Walter 1.5x1 Inch Mounted Flap Wheel 40 Grit

Smooth Out Tight Spots with Walter's 40 Grit Flap Wheel

For welders, the finishing stage is just as important as laying the bead, especially when working on visible joints or preparing for coating. The Walter 15F104 Mounted Flap Wheel is your go-to solution for cleaning up welds in tight corners, inside pipes, or on irregular surfaces where a standard 4-1/2" angle grinder just won't fit. With a 1-1/2" diameter and a 1" width, this wheel mounts easily into your die grinder, giving you the precision control needed to blend welds seamlessly without gouging the base metal.

This specific wheel features a coarse 40 grit abrasive, which is aggressive enough to knock down heavy spatter, remove scale, and blend out rough grind marks quickly. Despite its aggressive cut, the flap design provides a softer touch than a solid grinding stone, allowing for a smoother transition between the weld and the parent material. This is particularly useful when working with stainless steel, where leaving deep scratches can lead to corrosion issues later. The flaps conform to the shape of your workpiece, making it incredibly easy to round off edges or clean up inside radii.

Walter is known for making abrasives that last, and this flap wheel is no exception. The cloth backing is tough and resists shredding, even when you are working on sharp edges. Because the flaps wear away to reveal new grain, you don't have to push hard to get the wheel to bite—let the RPM of your tool do the work. Whether you are polishing up an aluminum intake, prepping a steel bracket, or finishing a stainless handrail, this 40 grit wheel helps you get the job done faster with a professional-grade finish.

Why Welders Choose This Wheel:

• Access: Gets into tight corners and IDs where other tools fail.
• Control: Blends welds smoothly without undercutting.
• Durability: Lasts longer than cheap generic wheels, saving you downtime.
