Concrete Core Drill Bit - X301 Zz Turbo - Hard Concrete

Plumbing and electrical contractors drilling anchor bolt holes through hardened concrete slabs will find this 1-3/4 inch turbo core bit handles the toughest material. The X301 Zz Turbo design from Diamond Vantage cuts through hard concrete where standard bits bog down or burn out. This bit measures 1-3/4 x .125 x 1 1/4-7 and features a turbo segment pattern that clears dust faster and maintains cutting speed in dense aggregate mixes. The arbor fits standard core drill rigs without adapters. Segments are laser-welded to prevent loss during extended cutting in rebar-heavy pours. Designed for contractors running multiple holes per day in commercial and industrial settings where concrete strength exceeds 4,000 PSI and downtime costs money.
