As a Ceramic Cut Off Wheel in Black tone with non reinforced Type 1 construction, it features precision shaped grain for clean, burr free cuts. This 4 Inch Cut Off Wheel runs up to 25,465 RPM, making it an ideal metal cutting wheel for steel, stainless steel, and other alloys. Its ceramic aluminum oxide formulation extends wheel life and minimizes heat buildup. Compatible with standard angle grinders, it mounts and releases quickly to keep your workflow moving.
Product Features and Benefits
Engineered Precision Shaped Grain
Precision shaped grain continuously fractures to expose fresh cutting edges, maximizing lifespan and cut rate. Ideal for fast, clean cuts in stainless steel, carbon steel, and other tough metals.
High Performance Ceramic Construction
Non reinforced ceramic abrasives provide superior hardness and fracture resistance over conventional wheels. The wheel maintains metal cutting efficiency under load, reducing tool changes and downtime.
Optimal Size & Compatibility
4 inch cut off wheel, ¼ inch arbor hole, and 1/32 thickness fit most angle grinders up to 25,465 RPM. Thin profile offers access in tight spaces and precise cutoff control.
