- When the hole diameter to be chamfered is small or the cutting edges near the front end of the tool are used, use the higher side of the RPM range shown in the table.
In contrast, when the hole diameter to be chamfered is large or the cutting edges far from the tool’s front end are used, use the lower side of the RPM range shown in the table. - When chamfering a small diameter hole (smaller than ø0.394″ (ø10 mm)) in a plunge milling mode, peck-feeding should not be used.
- When the hole diameter to be chamfered is smaller than ø0.394″ (ø10 mm) or the cutting edges near the tool’s front end are used, the feed should be set within 0.006 ipt (0.15 mm/t).
