A job for an annular cutter, hole saw or boring bar (or some combo thereof). But I want to play with a DRO feature: cutting an arc (or, CNC the very slow way).
The job: miter a block for welding to a tube:
Nothing special about this job just a bit different approach.
Slow and tedious but I can take bigger bites with an endmill than a boring bar and I don’t have annular cutters and dislike using hole saws.
