CGW 43860 4-1/2" X 5/8"-11 Type 27 36-Grit XL PSG Ceramic Extreme II Flap Disc

The CGW 43860 flap disc is a 4-1/2 inch diameter, 5/8-11 threaded arbor Type 27 configuration designed for aggressive material removal on angle grinders. This disc uses PSG Ceramic grain, which is engineered to stay sharper longer, delivering a cooler and faster cut with improved durability compared to conventional ceramic, alumina, or zirconia discs. The 36-grit sizing provides coarse material removal suitable for shaping, deburring, and blending on metal surfaces, while the Type 27 face angle is optimized for contouring and flat-face grinding tasks. Packaging includes ten discs per box, with each disc intended for individual use, supporting organized stocking and efficient job-site rotation.

The construction emphasizes longevity and versatility. PSG Ceramic grains are designed to penetrate efficiently while resisting glazing, helping maintain cutting performance across extended work sessions. The combination of a 4-1/2" diameter and 5/8"-11 arbor makes this disc compatible with common right-angle grinders found on maintenance and repair work, metal fabrication, and facility maintenance tasks. The product identity and specifications indicate a balance between aggressive material removal and control, suitable for preparing welds, deburring sharp edges, and smoothing rough surfaces in a variety of metalworking applications. Maintain consistent speed and avoid overheating by working with light-to-moderate pressure and allowing the disc to do the cutting.

For best results, verify your grinder’s arbor compatibility (5/8-11) and ensure the Type 27 disc orientation aligns with your grinding angle. As with all flap discs, inspect for wear and replace when the backing or grains show signs of damage or significant thinning. The box quantity helps ensure you have spare discs on hand to minimize downtime on maintenance and fabrication tasks.
