Flap Wheel Engineering

The 3M™ Flap Wheel 341D is a unique engineering marvel that features hundreds of tightly packed, overlapping abrasive cloth flaps arranged radially around a hub. Each flap is flexible and covered with sharp-cutting aluminum oxide mineral bonded with resin. When mounted to a die grinder or flexible shaft tool, the flaps rotate centrifugally, making continuous contact with the workpiece. As the flap wears away, new abrasive grain is exposed, and the wheel continues to cut.

The flexible nature of the flaps makes it highly conformable to surface contours and irregularities. Flap wheels are far less likely to gouge or mar the work surface. The forgiving quality of this abrasive wheel allows even inexperienced operators to obtain professional results.

The 3M™ Flap Wheel 341D is available in 1-, 2-, and 3-inch diameters. A T84 threaded mandrel is attached to the center of each wheel. The T84 mandrel has a 1/4-20 inch thread that screws into our 81A wheel adapter kit to attach the flap wheel to your power tool. Quickly spin the wheels on and off. No special tools are needed. Maximum RPMs are 20,000 for the 3-inch wheel, 25,000 for the 2-inch wheel, and 30,000 for the 1-inch wheel.

Recommended Applications

The 341D flap wheel is typically used on a die grinder to set a linear finish or set a scratch on stainless steel and other substrates. It is also used to deburr tube or pipe internal and outer diameters and for small or hard-to-reach areas where larger flap wheels are too big or cumbersome.
