Core bits Description:

Diamond Core Drill Bit is a cylinder used for plunge cutting out materials. It is composed of a heat treated steel core and the working part which consists of diamond and metal powder. Diamond core drill bit usually have a single layer of diamonds, held by a touch durable nickle alloy. Core bits are able to retain their original shape and dimensions through their working life. Unlike sintered (metal bond) where diamond particles are buried in bond and held together by metal binder deep inside. The core bit allows diamond particles to protrude from the bond matrix, providing a free, faster drilling action with minimum heat generation.

For diamond drill bit diameters 10mm to 38mm we use high quality 10mm high quality crown (ring) diamond segments – This helps for an easy start-up when hand held drilling.

For core bits diameters 40mm to 500mm we use high quality 10mm high diamond segments with castellated tips to insure an easy start-up and fast opening of the segment.Usually customers will choosing the thread of 1-1/4-7.
