OVERVIEW

High-Performance General Purpose Sanding

The Walter 15C503V Coolcut Sanding Disc is engineered to deliver exceptional versatility and superior performance in industrial environments. Designed primarily for steel applications, this 5-inch resin fibre disc utilizes premium aluminum oxide grains to achieve a high removal rate while maintaining a consistent finish. The 36 grit composition makes it an ideal choice for aggressive stock removal, leveling welds, and breaking down heavy surface contaminants.

Walter Surface Technologies manufactures the Coolcut line using a precision electrostatic process that orients the abrasive grains for maximum cutting efficiency. This is paired with a robust fibre backing that provides the necessary rigidity for heavy-pressure applications without compromising safety or durability. The specialized bonding agents used in the Coolcut series promote a cool cutting action, significantly reducing the risk of heat buildup, warping, or discoloration on the workpiece—a critical factor when working with heat-sensitive metals or thin-gauge steel.

This pack contains five discs, making it a convenient option for maintenance departments, fabrication shops, and MRO tool cribs. Whether used for beveling, blending, or general surface cleaning, the Coolcut disc offers a reliable balance of speed and longevity. It requires a compatible backing pad for operation on angle grinders, ensuring the disc conforms properly to the work surface for optimal results.

Key Industrial Benefits

  • Cost-Effective Performance: Delivers a high removal rate at an economical price point for general purpose tasks.
  • Thermal Management: Advanced bonding technology dissipates heat to protect the base material.
  • Durability: Tough fibre backing withstands the rigors of edge grinding and heavy weld removal.

FAQ

The Coolcut disc is designed primarily for general purpose sanding on steel surfaces.

Yes, resin fibre discs like the 15C503V require a compatible backing pad (typically a turbo or rubber pad) for use on an angle grinder.

This specific disc is 36 grit, which is a coarse grit suitable for aggressive material removal.

This product (SKU 15C503V) is sold as a package of 5 sanding discs.

While it can be used on stainless, Walter offers specific products like the Topcut or Coolcut XX series that may offer better performance and longevity on stainless steel. The standard Coolcut is optimized for mild steel.

Standard 5-inch resin fibre discs typically feature a 7/8" arbor hole to fit standard angle grinder backing pads.

Aluminum oxide abrasives can load up quickly on soft metals like aluminum. For aluminum, a disc with a specialized coating or zirconia/ceramic grain is usually recommended to prevent clogging.

Always check the disc label for the specific Max RPM. Generally, 5-inch fibre discs are rated for use on standard angle grinders, often around 10,000 to 12,000 RPM, but safety compliance requires verifying the printed rating.
