Can anyone recommend a spiral bit for pocketing and profiling hardwood at depths of up to 60mm? I’ve been using a straight bit which is ok but not that happy with the results which need a bit of sanding. I think a spiral bit would do a better job at reducing chatter but struggling to find an (affordable) bit at this length which will fit my er20 collet. Also when profiling at this depth the channels get clogged up with chips even with the vacuum on!
