Sandvik Coromant 5724437 CNMG432-MM H13A Turning Insert

Product Description

The SANDVIK COROMANT 5724437 is a solid carbide turning insert designed for precision metal cutting in CNC lathe and turning center applications. Carrying the CNMG432-MM H13A designation, this insert features an 80-degree diamond shape, a neutral hand orientation, and a bright uncoated H13A carbide grade. The MM chip breaker geometry is engineered to manage chip flow and cutting forces effectively. With a 0.5000-inch inscribed circle and a 0.0313-inch corner radius, it delivers controlled, consistent cuts. Licensed machinists and CNC operators install this insert as part of the T-Max P series tooling system for external turning operations.

This insert is suited for turning steel as its primary workpiece material and stainless steel as its secondary workpiece material. It is commonly applied in production and job-shop environments running external turning, facing, and profiling operations on CNC lathes. The CNMG style with clamp and pin holding method ensures rigid seating in compatible T-Max P toolholders. The MM chip breaker makes it well matched to medium cutting conditions on steel and stainless workpieces.

Key Features

• 80-degree diamond insert shape (Shape Code C) for versatile external turning and facing
• H13A uncoated solid carbide grade optimized for steel and stainless steel cutting
• MM chip breaker geometry for effective chip control at medium cutting parameters
• Neutral hand orientation compatible with both left- and right-hand setups
• 4 cutting edges per insert for extended tooling economy
• Clamp and pin holding method provides secure, repeatable seating in T-Max P toolholders

Compatibility

Designed for use in T-Max P series toolholders accepting CNMG style inserts. ISO code CNMG 12 04 08-MM H13A. Compatible toolholders must accommodate a 0.2030-inch hole diameter and CNMG insert geometry with clamp and pin holding.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC tooling technician with the machine fully stopped and in an energy-isolated state per applicable lockout/tagout procedures. Use the correct torque wrench and clamp hardware specified by the toolholder manufacturer — do not overtighten or substitute fasteners. Inspect the insert pocket and seating surface for chips or debris before seating the new insert. When indexing to a fresh cutting edge, confirm proper edge orientation before resuming cutting operations.
