OVERVIEW

Chew Through Metal with the Walter HP XX

When you have a mountain of welds to grind down or heavy scale to remove, you don't want a wheel that glazes over or wears down in five minutes. You need a beast. The Walter HP XX Grinding Wheel (08H502) is that beast. Designed for the professional welder who demands performance, this 5-inch Type 27 wheel is built to handle the toughest grinding jobs in the shop. It features Walter's latest high-performance bonding technology, which means it stays sharp and aggressive right down to the nub.

The "XX" stands for extreme performance. This wheel is formulated to provide the longest life of any grinding wheel Walter makes. For you, that means you aren't stopping every ten minutes to spin on a new rock. You can keep your hood down and your grinder spinning. The 1/8-inch thickness gives you the durability needed for heavy edge grinding, shaping, and deburring without the fear of the wheel chipping or shattering under pressure. It is specifically tuned for both steel and stainless steel, so you don't have to worry about contaminating your stainless work with a carbon-only wheel.

Ergonomics matter when you are grinding all day. A wheel that cuts faster requires less pressure from you, saving your arms and back from fatigue. The coarse 24-grit composition of the HP XX rips through material, allowing the tool to do the work. Whether you are beveling pipe for a root pass or smoothing out a cap, this wheel gives you the control and power you need to produce a professional finish in record time. Upgrade your angle grinder with the HP XX and feel the difference premium abrasives make.
