Engineered for professional concrete coring, this wet-only diamond core drill bit is built to deliver fast penetration, clean round holes, and stable tool life in concrete, masonry, hard brick, and selected stone applications. Continuous water cooling is required to control heat and slurry removal, and wet methods are widely recognized for reducing airborne dust during drilling tasks. Choose from M22, 1-1/4" UNC (7 TPI), or 1/2" GAS (G1/2) threads to match mainstream hand-held or rig-mounted coring systems.

Universal for dry or wet cutting. Available for cutting tiles, ceramics and marble... The hot pressing process ensures a longer service life of the saw blade. 

Concrete driller is a kind of efficient and precise drilling equipment,which is widely used in construction,decoration,industry and other field. Electric core drill mainly cuts concrete, stone, tiles and other materials through the diamond particles on the drill bit, thus realizing precise hole cutting. Core drill is named for its working principle, tie. cooing the drill bit by water during the drilling process,which reduces friction and head generation,thus prolonging the service life of the drill bit and effectively reducing dust and noise solution.Core drilling machine are smooth cutting surface, non-destructive structure, high drilling accuracy,especially suitable for the construction of critical parts such as,floors and Ceramic tile.

The SENMINE AC Electric Ring Saw is a professional-grade wall cutting machine built for precision, power, and endurance. With a brushless motor, high-frequency transmission, and an advanced wet cutting system, it is ideal for deep penetration into reinforced concrete, red bricks, lightweight blocks, and cement floors. Whether you're opening elevator shafts, windows, doorways, or making cuts in staircases, the AC ring saw delivers clean, efficient results with minimal maintenance.
Its compact, handheld design makes it ideal for tight working spaces, while its 5000W motor ensures reliable performance even under industrial conditions.
