Diamond Core Drill Bit Concrete Rated 1 1/4" UNC Fittings 140mm Diameter x 450mm Length
Rated to cut reinforced concrete.
The lengths given are the internal core depth.
Best performance and wear in reinforced concrete but will also cut ‘most’ other materials either more slowly
1 ¼” UNC fitting is the international standard used on most diamond core drill machines while some smaller hand held machines may be fitted with ½” BSP threaded spindle.
When drilling concrete it is important to deliver water internally to the diamond segments which keeps them cool and removes the debris.
To prevent damage to diamond segments it is important that the rig mounted core drill machine is bolted firmly to the floor or wall so that absolutely no rocking or vibrations can occur.
Machine rig bases are supplied with four ‘levelling’ bolts so that when all four are wound down into contact with the surface, vibration can be fully prevented and the centre U slot is for anchoring the rig base down onto the surface.
Read core drill machine user manuals carefully.
