Small Diameter Cutter for Aluminum Alloy

SRF

■ 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.
