Accupro 75536458 Tcmt Carbide Turning Insert

Product Description

The ACCUPRO 75536458 is a TCMT-style carbide turning insert designed for precision external and internal turning operations on CNC and manual lathes. Manufactured in the triangular insert shape (T), it carries the ANSI designation TCMT32.51 and ISO designation TCMT16T304. The insert features a CVD coating under grade ACM20P, which delivers high wear resistance suitable for finishing to semi-finishing cuts on steel and stainless steel workpieces. With a 0.40 mm (0.0157 inches) corner radius and a neutral hand orientation, this insert suits machinists and toolroom professionals who need consistent edge geometry and a reliable chip-breaking profile across moderate to high wear conditions.

The 75536458 is intended for turning applications on steel (P-class) and stainless steel (M-class) workpieces in production and job-shop environments. The WM+ chip breaker geometry is suited for moderate depth-of-cut passes where chip control is critical. Maximum depth of cut is 3.00 mm (0.1181 inches). The insert is held in place by a screw-type clamping method, compatible with standard TCMT insert pockets on turning toolholders. Three usable cutting edges per insert reduce per-edge cost in high-volume machining operations.

Key Features

• ANSI code TCMT32.51 and ISO code TCMT16T304 for standardized toolholder fitment
• CVD coating under grade ACM20P for high wear resistance on steel and stainless steel
• WM+ chip breaker for effective chip control at moderate depths of cut
• Triangular insert shape with 3 usable cutting edges per insert
• Positive side clearance (C clearance code) reduces cutting forces and tool deflection
• Neutral hand orientation for flexible application across toolholder configurations

Compatibility

Designed for use in TCMT-style screw-clamp turning toolholders accepting ANSI size code 32.51 and ISO size code 16T304 insert pockets. Suitable for steel (P) and stainless steel (M) primary workpiece material classes.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down and de-energize the machine spindle before changing inserts. Seat the insert fully in the pocket and torque the clamping screw to the toolholder manufacturer specification. Inspect the insert pocket for wear or debris before seating a new insert, and confirm correct chip breaker orientation before resuming cuts.
