Diamond Point Chisel: The Ultimate Guide for Industrial Buyers and Suppliers

Introduction to Diamond Point Chisels

A diamond point chisel is a specialized hand tool or industrial bit featuring a sharp, pyramidal, or conical tip made from or coated with industrial-grade diamond particles. Unlike standard steel chisels, the diamond point delivers extreme hardness and abrasion resistance, making it ideal for cutting, scoring, engraving, and shaping hard, brittle materials such as glass, ceramic, stone, concrete, and hardened steel. These chisels are widely used in construction, masonry, jewelry making, and precision manufacturing. The diamond tip is typically bonded to a steel shank through sintering, electroplating, or vacuum brazing, ensuring durability under high-impact or high-friction conditions.
