01｜Product Overview

This single recessed internal grinding wheel is made of premium first-grade abrasive materials, available in four abrasive types: white fused alumina, pink fused alumina, brown fused alumina and green silicon carbide. Designed for internal grinding machines with single recessed structure, it fits inner hole grinding working conditions. It features evenly distributed grains, excellent thermal conductivity, low heat generation during grinding, anti-clogging and anti-grain shedding. With sharp and stable cutting performance, high machining accuracy, low wear and long service life, it is suitable for precision inner hole grinding of various workpieces.
