Small Diameter Cutter for Aluminum Alloy SRF Type ■ General Features The small diameter milling cutter SRF type for aluminum alloy is most suited to high-efficiency machining of aluminum alloys on small machines. ■ Characteristics D Best Suited For Small Machines Especially reliable on BT30 class small machines. D From Roughing To Finishing Processes Utilising SUMIDIA DA1000 Insert with a side edge of 5mm. D Economical NF-type Inserts NF-type SUMIDIA DA1000 inserts lower tooling costs. D High Speed Cutting With SUMIDIA Maximum spindle speeds of up to n = 20,000min-1 (Actual spindle speeds must be set within the rotational limits of your machine and arbor. ) D Simple design for insert run-out Simple insert mounting design for easy yet precise tool adjustments.
