TNMG 220404 GT720 Tungaloy turning insert — cermet grade for finishing and light turning

The TNMG220404 GT720 Tungaloy insert is an ISO-standard triangular turning insert engineered for finishing to light turning of steel, prioritising surface quality and dimensional consistency

• ISO TNMG 220404 triangular insert
• GT720 cermet for fine finishing
• Double-sided chipbreaker, with hole
• 60° cutting angle, 0° clearance, 0.4 mm radius

Delivering consistent surface finish and dimensional control

The GT720 cutting grade combines the benefits of a cermet composition with a geometry tuned for fine finishing, so machining delivers improved surface finish and tighter tolerances with reduced burr formation. A controlled, steady wear pattern contributes to predictable component quality over the life of the edge, reducing rework. For practical use, the modest corner radius and the finishing-oriented grade mean fewer passes are needed to meet dimensional specifications, which supports higher first-pass yield in series production.

Predictable chip control and reliable process stability

The triangular insert with a double-sided chipbreaker and a cylindrical hole supports repeatable clamping and reliable chip formation under stable conditions. The TNMG220404 form, combined with a 0° clearance angle and a 60° cutting geometry, encourages consistent cutting forces and helps maintain tool orientation in external or internal turning. Where process stability is limited, selecting the appropriate chipbreaker and matching holder tolerance class reduces vibration and improves tool life, delivering more predictable cycle times in day-to-day workshop operations.

Practical compatibility and efficient use in turning setups

Designed as part of the ISO series, this insert offers straightforward interfacing with standard external holders and boring bars; compatibility depends on form, free angle, tolerance class, fixing method, size and thickness. The 0.4 mm corner radius supports fine finishing on steel components, while the double-sided format enhances cost-efficiency through simple indexing. For light to finishing cuts, the cermet grade is especially effective on steel workpieces where consistent edge condition and excellent surface integrity are required.
