CAT 50 shrink fit tool holders

Shrink fit 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.


Shrink Fit Features

• T.I.R. only 0.0001"

• Balanced to 24,000 RPM at G2.5

• Extremely rigid tool holder

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

RUN BETTER: Shrink Fit 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.
