Kimdrill DTH bits By Kimdrill Industrial Co. Ltd, China

Product Description

Kimdrill DTH bits (down the hole bits) are hot pressed and undergo a combination of heat treatments, thus guaranteeing the good quality and longevity. The diameters range from 60mm to 700mm. The shanks can be Cop series, like COP32, COP34, cop44, cop54, cop64, cop84. DHD series, like DHD3.5, DHD350, DHD340, DHD360, DHD380. QL series, like QL40, QL60.QL80. SD series, SD4, SD5, SD6, SD8, CIR series, like CIR65, CIR70, CIR80, CIR 90, CIR110, CIR110W, CIR150, CIR170, CIR200W, and so on. We can design and manufacture according to customer's request, such as flat face, convex face, concave face, drop center face, spherical s, ballistic s, spike s, conical s.
