Sandvik Coromant 5754934 TPG322 H13A Turning Insert

Product Description

The SANDVIK COROMANT 5754934 is a solid carbide uncoated turning insert in the TPG322 H13A grade, designed for precision metal-cutting operations on CNC and manual lathes. This triangular insert carries a 60-degree included angle, a 3/8-inch inscribed circle (IC), and a 1/32-inch corner radius (0.0313 inches). The H13A grade is an uncoated bright carbide suited for applications where coating would interfere with edge sharpness or where the workpiece material demands a keen, unlubricated cutting edge. Insert thickness is 1/8 inch (0.125 inches) and overall insert length measures 0.618 inches. Installation and replacement are performed by licensed machinists and CNC tooling technicians.

This insert is intended for turning operations in general machining environments, including finishing and semi-finishing passes on non-ferrous metals, cast iron, and certain hardened materials where uncoated carbide performs optimally. The clamp-style holding method (insert style TPGN) suits standard triangular toolholders with a P clearance code and G tolerance class. The ISO designation for this insert is TPGN 16 03 08 H13A, which allows cross-referencing with compatible toolholder systems. No chip breaker geometry is present on this insert, making it appropriate for controlled-depth finishing applications where a flat rake face is preferred.

Key Features

• Solid carbide construction with bright uncoated finish for sharp, consistent cutting edges
• 60-degree triangular insert shape (Insert Shape Code: T) with 11-degree relief angle
• 3/8-inch inscribed circle (0.3750 inches) for toolholder compatibility sizing
• 1/32-inch corner radius (0.0313 inches) suited for fine finishing passes
• No chip breaker (Code: N) for flat rake face performance on finishing cuts
• ISO Code TPGN 16 03 08 H13A enables direct cross-reference with ISO toolholder systems

Compatibility

Designed for use in TPGN-style clamp-type toolholders accepting a 3/8-inch IC triangular insert with P clearance and G tolerance. The ISO designation TPGN 16 03 08 H13A should be used to verify toolholder compatibility before installation.

Installation Notes

Insert replacement should be performed by a qualified machinist or tooling technician with the machine spindle fully stopped and all energy sources locked out per applicable OSHA lockout/tagout procedures. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer when seating the insert. Inspect the insert pocket and clamp for wear or debris before installing a new insert. Never attempt to re-grind or modify this solid carbide insert in the field.
