Three Pin Wrenches

Maybe you’ve lost the original pin wrench that came with your grinder, or maybe you’re sick of keeping up with a different wrench for each grinder you own. If so, you’re in luck — you can choose from several replacement options.

Harbor Freight sells a cheap adjustable pin wrench that may fit the bill. It adjusts to fit grinder hubs from 3/8″ to 1-1/16″. For only $4 this cheap-ass tool of the bunch could be yours.

If Harbor Freight tools make you cringe, try an almost identical model from Garrett Wade for four times the price. Don’t fear, you’re getting something for the extra dough — this wrench can accommodate a wider variety of grinders, with hubs from 3/8″ to 1-9/16″.

Amazon also sells an adjustable pin wrench that looks like a pair of dividers. For $15 this 7″ long wrench fits a much larger range of grinder hub sizes. Made of chrome vanadium steel, this wrench features 5/32″ diameter pins. Customers have complained that these pins are too large for their grinder — but that’s nothing a few minutes on the grinding wheel can’t solve.

    I likes the snapon. The last time I needed one of these (for some wheel bearings) I welded one up with some round stock and a strip of steel with a bolt welded on the back. It was bent and useless by the time I finished, so a store-bought would be nice.
