Dymaxion Diamond Core Drill Bits For Reinforced Concrete in Core Drilling Machines CCSU Series Size:110mm x 450mm Reduces friction for longer toolFeatures Optimised for cutting reinforced concrete. Will cut most other materials with a possible decrease in cutting speed and increase in bit wear. Diamond core drills and hole saws require the use of proper lubrication, correct drill speed and proper pressure. 1. 1 4" UNC is the international standard fitment used on most diamond core drill machines. When core drilling in concrete it is important to deliver water internally to the cutting edge to
