Our Square Gauge Blocks are a quick way to make many easy, accurate set-ups. A great way to make exact depth movements on plunge routers. On table routers, they're perfect for setting distances from the fence to the cutter, or for checking the bit height above the table. Supplied in 1/8, 3/16, 1/4, 3/8, and 1/2 squares. Blocks can be stacked to cover a wider range of sizes. A very helpful tool!

Whiteside Machine is regularly rated as #1 for cut quality and #1 for value by Fine Woodworking magazine.

Whiteside Machine was originally a machine shop, many decades ago. They were machining precision router bodies for a customer. The customer went broke leaving them sitting on the router bodies so they decide to finish them and sell them. This is a real story of courage, resourcefulness, guts and just plain stubbornness.

Decades later they are still stubborn about absolutely top quality and beautiful tools.
