How to read template

Cutter overhead is a little bit tricky. There are number of perfect overheads for the router bit. In case of the router bit V14 D12.7 there are following: 2.81, 6.82, 10.83, 14.84 mm

PyRouterJig pick up the perfect fit closed to the bit depth value. You can expect weak join in case the bit depth is less than overhead and tight if it is greater.

In case join tolerance is tiny small (the gap is less than 0.01mm or 1/32") the template display only a single value.
