THE DRILL BIT TO FORM THE PATTERN TO DIAMOND PARTICLES

摘要

PURPOSE: A drill bit for forming patterns using diamond particles is provided to improve cutting efficiency and accuracy by maintaining cutting conditions. CONSTITUTION: A drill bit for forming patterns using diamond particles comprises a hollow core(10) and segments(20). The segments are manufactured by heating and sintering diamond particles(21) and a metal mixture(22) in a heating furnace with a temperature of 800-1000degrees and are welded to the end of the core. The metal mixture is formed by mixing metal powder with a binder. The patterns of the diamond particles are concentrated on the rotation ends(20a) of the segments.
