08B462 - Walter HP Combo 4.5-inch Cut and Grind Wheel Type 27

Cut, Grind, and Keep Moving

Every welder knows the frustration: you make a cut, and then you have to stop, find your wrench, swap out your zip wheel for a grinding rock, and then deburr the edge. It kills your momentum. The Walter HP Combo Grinding Wheel (08B462) changes the game by letting you do it all with one wheel. This isn't just a thick cutting disc; it's a specially reinforced Type 27 hybrid built to handle the abuse of side-loading while still slicing through metal cleanly. With a 1/8-inch profile, it’s thin enough to cut fast but tough enough to grind, notch, and groove without falling apart.

Built for the 4-1/2" angle grinder, this wheel is a workhorse for fit-up and repair jobs. You can trim a piece of angle iron to length and immediately bevel the edge for a weld, all without changing your setup. The depressed center design allows the locking nut to sit flush, giving you better clearance for getting into tight corners or grinding flat surfaces. It bites into steel and stainless steel aggressively, thanks to the A30 grit, and it holds up longer than the cheap stuff, so you aren't constantly throwing worn-out nubs in the trash.

Safety is huge when you're leaning into a grinder, and the HP Combo gives you peace of mind. Because it's reinforced for off-hand grinding, you don't have to worry about the wheel shattering if you apply some side pressure. It’s designed for the real-world way welders work. Whether you are gouging out a crack for repair, cleaning up a root pass, or just cutting stock, this wheel handles it smoothly. It even works on aluminum, making it a versatile addition to your gang box.

Sold in packs of 25, these wheels are ready for the long haul. Walter is known for making abrasives that last, and the HP Combo is no exception. It cuts free, doesn't bog down your machine, and saves you the hassle of carrying two different types of wheels for every job.
