Notes: When chamfering a small diameter hole (smaller than ø10 mm) in a

When the hole diameter to be chamfered is small or the cutting edges near plungemilling mode, peck-feeding should not be used. the front end of tool are used, use at higher side of the revolution range When the hole diameter to be chamfered is smaller than ø10 mm or the shown in the Table. cutting edges near the tool's front end are used, the feed should be set In contrast, when the hole diameter to be chamfered is large or the cutting within 0.15 mm/t. edges far from the tool's front end are used, use the lower side of the revolution range shown in the Table.
