Resin Bond Diamond & CBN Spiral Grinding Wheel for Tool Edge & Thread Grinding

Heavy-Duty Spiral Diamond/CBN Wheel for HSS/Carbide Tool Sharpening & Thread Grinding

Product Overview

This resin-bond spiral grinding wheel is engineered for heavy-duty industrial tool grinding and thread grinding. It combines high-performance diamond (for carbide) or CBN (for HSS) abrasives with a resin bond, delivering sharp cutting action, excellent heat resistance, and long service life. The spiral groove design ensures efficient chip removal and cooling, preventing workpiece burn during continuous grinding. Ideal for mass production and high-precision tool resharpening.
