OVERVIEW

Walter 15C712 Coolcut 7-Inch Resin Fibre Sanding Disc

The Walter 15C712 Coolcut™ Sanding Disc is a high-performance abrasive consumable designed for industrial metalworking applications. Engineered by Walter Surface Technologies, this 7-inch disc features a fine 120 grit, making it an excellent choice for finishing operations, surface preparation, and light material removal on steel and ferrous metals. The Coolcut line is renowned for its economic value while maintaining the rigorous quality standards expected by professional fabricators.

Constructed with a premium quality fibre backing, these discs are built to withstand the mechanical stresses of angle grinding operations. The manufacturing process utilizes an advanced electrostatic grain distribution method. This technique ensures that the aluminum oxide grains are oriented vertically, exposing the sharpest cutting edges to the workpiece. This results in a significantly higher removal rate and a more consistent surface finish compared to randomly oriented abrasive discs. The 120 grit specification is particularly effective for the final stages of sanding, where smoothing out scratches from coarser grits or preparing a surface for painting and coating is required.

Durability is a key feature of the 15C712. The resin bonding system securely anchors the abrasive grains to the fibre backing, preventing premature shedding and extending the life of the disc. This product is designed to run cool, reducing the risk of thermal discoloration or warping on thin gauge metals. It requires a compatible backing pad (typically a turbo or standard rubber pad) for operation on right-angle grinders. With a maximum speed rating of 8,600 RPM, it is compatible with standard 7-inch industrial grinders. Whether used for general maintenance, fabrication, or automotive bodywork, the Walter Coolcut disc delivers reliable, consistent results.

FAQ

The Walter 15C712 Coolcut disc has a grit rating of 120, which is considered fine and suitable for finishing and cleaning.

Yes, resin fibre discs like the 15C712 require a backing pad (typically a rubber or turbo pad) to support the disc on the angle grinder.

This disc is 7 inches in diameter with a standard 7/8-inch arbor hole.

While it can be used on stainless steel, the Coolcut line is primarily designed for general purpose use on steel. For dedicated stainless steel work, Walter's Topcut or Coolcut XX lines might offer better performance.

The maximum safe operating speed for this 7-inch disc is typically 8,600 RPM. Always check the disc label to confirm.

These discs are typically sold in packages of 25.

No, 120 grit is a fine abrasive meant for finishing, cleaning, and light blending. For heavy stock removal, you should start with a coarser grit like 36 or 50.
