OVERVIEW

Rip Through Welds Faster with Coolcut XX

When you have a long day of heavy grinding ahead, the last thing you want is a disc that stops cutting after five minutes or requires you to lean your entire body weight into the grinder. The Walter Coolcut XX 5" Sanding Disc (36 Grit) is built to solve exactly that problem. This isn't your average sandpaper; it's a high-performance ceramic tool designed to chew through steel and stainless steel with aggressive speed. If you are leveling heavy MIG welds, taking down TIG reinforcement, or beveling plate for the next pass, this 36-grit disc provides the bite you need to get the job done in record time.

The secret lies in the ceramic grain structure. Unlike traditional grains that round off and generate heat, these grains fracture to stay sharp. This means the disc does the work, not your muscles. You can apply lighter pressure and still achieve massive stock removal, which saves your wrists and arms from fatigue over a long shift. The "XX" stands for extreme performance, and it lives up to the name by lasting significantly longer than standard zirconia discs. This 5-pack (15X503V) is perfect for grabbing a few discs for a specific job or stocking your personal toolbox without carrying a massive box.

Heat is the enemy of a good finish, especially on stainless steel. The Coolcut XX is formulated with special cooling agents that keep the workpiece temperature down. This prevents the metal from warping or turning that dreaded rainbow color, saving you from having to polish it out later. To use this disc, simply mount it on your 5-inch angle grinder using a compatible backing pad (like the Walter Turbo-Action pad for maximum aggression). Whether you are in the fab shop, on a pipeline, or doing maintenance repair, the Coolcut XX 36 Grit disc is your go-to for heavy-duty material removal.

FAQ

You need a 5-inch backing pad with a 7/8-inch arbor or 5/8-11 nut. For maximum performance and cooling, Walter recommends their Turbo-Action or Coolcut backing pads.

While it can cut aluminum, it is optimized for steel and stainless steel. For aluminum, a disc with specific lubricants to prevent loading (clogging) is usually recommended, though the cool cutting action of Coolcut XX helps mitigate some loading.

The 'V' suffix typically denotes a vending-ready pack or a smaller quantity pack (5 discs) compared to the standard bulk box (usually 25 discs). The product itself is identical.

The maximum safe operating speed is 12,200 RPM. Always ensure your grinder does not exceed this rating.

Ceramic grains are harder and self-sharpen more effectively than zirconia. This results in a faster cut rate, longer life, and less operator fatigue because less pressure is required.

Yes, this is a resin fiber disc with a 7/8" center hole. It requires a backing pad and a locking nut to secure it to the angle grinder spindle.

No, 36 grit is a coarse abrasive designed for heavy stock removal. For finishing, you would step up to finer grits (60, 80, 120) or switch to a conditioning disc.
