08N502 - Walter Pipefitter 5-Inch Grinding Wheel 1/8-Thick A-36

The Pipeliner's Choice for Root Passes

When you are out on the right-of-way or in the fab shop, you need a wheel that understands the job. The Walter Pipefitter™ 5" x 1/8" (08N502) is built specifically for the guys and gals burning rod on pipe. This isn't just another generic grinding rock; it's a specialized tool designed to handle the specific needs of joint preparation and inter-pass cleaning. The 1/8-inch thickness is the sweet spot—thin enough to get into the bevel and clean out the wagon tracks, but thick enough to hold up when you need to face a land or feather a tack.

We know that contamination is a deal-breaker, especially when you are welding stainless. That is why the Pipefitter wheel is guaranteed iron-free. You can switch between carbon and stainless pipe without worrying about introducing rust or impurities into your weld pool. The A-36 grit gives you a bite that feels aggressive but controlled, letting you grind out slag and defects without gouging the pipe wall or losing your bevel angle.

This wheel is tough. It resists glazing and doesn't load up, meaning you spend more time grinding and less time changing out wheels. It runs smooth on a 5-inch grinder, cutting down on the chatter that wears out your wrists by the end of the shift. Whether you are notching for a repair or just polishing up a root pass before the hot pass goes in, the Walter Pipefitter is the wheel you want in your bucket. It’s reliable, consistent, and made for the way you work.
