    Jet Blast Options

    Modify any of our End Mill, Shell Mill or Shrink Fit holders with Jet-Blast!

    Not only do we carry more standard projections than anyone else in the industry but now you can order any of our holders with Jet-Blast. We have invested in the equipment to install coolant ports in any of our stock catalog holders.

    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.

    Jet-Blast

    Full diameter coolant ports are available on demand. Please specify when ordering.

    • Any End Mill, Shrink or Shell Mill Holder with a 10" projection or shorter
    • Altered in Chicago for quick turn around, many same day!
    • Expedited Service Available
    Multi-Port Jet Option
    Define your coolant flow with increased volume

    Adding additional ports will give the holder a shower head effect, for customers with high volume systems.

    Multi-Jet
    Fit the holder to your machine's coolant system!
    • Need to increase pressure?
    • Need greater volume of coolant?

    Retention knobs all have different coolant holes. Some as large as 0.44" and as small as 0.07". Jet-Blast can be fit to your machine's coolant system to achieve the best possible coolant flow and pressure.
