HSK – DIN 69893 Shrink Fit Holder

Shrink fit holders are known as thermal expansion tool holders. Upon heating the tool holder expands, and the tool is slipped in and subjected to rapid cooling. On cooling, they clamp the tool very tightly in such a way that the tool becomes integrated with the holder thereby offering high levels of accuracy and rigidity. They offer a very slim profile and can be used to machine difficult to reach features.

They permit increased feeds and speeds while eliminating tool slippage. They also offer increased tool life, lower tooling cost and greater accuracy and repeatability. They have become the popular tool holder of choice for the die and mould industry. JPAC Precizions offers these shrink fit holders with face coolant holes to enable coolant supply direct to the cutting tool.
