5 Piece Set Solid Brass Set Up Bar Gauge Blocks, 2-1/2" Long

This Brass Set-Up Gauges usually made from brass so they won't damage cutting edges. Sizes are 1/8", 3/16", 1/4", 3/8" and 1/2" square. The nice thing about set-up blocks is that there's no measuring involved, they're perfect for setting distances from the fence to the cutter, or for checking the bit height above the table
