Cutter weight and insert comparison

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

HFC cutter adjustment and handling procedure

Process

1. Loosen the axial adjustment screw
2. Install inserts (lightly hand tighten)
3. Clean the inserts
4. Adjust height of inserts (initial setup)
5. Tighten wedge set screw (firmly tighten)
6. Final insert height adjustment
