SD - Shrink Fit Holders

Proper cooling is the key to preventing over heating of the tool holders and long life of the H13 tool steel.  EZ Cool units use your shop coolant to returns the holder to a save to handle temperature in 30 seconds.  EZ Shrink Machine is a 3kw, 30 second unit that functions with 1/8-3/4 (3mm-20mm) cutter shanks (carbide only).  
Pre-programmed and user adjustable EZ Shrink is simple and effective.

Jet-Blast Options to fit YOUR Application
We at Pioneer have invested in an EDM Drilling machine which allow us to customize Jet-Blast  coolant  holes to your application.

It comes down to coolant volume.

Every Jet-Blast Holder or collet comes with 2 ports standard. Depending on style and type we have the ability of adding as many holes as your coolant volume can support without losing pressure.  
The goal is to create a reducing effect to the volume of coolant to maintain or increase pressure.  This allows for increased chip evacuation and free cutting.

Any standard Shrink can be modified from stock.  Adding a “J” to the end of the part number will provide you with 2 coolant ports.  
Need additional ports? Add “J 4-Port” to the part number for additional ports (additional fees will apply).
