Product 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. Vacuum brazed diamond core drill bit usually have a single layer of diamonds, held by a touch durable nickle alloy. Vacuum brazed core bit 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 vacuum brazed core bit allows diamond particles to protrude from the bond matrix, providing a free, faster drilling action with minimum heat generation.

Features:

• Better removal rates and less thermal damage to the body

• hold simple and intricate forms through the entire working life

• Maximum exposure of diamond particle

• Faster drilling and more consistent performance
