- [Industrial Welded Build] 4" diamond core drill bit made with premium diamond grit and high-frequency welding to keep segments locked under load. Turbo rim maintains continuous contact so the bit keeps “biting” instead of skating, helping you core faster through dense masonry while extending working life versus general-purpose diamond drill bits.
- [4" Core Size + 1-1/4"-71 Fit] 4" diameter with a 18" overall length, built as a core drill bit with an industry-standard 1-1/4"-71 thread for most core drill rigs and common rotary coring setups. The long barrel supports through-wall penetrations and clean pass-through holes for HVAC sleeves, plumbing lines, and conduit runs.
- [Straight Tracking, Less Wobble] Concentric axis design plus precision tooth geometry helps the bit run true, reducing vibration and “walking” at startup. Side slots assist chip removal and heat relief during dry coring, which lowers binding and keeps the cut smoother, important when you’re holding the tool overhead or working on finished surfaces.
- [Rotary Only, Dry-Coring Technique] Designed for rotary use only—do not use hammer mode. Start at a light angle to score the surface, then bring vertical once the groove is established; keep steady RPM and moderate feed pressure so the rim stays cutting instead of overheating. When you need a round penetration like a diamond hole concrete hole saw, this bit cores a clean opening for HVAC and plumbing work.
- [Material Range] Engineered for brick, block, mortar, cinder block, and low-to-medium reinforced concrete. When drilling into concrete with rebar, the diamond segments keep cutting through the transition from concrete to steel with less stalling. Works as concrete drill bit drill bits for coring a clean plug instead of grinding the material into loose debris.
