GenSwiss’s Multidec 3000 coolant-through toolholders incorporate an internal coolant jet stream aimed perfectly at the 3000 series insert edge, providing optimal lubrication and cooling, longer insert life for the range of front turning, back turning, grooving and threading operations, the company says. The holders are designed for pressures more than 2,000 psi and are offered in stock sizes 1/2” and 5/8” square shank, with other sizes available on request. Two coolant inlet ports are designed to suit specific machine tool configurations. In addition, the holders eliminate use of solid coolant delivery lines, allowing for faster setup and more accurate coolant delivery position to the insert. 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 GenSwiss.
