Shallow grooving inserts

Share This Post

The Tungaloy Corp.’s new series of shallow grooving inserts are designed with three cutting edges for accurate and cost effective grooving of turned parts in the small turned parts sector.

The new GTGN insert series are used with Tungaloy’s SH730 grade to deliver exceptional performance and tool life on steel, stainless steel and heat resistant alloys, according to the company. The PVD coated SH730 incorporates a (Ti,Al)N coating that provides excellent chipping and welding resistance. Additionally, the micro grain substrate improves the plastic deformation to generate remarkable toughness, which improves tool life a consistency of the cutting edge without sudden fracture. This is a necessity for such sharp inserts that deliver impeccable accuracy and quality levels.

The inserts are available with groove widths of 1, 1.2, 1.4, 1.7, 1.95 and 2.25 mm with a maximum grooving depth from 1.25 to 1.8 mm. Provided in left or right hand format, the inserts are suitable for external and internal toolholders.

Tungaloy has made the new series compatible with a variety of existing toolholders to reduce inventory and toolholder costs. The simple changeover of the insert shim allows users to utilise Tungaloy’s TungThread series in the same toolholder to reduce tooling inventory and costs.

The CE toolholder that is compatible with both the GTGN and the TungThread is available with an overall length from 100 to 150 mm with the shank size of 12, 16, 20 and 25 mm. The steel shank toolholder is available with the option of either a clamp-on type or alternately a dual clamp holder, with a dual clamp type being available in both left and right hand variations. The B-CE external toolholder for gang tooling type lathes with a clamp-on assembly is provided with a toolholder height of 32 mm and an overall length of 150 mm.

The internal toolholders are also available in right and left hand designations with a dual clamp type assembly. This CN toolholder is available as a steel shank or a carbide reinforced shank that is capable of machining a minimum bore size of 24 to 37 mm diameter. This depends on the tool shank diameter that ranges from 20 to 32 mm for robust machining of larger turned parts. With an overall length from 170 to 250 mm, the CN type toolholders are suitable for a vast range of turned part dimensions.
