04C312 - Walter Coolcut XX 3-Inch Twist-On Sanding Disc 120 Grit

High-Performance Ceramic Sanding Disc

The Walter 04C312 Coolcut XX™ is a premium 3-inch sanding disc designed for industrial metalworking applications requiring both speed and precision. Engineered with Walter's exclusive Cyclone™ Technology, this disc features a high-performance ceramic abrasive grain blend that stays sharp longer than conventional aluminum oxide or zirconia discs. The 120 grit rating makes it an excellent choice for finishing stages, blending welds, and preparing surfaces for painting or polishing.

Efficiency is at the core of the Coolcut XX design. The Twist-on fastening system ensures compatibility with standard backing pads, allowing operators to switch between grits or product types in seconds. This quick-change capability significantly reduces downtime in multi-step finishing processes. The ceramic grain structure is self-sharpening, fracturing under pressure to reveal fresh cutting edges, which maintains a consistent removal rate throughout the life of the disc. This longevity translates to fewer disc changes and lower overall consumable costs for high-volume fabrication shops.

Designed for versatility, the 04C312 is effective on a wide range of materials, including mild steel, stainless steel, and aluminum. Its cool cutting action helps prevent thermal damage, such as warping or blueing, which is critical when working on thin-gauge metals or heat-sensitive alloys. The disc's durability and aggressive cut make it a superior alternative to standard fiber discs for small-area grinding and contour work.
