Tungaloy Enhances T9200 Steel Turning Inserts with New Grades and Geometries

Published Date

Tungaloy has expanded its T9200 CVD grade insert series to include T9205 and T9235 grades as well as the -TSF and -TM style chipbreakers. Both T9205 and T9235 provide outstanding wear resistance in the P05 and P35 application ranges surpassing existing CVD grades. These capabilities are possible due to Tungaloy’s innovative coating technologies, including:

  • Extremely wear resistant Al2O3coating in a thick and uniformly aligned layer
  • Ultra-hard ceramics for the outermost layer
  • PremiumTec – Tungaloy’s exclusive post surface treatment technology

T9205 and T9235 provide long and stable tool life which maximizes productivity. Combined with the -TSF and -TM style chipbreakers, this latest line meets needs in a wider spectrum of steel turning applications. This expansion complements the preceding T9215 and T9225 grades of the T9200 series.

  • ceramics


    Cutting tool materials based on aluminum oxide and silicon nitride. Ceramic tools can withstand higher cutting speeds than cemented carbide tools when machining hardened steels, cast irons and high-temperature alloys.

  • chemical vapor deposition ( CVD)

    chemical vapor deposition ( CVD)

    High-temperature (1,000° C or higher), atmosphere-controlled process in which a chemical reaction is induced for the purpose of depositing a coating 2µm to 12µm thick on a tool’s surface. See coated tools; PVD, physical vapor deposition.

  • 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.

  • wear resistance

    wear resistance

    Ability of the tool to withstand stresses that cause it to wear during cutting; an attribute linked to alloy composition, base material, thermal conditions, type of tooling and operation and other variables.
