For quite a while I have been using the Kreg set up bars for various set up tasks in my shop. Before I bought these I had made a set of different thicknesses of hardwood blocks. That worked well, but the Kreg blocks offer more versatility. They come in sizes from 1/8” to 1/2” in 1/16” increments, nicely organized in a handy case. ( If you follow my work, you know I love organization!)
I frequently use mine for setting the depth on my drill press. Just bring the bit down just touching the work piece, lock the quill, and adjust the stop the thickness of the set up block.
Set the height of saw blades or router bit as well. Or use the other side to check dado and groove depths.
Thanks for looking!
