TPGT 070102 SH730 Tungaloy turning insert — Coated carbide, 0.2 mm nose radius

TPGT 070102 SH730 is an ISO-standard triangular turning insert designed for external and internal turning, offering a single-sided chipbreaker and a secure centre hole for positive location

• Triangular ISO insert, size 07
• SH730 grade, coated carbide
• 0.2 mm nose radius
• 11° clearance, 60° included angle

Consistent cutting-edge performance in changing conditions

The SH730 grade is a coated carbide substrate formulated for tough, edge-stable behaviour, which is especially beneficial in smaller tool setups or where engagement conditions vary. This composition helps to extend the interval between indexings and reduces unplanned stoppages, delivering a more predictable production rhythm. The single-sided chipbreaker provides controlled chip formation that supports stable cutting forces and consistent surface finish, translating technical performance into measurable productivity gains.

Secure fit and geometry for precise, repeatable machining

Compatibility depends on insert form, clearance, tolerance class, fastening, size and thickness; the ISO designation ensures interchangeability with matching holders. The cylindrical centre hole with single-side countersink (40°–60°) secures the insert position and assists repeatable seating in the pocket. The 11° clearance prevents rubbing on the flank face, while the 60° included angle influences approach geometry and flexibility of cutting directions. These geometry factors together reduce vibration and support a reliable surface quality.

System-level benefits and practical application guidance

As part of an ISO insert system — comprising the insert, an appropriate external holder or boring bar, a shim/clamp set and replacement screws — the element integrates quickly into existing toolchains. The 0.2 mm nose radius provides a balance between surface finish and edge strength: a small radius refines part finish while maintaining sufficient robustness for intermittent cuts. For turning operations, select a chipbreaker and the SH730 grade matched to the workpiece material and the machine-tool stability to achieve efficient, repeatable results; the insert’s design supports quick replacement and minimal set-up time.

FAQ

Which turning tasks are suitable for this insert?
The TPGT 070102 SH730 insert is intended for external and internal turning; its single-sided chipbreaker and SH730 composition favour operations where tool size is small or engagement conditions change.

How is compatibility with a holder determined?
Compatibility is determined by insert form, clearance, tolerance class, fastening method, size and thickness; the TPGT070102 requires a pocket that accepts a triangular ISO 07 insert with 1.59 mm thickness and centre-hole fixation.

What advantages does the SH730 grade offer?
The SH730 grade combines a coated carbide substrate with a formulation tuned for toughness and edge stability, giving reliable wear resistance and stable cutting edges under variable loads.

Why is the 0.2 mm nose radius important?
A 0.2 mm nose radius affects surface finish and edge strength: smaller radii improve fine finishing while maintaining adequate resistance to chipping on interrupted cuts; the TPGT070102 balances those needs for precision turning.

Is the insert indexable and part of a system?
Yes — the insert is an ISO indexable turning insert designed to be used with matching holders, shims and clamps; rotation to a fresh cutting edge or replacement is part of the standard workflow.
