Jet Blast Option

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).

The 1/2 Moon Project

Years ago we outsourced our EDM work and all Jet-Blast was 1/2 moon. That source went out of business and we purchased machines and followed the machine manufacturer's recommendations. Many customers preferred the 1/2 moon

We have changed processes and now can offer 1/2 moon standard on most holders.
