BHA Aluminum Oxide Shank Mounted Flap Wheels, 1-1/2” x 1” x 1/4”, 120 Grit - 5 Pack

These take alot of material off quickly and they last very very long. I am ver surprised at how good these works.

Needed to open up a muffler pipe a mm or two for a motorcycle. These worked as I expected. got them fast. I didn't need 5 for the job but no one sells just 1. Price wasn't unreasonable at a little over $2 each.

They don't really compare to the more expensive abrasive wheels as far as durability but for the money they work great in a pinch.

Quality product.

Polished up the inside of a pulley perfectly

The BHA flapper wheel did the job. It honed out the old pinion bearing to be used as a set up bearing for setting pinion depth. It can be slid on and off pinion shaft by hand when using a crush sleeve eliminator to set pinion depth.

Used one of these to grain the stainless steel lockdown bar on an old pinball machine. Using a cordless drill you would have to tighten it back up into the drill fairly often but not this products fault. Great price fast shipping.

The wheels are built as described. Well made. My issue is that the individual sanding flaps are very stiff. This means you have to press the spinning wheel really hard against the wood being sanded. Otherwise, the flaps won't bend far enough to expose the gritty side of each sandpaper flap that do the sanding. And some projects are too fragile to stand up to the force needed to do the job. The flaps need to be longer and/or less of them. I cannot speak to how these works on metal.

I had a very specific use for these. I was honing out a 1.5" abs plastic pipe to make it a slip-fit over steel tubing. A pretty low-stress application for an abrasive, but they did the job.
