BT shrink-fit tool holders

ShrinkFIT Features

  • Maximum T.I.R. only 0.0001"
  • Balanced to 25,000 RPM at G2.5
  • Comes with coolant-thru set screw installed.

ShrinkFIT tooling improves cutting tool life, cutting ability, surface finish, and produces less wear-and tear on spindle bearings. Ideal for high speed or high torque machining applications.

RUN FASTER: Spindle speeds and feeds are increased to reduce cycle times & increase R.O.I.

RUN BETTER: ShrinkFIT permits better balanced chip loads so machining is more accurate and finish is improved.

SAVE MONEY: Tool life is extended by as much as 700% dramatically impacting your tooling budget.
