Got a sort of a ps: I broke the last .125" tool I had yesterday on this code with it touched off at about .5mm clearance: g61 [...] (end of hole maker code, tool is 15mm into work) G0z0 G0x0y0 from the mark it left on the edge of the hole, the g0x0y0 move started about 1mm down. With G61 in effect, that should not have been allowed. Part damage was minimal as it was machined away by a subsequent counterbore operation.
