Should I use shrink fit?
If you do high speed, or high torque machining you should seriously consider the benefits of shrink fit technology. Your investment will pay for itself many times over.

Performance
With shrink fit toolholders vibration is reduced and cutting is noticeably faster and smoother. Manufacturing times can be reduced while maintaining the quality and accuracy demanded by today's competitive markets.

How it works
Shrink fit uses the expansion and contraction properties of metal to provide extremely powerful tool holding. The bore is slightly smaller than the tool shank, and when heated it expands just enough to allow the tool to be inserted. When it cools, the contraction holds the tool with 10,000 lbs of force.

Feature	Benefits
10,000 lbs clamping force minimum	T.I.R. from 0.0" to 0.0002" max.
	Permits increased feeds & speeds
	All but eliminates the chance of slippage

Shrink-fit tool changing	Change tool in only 6 seconds
	Pre-set tools off-line
	Never buy collets and nuts again
	No need to use torque wrenches or vises
	Works with carbide and HSS tools

Highest rigidity	Permits increased chip load
	Improved accuracy / repeatability
	Reduced carbide tool wear / reduce tooling costs
	Increase spindle bearing life

One-piece construction	Best possible balance
	Thin profile for machining hard to reach areas
	Allows short gage lengths for increased rigidity
