Diamond Core Drill Bit for Concrete 68x450mm 1 1/4" UNC
The diameter of 68 mm is the standard for installation and electrical back boxes, which is why this core bit is the most frequently used size in electrical and installation work. The hole is clean and perfectly round and the wall around it remains undamaged, which considerably reduces subsequent plastering repairs.
The bit body has a length of 450 mm, so even a thicker load-bearing wall can be drilled through in one go, for example when passing a cable or pipe from room to room. The segments are laser brazed and can also handle drilling in reinforced concrete, where working with water cooling is recommended. Mounting is provided by a 1 1/4" UNC female thread compatible with core drills.
Technical data:
Outer diameter: 68 mm
Overall length: 450 mm
Mounting thread: 1 1/4" UNC (female)
Segment type: diamond, laser welded
Drilling mode: wet (recommended for reinforced concrete) and dry
Weight: 1.88 kg
