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 new 6" x 3" marker rule accurately measures both the X and Y axis at once!
Fences position the rule securely, precision-machined marking holes guide your .5mm pencil (included) or scribe to the correct mark. Virtually mistake-proof. USA
