Milling aluminum

Cutter weight and insert comparison

HFC cutter weight is half that of others on the market
A 125mm 4.921” cutter + BT30 arbor* weighs 2kg 4.4 lbs or less.
At that weight, the 125mm 4.921” cutter can even be used on a compact machine!
* Using a BT30-FMNA25.4-40 ( 0.7kg 1.54 lbs )

Safety clamp mechanism

Unique pocket design uses a wedge shape and centrifugal forces to help prevent the insert from sliding out.

Insert can be reground up to 4 times
  • Each regrind will reduce the width and height of the insert by 0.1mm .004” from its previous dimension.
  • A star is added to indicate the number of regrinds.
  • Maximum number of regrinds is 4 times (the total dimensional change will be 0.4mm .016” from the new product)

*The number of re-grinds per insert may vary depending upon cutting edge damage evaluation.
