1. Thinner diamond segment and thinner tube wall can easily reduce the resistance and increase the drilling speed (comparing with the assembly type) 2. SED bonding agent provide 20% higher cutting performance, particularly in difficult operating conditions. 3. Very fast cutting speed and low cutting pressure. 4. Different connection end for different drilling machine. 1-1/4"UNC 5. Especailly effective in drilling through reinforced concrete. 6. For dry and wet coring in reinforced concrete with very hard aggregate. 7. Also good for granite, marble, tile, glazed brick and other hard base materials with low abrasiveness. 8.Use with all sizes and grades of rebar. 9.Wet coring for over 18meters-25 meters coring length. 10.manufacturing art: Laser welded .
