Walter Coolcut 5-Inch Resin Fiber Disc 36 Grit

Aggressive Stock Removal for Steel Fabrication

When you need to grind down a heavy weld or strip a steel surface quickly, the Walter Coolcut™ 5" Sanding Disc (15C503) is the tool for the job. Built for welders who demand reliability without the premium price tag of specialized ceramic discs, this 36-grit aluminum oxide disc bites into steel to remove material fast. It is the workhorse of the shop, perfect for those initial stages of finishing where moving metal is the priority over achieving a mirror finish.

Heat is the enemy of any abrasive, but the Coolcut is designed to run cooler than standard economy discs. This means the disc lasts longer and you spend less time changing out consumables and more time welding and fabricating. The 5-inch size offers a great balance of coverage and control, fitting standard angle grinders with a 7/8" arbor. Because it is a resin fiber disc, it conforms slightly to the metal surface when used with a proper backing pad, giving you better control than a rigid grinding wheel.

This 25-pack ensures you have plenty of stock on hand for big projects. Whether you are building trailers, repairing heavy equipment, or doing general custom fabrication, the Walter Coolcut 36 Grit disc gives you the aggressive cut you need to get the job done right.
