Hi-Jet Holders introduce coolant capabilities to machine tools without coolant-through spindles. Hi-Jet Holders minimize overheating and distortion of workpieces and allows coolant-through cutting tools to provide faster metal removal rates by flushing chips out of the holes. With reduced heat generation, tool life is greatly extended.

Coolant Runs Through a Separate Sealing Section
Coolant runs through a separate sealing section called the Merit Set. In the Merit Set, the sealing ring that stays stationary when the body rotates does not come in contact with the body. Only the sealing plate, which rotates with the body, has actual contact with the body. As a result, there is no friction from any seals which can cause body wear. The only wear will be to the Merit Set seals, which are easily replaceable parts.
Easy Maintenance of Worn Parts
Easily replaceable Merit Sets consist of Merit Plates, Merit Rings and O-Rings. Coolant contamination and high speed operations are no longer limiting factors to the service life of the coolant feed holders.
