Concrete Core Drill Bit - X301 Zz Turbo - Hard Concrete

Designed for plumbers and electricians drilling clean holes through cured structural concrete and reinforced foundations. The X301 Zz Turbo features a .155-inch wall thickness engineered to handle the demands of hard concrete applications where standard bits burn out. Turbo segment design provides faster cutting speed and efficient debris removal in dense aggregate mixes. The 3-1/2 inch diameter with 1 1/4-7 arbor fits standard core drill rigs used on commercial and industrial job sites. Diamond Vantage manufactures this bit with segments formulated specifically for hard concrete conditions that slow down softer-rated alternatives. Built for drilling contractors and mechanical trades running multiple penetrations daily through hardened slabs and walls.
