, while generous flutes channel out drilling dust quickly to reduce heat build-up. Featuring a 45 mm diameter, a 570 mm overall length, and a 450 mm working length, this bit is built to bore clean holes for heavy pipe and conduit installations. It is compatible with all hammer drills using an SDS-max chuck.
