OVERVIEW

High-Performance 7" Sanding Discs for Welders

Upgrade your metal finishing game with the Walter 15C705 Coolcut Sanding Disc. Designed specifically for the rigors of welding and fabrication, this 7-inch disc features a coarse 50 grit that makes short work of light weld seams, spatter, and surface imperfections. When you need to transition from grinding to finishing, or simply need to clean up a steel plate, the Coolcut series delivers the aggressive bite you need with the smooth finish you want.

Keep Your Workpiece Cool

Heat is the enemy of a good finish. Walter's Coolcut technology is formulated to reduce friction and heat buildup during the sanding process. This is critical when working on heat-sensitive projects or when trying to avoid the "blueing" effect on steel. The result is a cleaner surface that requires less rework, saving you time and money on every job.

Built Tough for Daily Use

Welders know that cheap discs fall apart under pressure. The 15C705 is built on a heavy-duty vulcanized fibre backing that stands up to the torque and heat of angle grinding. The electrostatically applied aluminum oxide grains stay sharp longer, providing a consistent cut rate throughout the life of the disc. This means fewer disc changes and more time spent making sparks.

Perfect for general purpose sanding on steel, these discs are a staple for any welding rig or shop cabinet. Pair them with a high-quality backing pad for optimal performance and safety. Whether you are smoothing out a repair or prepping a new fabrication for paint, trust Walter Coolcut discs to deliver professional results every time.

FAQ

The Walter Coolcut 15C705 uses premium aluminum oxide grain, which is ideal for general purpose sanding on steel.

Yes, resin fibre discs like the 15C705 require a compatible backing pad (typically hard rubber or plastic) to support the disc during use.

While specific ratings should always be checked on the disc itself, standard 7-inch fibre discs are typically rated for around 8,600 RPM.

While it can be used on stainless steel, Coolcut is optimized for general purpose steel. For dedicated stainless steel work, Walter offers other specialized lines like Topcut or Coolcut XX.

It refers to a manufacturing process where an electric field aligns the abrasive grains so their sharpest points face outward, resulting in a more aggressive and consistent cut.

50 grit is considered a medium-coarse grit. It is aggressive enough for light weld removal but leaves a smoother finish than 24 or 36 grit discs.

These discs are typically packaged in quantities of 25 per pack.

This disc features a standard 7/8-inch center hole (arbor) designed to fit most 7-inch angle grinders.
