Diamond Core Drill Bit CD300

MESA DIAMOND CORE DRILL BIT CD300 – Built for Hard Coring

The CD300 is a wet diamond core bit built for demanding coring work in concrete, reinforced concrete, masonry and asphalt. It is made for contractors who core hard, aggregate-heavy material on a daily basis and need a bit that holds its cutting speed instead of glazing over.

The CD300 carries flat-top segments with grooved side faces. The continuous flat cutting face puts the full segment width in contact with the material, which keeps the bit tracking straight through hard concrete and produces a clean, accurate bore wall. Segments are laser welded to a premium steel body for a joint that survives heavy jobsite use.

Select cutting diameter, drilling length and connection end separately to match your rig and your hole.
