Tungaloy Corp. announces the expansion for EasyMultiCut, the multi-functional tool series for grooving: the ETFR-CHP toolholder for face grooving with a coolant hole for high-pressure internal coolant supply. EasyMultiCut features a unique self-clamping insert that provides high tool rigidity.

The toolholder has no top clamping parts to hold down the insert, so smooth chip evacuation is possible in deeper grooving applications. Thus, EasyMultiCut delivers outstanding productivity even in face grooving operations where chip evacuation is usually difficult.

Also, the toolholder has a coolant hole, therefore ample coolant is constantly supplied to the cutting edge, achieving stable and long tool life.

Main features:

■ Applicable for face grooving with groove width 0.157” (4 mm); ø1.181” to 19.685” (ø30 to 500 mm)

■ Maximum groove depth: 0.984” (25 mm)

■ Excellent chip evacuation allows high speed machining, leading to incredible productivity.

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.

  • grooving


    Machining grooves and shallow channels. Example: grooving ball-bearing raceways. Typically performed by tools that are capable of light cuts at high feed rates. Imparts high-quality finish.

  • toolholder


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