Round or Square Stock Drilling Jig

thingiverse

I made a jig for drilling round or square stock with a precise center hole, ensuring the drill stays centered on the material. A simple V-shaped design allows for accurate drilling every time. Two versions exist: one features a 0.5-inch hole and the other has a 0.1875-inch hole, catering to different drilling needs. If the initial hole is too small, it can be easily expanded for larger drills.
