Draw line X then draw perpendicular line Y, and where they cross is exactly where to drill... maybe. The fact is it's a bit off half the time.
No more! Incra's innovative 6" x 3" marker rule accurately measures both the X and Y axis at once!
Marking holes are located every 1/16" in every direction, giving you 4,608 different, but precisely located, positions. Also has refernce lines every 1/4", and double reference lines every full inch.
Fences position the rule securely, precision-machined marking holes guide your 0.5mm pencil (included) or scribe to the correct mark. Virtually mistake-proof. USA
