04C156 - Walter Coolcut XX 1.5 Inch Ceramic Quick-Change Disc Grit 60

High-Performance Ceramic Abrasive for Precision Blending

The Walter Twist Coolcut XX 1-1/2" Sanding Disc (SKU: 04C156) represents the pinnacle of small-diameter abrasive technology, engineered specifically for industrial environments requiring maximum material removal rates and superior surface finish consistency. At the core of this abrasive is Walter's proprietary Cyclone™ Technology, a high-performance ceramic abrasive grain blend. Unlike conventional aluminum oxide or zirconia grains, these ceramic structures are engineered to micro-fracture under pressure, continuously exposing fresh, sharp cutting edges. This self-sharpening mechanism ensures that the disc maintains a consistent cut rate throughout its entire lifecycle, rather than dulling rapidly after the initial contact.

Thermal management is a critical factor in abrasive performance, particularly when working with heat-sensitive alloys like stainless steel and aluminum. The Coolcut XX formulation incorporates active grinding aids that significantly reduce friction at the interface between the abrasive and the workpiece. This results in a cooler cutting action that mitigates the risk of heat discoloration, warping, or metallurgical changes in the base material. For MRO professionals and fabricators, this means less time spent on rework and post-weld cleanup, ensuring that the structural integrity and aesthetic quality of the part are preserved.

The "Twist" nomenclature refers to the disc's integral quick-change attachment system, which is fully compatible with standard Type R backing pads. This mechanical locking mechanism ensures a secure, vibration-free connection that can withstand the high rotational speeds required for effective small-diameter grinding. The 1-1/2 inch diameter is ideal for accessing tight spaces, intricate contours, and confined corners where larger 4.5-inch or 5-inch angle grinders cannot reach. With a coarse 60 grit rating, this specific disc is optimized for medium-to-heavy stock removal, leveling welds, and blending parting lines, offering a perfect balance between aggression and finish quality.

Durability is a hallmark of the Walter Surface Technologies lineup. The Coolcut XX discs boast the longest lifespan in the industry for their category, directly translating to reduced consumable costs and lower inventory requirements. By minimizing the frequency of disc changes, operators can maintain momentum and focus on the task at hand, driving overall operational efficiency. Whether utilized in aerospace maintenance, automotive fabrication, or general metalworking, the 04C156 delivers reliable, industrial-grade performance.
