These magnetic shims can be stacked or ''split'' to create a handy setup block from 1/16'' to 1-1/8'' thick, in 1/16'' increments. Use them to set dado depths, router bit and drill bit heights, and distances from your router table fence to the bit. No more stooping down and squinting at a wobbly tape measure while you rotate a sharp blade with your fingers. Mag Shims sit firmly on the surface, and can be used as a solid block, or fanned open to create a staggered block when setting blade and bit heights.


  • Sticks to any ferrous surface for safe, convenient storage and easy access
  • High visibility—won't be accidentally swept up and tossed out
  • Also can be used as 1/8'' shims when spacing Euro style doors and drawers, and for common assembly operations
  • Use the corners of any Mag Shim to draw the following outside radiuses: 1/8", 1/4", 1/2" and 3/4", or a 1/4" inside radius
