The CGW 42112 4" x 3/8"-24 Type 27 40-Grit Zirconia Flap Disc is designed for aggressive material removal on steel surfaces. This wheel combines premium zirconia alumina grain with a durable poly/cotton backing to balance stock removal with a smoother finish. Zirconia concentration enhances grinding efficiency, helping users achieve faster material removal compared with typical aluminum oxide blends, while the active grinding aid supports cooler cutting under light pressure.
Built for demanding applications, the Type 27 profile optimizes edge contact and grinding angles for flat and contoured surfaces alike. The 4" diameter and 3/8"-24 arbor size provide compatibility with standard angle grinders. The disc is configured for high RPM operation, listed at up to 15,300 RPM, making it suitable for heavy-duty use where rapid stock removal is required. The plate assembly and abrasive construction are intended to withstand rigorous cycles common in fabrication, maintenance, and metalworking settings.
For practical use, apply with even pressure and use appropriate PPE to manage airborne particulates and debris. Maintain a consistent grinding approach to maximize performance and disc life, and monitor wear to determine replacement timing. This product ships in a box of ten individual discs, facilitating easy stocking and replacement in busy shop environments.
