Diamond Core Bit

1. Premium diamond segment formulation balances cutting speed and service life, delivering stable performance on reinforced concrete and natural stone.
2. Thick seamless steel tube body resists deformation under heavy load, maintains excellent concentricity for straight, accurate holes.
3. Optimized segment geometry accelerates debris removal, reduces friction and prevents bit jamming during continuous drilling.
4. Flexible connection structure compatible with handheld water drills and impact drills; custom OD, segment length and thread available.

1. Diameter by hole size: BD-DCB018 to BD-DCB063 (18-63mm) for pipe and conduit holes; BD-DCB071 to BD-DCB127 (71-127mm) for HVAC and drainage holes; BD-DCB140 to BD-DCB350 (140-350mm) for large vent, sewer and pipeline holes requiring rig-mounted drills.
2. Dry and wet versatility: supports both dry and wet drilling—use wet for reinforced concrete and deep holes to cool segments, dry for on-site renovation where water is unavailable; the high-hardness diamond crown resists wear on concrete, walls, marble and stone.
3. Equipment matching: the 450mm overall length reaches through thick walls and slabs; connection type customizable to match handheld core drills, wet core drill rigs and impact drills; segment count scales from 2 on small diameters to 23 on 350mm for balanced load distribution.
4. Drilling result: fast drilling speed with stable connection and low vibration, leaving a clean hole wall ready for pipe installation; the wear-resistant segments deliver long service life across concrete, masonry and stone applications.

Multiple bore diameter and tooth count options available to match your cutting machine.
