Coolant Thru Toolholders

August 01, 2011

GenSwiss announces the launch of "Coolant Thru" line of coolant through tool holders featuring delivery through the shank providing optimal insert lubrication and cooling, longer cutting tool life and improved Swiss type machining. Holders feature interchangeable coolant orifice plates at the insert top level 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 ½" and 58" square shank, other sizes available on request. Insert pocket conforms to ISO style turning inserts, 80, 55 and 35 degrees.

The coolant inlet of the tool holders 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 custom proprietary gang plate and no coolant manifold installation is required, or other modifications to the coolant feed systems.

"The new 'Coolant Thru' holders improve chip control and removal, extends tool life and makes running tough jobs easier. Stops to clear chips is eliminated, resulting in less insert changes and delivering proper cooling. We think it offers users another option for greater Swiss machining efficiency," comments Scott Laprade, GenSwiss Marketing Manager.

Related Glossary Terms

  • coolant


    Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.

  • feed


    Rate of change of position of the tool as a whole, relative to the workpiece while cutting.

  • shank


    Main body of a tool; the portion of a drill or similar end-held tool that fits into a collet, chuck or similar mounting device.

  • turning


    Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.
