Concrete Core Drill Bit - X301 Zz Turbo - Hard Concrete

Electrical contractors drilling conduit holes through cured foundation walls will find this 1-1/8 inch diameter core bit handles hard concrete without hesitation. The Zz Turbo segment design from Diamond Vantage cuts clean holes with a 5/8-11 thread mount that fits standard angle grinders and core drill rigs. The .125-inch wall thickness provides durability when working through aggregate-heavy mixes and reinforced sections. This X301 model delivers consistent performance in high-strength concrete where standard bits bog down or glaze over. The turbo segments maintain cutting speed in dense material while clearing dust effectively from the hole. Built for electricians, plumbers, and mechanical contractors who need reliable penetrations in commercial and industrial applications.
