Tungaloy Enhances Its TungCut Grooving System with New Inserts and Holders


Iwaki, December 2019 — Tungaloy is expanding its TungCut series of grooving tools to include new insert and holder options.

TungCut’s DTE grooving insert offers a versatile design that allows the insert to be used for grooving and turning in both axial and radial directions. The new insert options include DTE3-020 for a cutting width of 3 mm with 0.2 mm corner radii as well as DTE4-080 and DTE5-080 for cutting widths of 4 mm and 5 mm, respectively, both with 0.8 mm corner radii. The inserts are offered in AH7025, a PVD grade dedicated for grooving applications from roughing to finishing.

The popular modular tooling series, TungModularSystem now includes a CAEFR-****-CHP type modular blade enabling OD and face grooving with up to 4.8 mm cutting depths. The blades are offered in two sizes covering cutting widths from 2 mm to 6 mm.

In addition, TungCut expands the monoblock holder lineup in its TungCut toolholder series to include JCTEL and CTER/L lines to meet various cutting depth needs. This expansion further enhances TungCut to be able to provide optimal cutting-edge overhangs in various grooving situations, while minimizing vibration and instability.
