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-PLUS™BT30) integrated arbor
types are available.
Work Material
・Aluminum and 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 more teeth (3 edges per inch).

Do not exceed the maximum allowable spindle speed (n max) specified for each cutter diameter. (*See the table on the upper right.)
● Reduces running costs by significantly increased number of regrinding (to 1.8mm).
Assuming the amount of regrinding

to be 0.2mm, an edge can be used
up to 10 times.
