Concrete Core Drill Bit - X301 Zz Turbo - Hard Concrete

Professional plumbers and electricians drilling precise holes through cured concrete slabs for conduit and pipe runs depend on tools that won't quit mid-job. This Diamond Vantage X301 Zz Turbo core bit measures 2-1/2 inches in diameter with a .155-inch segment thickness and 1 1/4-7 thread connection, engineered specifically for hard concrete applications where standard bits burn out. The turbo segment design increases cutting speed while evacuating slurry efficiently, reducing binding in deep holes. The reinforced steel core body maintains stability during operation, preventing wobble that damages hole quality. Segments are laser-welded to handle the heat and vibration of continuous drilling in aggregate-heavy mixes. Built for mechanical contractors and utility installers running multiple penetrations per day in commercial and industrial construction.
