Description

Featrue ***** diamond segment and thinner tube wall can easily reduce the resistance and increase the drilling speed (compare with the assembly type) 2.SED bonding agent provide *0% 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. ***** effective in drilling through reinfored concrete. Diamond Core Drill Bits, also know as Diamond Hole Saws, are used to drill glass, ceramics, porcelain, ceramic and porcelain tile, limestone, slate, marble, granite, stone, and fiberglass. Just add water for lubrication. Core drill bits have a hollow center and cut a circle in the material to create a hole. This results in a hole the size of the drill and a smaller "plug" or "core" which comes from the center. Diamond core drill bits are available in sizes from 5/*4" to 4" (outside diameter). The metric manufactured size of each diamond drill bit is also shown below (mm), along with the exact inch measurement. Diamond drill bits are easy to use, however, there are many special techniques which are different from standard steel-bit drilling. Diamond drill bit usage can also vary depending upon the diamond drill bit type and the specific manufacturer. To assist our customers, we have compiled a detailed section.
