X-treme Jet External Thread Turning Toolholder

Designed for more effective coolant flow and improved chip control, Carmex’s new X-treme Jet External thread turning toolholder provides two connecting options via an elbow fitting and top clamp to more precisely direct the coolant flow to the cutting edge, where it is most effective.

Available in both RH and LH configurations, the X-treme Jet is coated for maximum abrasive resistance. Ideal for high-pressure coolant applications, the directed flow reduces cutting edge temperature, resulting in higher performance, improved chip flow and longer tool life.

Jim White, national sales manager for Carmex USA, comments: “Putting a newer high-quality insert in a traditional toolholder is like installing a custom-built engine in an older car. To achieve maximum insert performance, it’s necessary to select the right combination of tool and toolholder. The new X-treme Jet is designed to optimize cutting performance, while providing the additional efficiencies of improved coolant effectiveness and longer tool life.”

Related Glossary Terms

  • abrasive


    Substance used for grinding, honing, lapping, superfinishing and polishing. Examples include garnet, emery, corundum, silicon carbide, cubic boron nitride and diamond in various grit sizes.

  • 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.

  • toolholder


    Secures a cutting tool during a machining operation. Basic types include block, cartridge, chuck, collet, fixed, modular, quick-change and rotating.

  • 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.
