Description

This dry concrete core bit is specially developed for dry drilling into hard materials such as concrete, brick walls, and stone. It is manufactured by high-frequency welding premium diamond segments onto a tough steel body, and fitted with a carbide-tipped pilot drill for fast drilling and accurate positioning. The universal M16 threaded connection allows direct mounting onto an angle grinder or extension rod, while the supplied pilot drill comes with both SDS and hex shank adapters, making it fully compatible with SDS-plus rotary hammers, impact drills, and standard hand drills. Designed for dry operation with no water required, it delivers clean hole edges, smooth hole walls, and efficient dust evacuation without core binding — making it a highly efficient and reliable choice for plumbing and electrical installations, air-conditioner vent drilling, pipe routing, and switch box cut-outs.

Key Features

• Dry Drilling, No Water, High Efficiency
  No cooling water needed — works dry. Sharp diamond teeth cut into concrete quickly, eliminating messy slurry and keeping the job site clean.
• M16 Thread + SDS/HEX Dual Compatibility
  The core bit body features a universal M16 thread. Supplied with a carbide pilot drill fitted with SDS and hex shank adapters, it fits rotary hammers, impact drills, and standard drills — one tool for multiple applications.
• Wear-Resistant Diamond Teeth, Anti-Chipping
  High-grade diamond teeth are firmly bonded. They withstand high temperatures during dry drilling, resist chipping, and significantly extend service life.
• Precise Positioning, No Walking
  The carbide pilot drill provides stable centering with an accurate, slip-free start, ensuring precise hole location and a clean hole edge.
• Smooth Chip Removal and Heat Dissipation, No Clogging
  Optimized cutting edges and flutes allow fast dust ejection and timely heat dissipation, preventing core binding and jamming for smoother continuous operation.
