HSS Center Drill Bits

HSS Center Drill Bits

We are a Manufacturer of HSS Center Drill Bits in India, suitable for drilling the holes in many materials such as pebbles, stones, glass, etc. They can also work on softer materials such as drilling hole metals, fiberglass, etc. It is a drill bit with high sharpness and outstanding durability. DIC HSS Center Drill Bits are ideal for accurately drilling a center hole in preparation for a larger drill bit to be used. Center Drill Bits are ideally designed to drill a small diameter pilot hole followed by a 60-degree countersink that provides a bearing surface for a 60-degree point of the lathe center.

Moreover, these are also used extensively with the milling machine to start holes accurately. We have a solution for everything, whether standard or non-standard.
