Tungaloy Expands Turning Tool Lines With Left-Handed Inserts

Tungaloy has added 37 left-hand inserts to the TCS18 and TCL18 insert lines of the TetraMiniCut grooving and parting tool series.

Featuring parting and grooving inserts with four economical cutting edges, TetraMiniCut offers an insert clamping method that is said to ensure secure retention and high edge repeatability, machining accuracy and tool life predictability.

The series is now introducing TCS18 and TCL18 inserts designed for left-hand cuts, expanding the product lines that, until now, has offered right-hand inserts only. Grooving and parting tools commonly used in most of the operations performed in conventional CNC lathes and Swiss machines are right handed. As highly advanced multitasking machines with multiple spindles and turrets are gaining popularity to maximize productivity, the need for left-hand tools is increasing as well, which enable simultaneous machining on the right and left-hand spindles of such machines.

TetraMiniCut’s TCS18 and TCL18 geometries feature pressed-to-form 3D chipbreakers that increase chip control. TCS18 incorporates four cutting edges with an optimal rake angle that provides the cutting edge with a good balance of strength and sharpness. TCL18 has cutting edges with a large rake angle that generates light cutting action and reduced cutting load for machining stability.

With this expansion, TetraMiniCut left-hand tooling can now be purchased off the shelf at less costs, while enabling more end users to use the full capabilities of TetraMiniCut’s tool stability and accurate edge repeatability and productivity over an expanded range of grooving and parting operations.
