Seco Tools' JETI Toolholders Feature Interference-Free Internal Coolant Capabilities

Additions to Seco Tools’ JETI (Jetstream Integrated) toolholders are said to eliminate the components and connectors commonly required for coolant-through tooling that hinder grooving, parting-off and other turning operations. With interference-free internal coolant capabilities and the option to switch the underside stream channel on and off, these expansions to the range of MDT (multi-directional turning), X4 (grooving and parting-off) and 150.10 (parting-off) toolholders add operational stability and reliability while improving surface finishes.

To optimize machining, chip control and process reliability, JETI tooling aims high-pressure coolant directly to the cutting zone through internal channels in the tool holder. JETI Duo incorporates upper and lower cooling channels with the ability to activate or deactivate the underside stream. Side and back coolant connections enable these holders to function on machines with conventional coolant delivery systems.

JETI enables application flexibility of coolant delivery without external hoses, fittings and spare parts that can diminish productivity and raise costs, the company says. Square-shanked MDT, X4 and 150.10 holders are available in sizes of 20 × 20 mm and 25 × 25 mm sizes. MDT holders accept inserts from 2 to 8 mm, and 105.10 toolholders accept size-15 blades.
