1 igh Efficiency for F Type Expansion General Features The F type high efficiency cutter for aluminum alloy achieves machining without burrs using a unique insert shape. ew FF types with oil holes and BBT30 (BIG-LUS BT30) integrated arbor types are available. aterial and aluminum alloys Other non-ferrous metal ot suitable for cast iron or steel.

(*See the table on the upper right.) Binderless SUICRYSTAL 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. * Given the condition of normal wear with ap of 1.4mm or less Regrinding ortion 1.8mm ax. Regrinding Amount The regrinding amount has been significantly increased compared to conventional screw-lock types. Improved chip evacuation with internal coolant (FF type and FF-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.) BIG-LUS is a trademark of BIG DAWA SEIKI CO., LTD. Can also be used with BT30 spindle machines. 30
