Walter Combo Zip 4.5-Inch Cut and Grind Wheel

Cut, Notch, and Deburr in One Go

As a welder or fabricator, you know the hassle: you make a cut with a thin zip wheel, but then you have a sharp burr or a jagged edge that needs cleaning. You have to stop, spin off the cutting wheel, mount a grinding rock or flap disc, clean the edge, and then switch back to cut the next piece. The Walter Combo Zip (11T842) eliminates this entire dance. It is the "Swiss Army Knife" of abrasive wheels, giving you the freedom to cut through 4-1/2" pipe, angle iron, or plate, and then immediately use the side of the wheel to deburr the edge—safely and effectively.

Standard cutting wheels are dangerous if used for grinding; they are designed only for radial pressure. The Combo Zip is different. With a thickness of 5/64" (approx. 2mm), it is slightly thicker than a standard Zipcut but significantly thinner than a grinding disc. This unique geometry, combined with heavy-duty reinforcement, allows it to withstand the lateral forces of notching and light grinding. You can bevel a pipe end for fit-up or smooth out a tack weld right after cutting, all without putting your grinder down.

The 11T842 is equipped with a metal hub for extra rigidity, ensuring the wheel doesn't flex dangerously during use. It runs smooth and cool, preventing the heat discoloration on stainless steel that often happens with thicker grinding rocks. This wheel is rated for a maximum of 13,300 RPM, making it compatible with all standard 4-1/2" angle grinders. By consolidating two steps into one, you not only save time but also reduce the weight of the gear you have to carry to the job site. For mobile welders and fitters, the Combo Zip is an essential addition to your tool bag.

Stop wasting time on wheel changeovers. Get the wheel that works as hard as you do. The Walter Combo Zip delivers the legendary speed of a Zip wheel with the versatility of a grinder, keeping you safe and productive all day long.
