Good addition to my jig collection!!!
Size: 9 Holes
It works great! Would be better if it had a Brad style drill bit instead of the ones that came with it.

Drill bits not sharp
Size: 9 Holes
Just used the shelf pin hole jig for the first time. Seams to be a decent product. The failure with this product is the all too Repetitive China Factor. As everything they make to be sold in America has that inherent built-in factor for failure. It starts with the drill bit. Not sharp at all wich causes you to add more pressure than is needed, which causes the depth collar to slide on the drill bit, because it is made of cheap metal. Be very careful. After about 8-10 holes check your depth.
