The “Coolant Thru” line of coolant-through toolholders features delivery through the shank, providing optimal insert lubrication and cooling, longer cutting tool life and improved Swiss-type machining, the company says. Holders feature interchangeable coolant orifice plates at the insert top level, which are designed to enable exact control over coolant volume, pressure and velocity as low-, medium- and high-flow action for more efficient chip removal.

 
The holders are available with high pressure to 10,000 psi; stock sizes are 1/2” and 5/8” square shank; and other sizes are available upon request. The insert pocket conforms to ISO-style turning inserts—80 degrees, 55 degrees and 35 degrees. The coolant inlet of the toolholders uses standard NPT fittings, eliminates use of solid coolant delivery lines, allowing for faster setup and more accurate coolant delivery position to the insert. In addition, there is no need for a custom gang plate, and no coolant manifold installation is required or other modifications to the coolant feed systems.
 
According to the company, the toolholders improve chip control and removal, extend tool life and make running tough jobs easier. Stops to clear chips are eliminated as well.
