The 21105 Cut‑Off Wheel is built for metalworkers who require fast, precise cutting performance with exceptional durability. Featuring a high‑performance ceramic abrasive grain, this Type 1 wheel delivers superior cutting speed, reduced heat buildup, and extended life compared to standard cutting wheels. Its 4‑1/2‑inch diameter and ultra‑thin .045‑inch profile provide smooth, efficient cutting with minimal burr formation. The 7/8‑inch arbor allows compatibility with a wide range of angle grinders frequently used in fabrication, maintenance, and industrial environments.
