ChinShine 3 parts diamond core drill bits are ideal for drilling holes in concrete and reinforced concrete applications. A key feature provided on all wet bits is the precision threaded cap-to-tube system. With our unique top threaded bits, we have virtually eliminated lateral runout at the drilling face of the core bit. This allows the bit to spin more precisely without a loping effect that commonly occurs due to an uneven cap to tube weld. More precise running bits mean quicker penetration and drilling while also decreasing segment side wear and drag. Bits below 2 equipped with 5/8-11 thread and bits 2 above equipped with 1-1/4-7 thread. 

Chinshine diamond core drill bits and bits segments are made of top quality diamond and cobalt porder.It provides a high efficiency and stable drilling.And the zigzag diamond core bits segments make your drilling work much easier. We separate the drill bits into 3 or 4 parts, this make it easier to change the drill bits segments, adopt your drill bits to different drilling machine and enhance the drilling depth.
