High Efficiency Cutter for Aluminum Alloy sio n HF Type E x p a n ■ General Features The HF type high efficiency cutter for aluminum alloy achieves machining without burrs using a unique insert shape. New HFFH types with oil holes and BBT30 (BIG-PLUSTM) integrated arbor types are available. Work Material ・Aluminum alloys ・Other non-ferrous metal （ Not suitable for cast iron or steel. ） ■ Characteristics ● Achieves high-efficiency milling with vf of over 20,000mm/min thanks to its multi-edge design (3 edges per inch). High Feed, High-efficiency Milling with Multi-edge Design Conventional Tool 2,880mm/min fz=0.08mm/t 3.4 Times Machining Efficiency HFF12080R fz=0.16mm/t 9,800mm/min 0 2,500 5,000 7,500 10,000 vf (mm/min) ●Maximum Allowable Spindle Speed and Feed Rate Cutter Diameter n max vc fz Max.

(*See the table on the upper right.) Profiling Groove/ T-Slot ● Reduces running costs by significantly increasing the insert regrinding amount (to 1.8mm). Assuming the amount of regrinding Chamfering Max. Regrinding Amount to be 0.2mm, an edge can be used Aluminum/ Light Alloys up to 10 times. 1.8mm High-Speed （* Given the condition of normal wear with ap of 1.4mm or less） Cast Iron Regrinding Portion The regrinding amount has been significantly increased compared to conventional screw-lock types. ● Improved chip evacuation with internal coolant (HFFH type and HFFH-BBT30 type) The effect of internal coolant controls chip blockages and packing in the work material and improves tool life. (Use an arbor that supports internal coolant.) *1 BIG-PLUSTM is a trademark of BIG DAISHOWA SEIKI CO., LTD. *2 Can also be used with BT30 spindle machines. H128
