Accupro 75356105 TNMG432 Carbide Turning Insert ACP25M

Product Description

The ACCUPRO 75356105 is a TNMG432 triangular carbide turning insert designed for general-purpose external and internal turning operations on CNC and manual lathes. It carries an ACP25M grade designation with a CVD coating, making it well-suited for machining steel, stainless steel, and cast iron across a broad range of cutting conditions. The insert features a neutral hand orientation, a 0-degree relief angle with negative side clearance, and a 1.20 mm (0.0472 inches) corner radius. Six usable cutting edges per insert extend tool life and reduce per-edge cost. This insert is a direct consumable for machinists, tool-and-die shops, and production turning operations.

The 75356105 is used in turning centers and engine lathes for roughing through semi-finishing passes on steel (P), stainless steel (M), and cast iron (K) workpiece materials. Its chip breaker geometry, designated 909+, supports controlled chip evacuation across those material groups. The maximum depth of cut reaches 6.50 mm (0.2559 inches), making it appropriate for medium to heavy stock removal. The insert seats in any TNMG-style toolholder accepting a 22-series insert and can be retained by clamp, lever lock, pin, or screw holding methods.

Installation Notes

Insert seating and replacement is performed by qualified machinists or toolroom technicians. Always de-energize and lock out the machine before indexing or replacing inserts. Ensure the insert pocket and seating surface are clean and free of chips before clamping. Follow the toolholder manufacturer's clamping torque and holding-method specifications when securing the insert.
