Accupro 75542704 CCMT32.52 Carbide Turning Insert

Product Description

The ACCUPRO 75542704 is a carbide turning insert designed for precision external and internal turning operations on CNC and manual lathes. Conforming to ANSI code CCMT32.52 and ISO code CCMT09T308, this insert features an 80-degree diamond (rhombic) shape, a 7-degree relief angle, and a PVD coating applied over a ACM25P carbide grade substrate. The chip breaker geometry is WSF+, engineered to manage chip control across a range of depths of cut up to 0.0886 inches (2.25 mm). The corner radius is 0.0315 inches (0.80 mm). Insert hand is neutral, and the side clearance is positive.

This insert is suited for turning steel, stainless steel, and special or super alloys in production and job-shop environments. The ACM25P grade with PVD coating provides high wear resistance across steel (P) and stainless steel (M) applications, and moderate wear resistance with toughness for super alloys (S). Typical use cases include finish and semi-finish turning passes where consistent edge life and dimensional accuracy are required. It is held in place by a screw-type clamping method, making it compatible with standard CCMT-style tool holders used in most turning centers and engine lathes.

Key Features

• ANSI code CCMT32.52 and ISO code CCMT09T308 for direct cross-reference ordering
• ACM25P carbide grade with PVD coating for high wear resistance in steel and stainless steel machining
• WSF+ chip breaker geometry supports controlled chip formation at moderate to light depths of cut
• 80-degree diamond insert shape (C) with positive side clearance reduces cutting forces
• Neutral hand insert fits left-hand, right-hand, and straight turning tool holders
• Screw-type holding method compatible with standard CCMT boring bars and turning tool holders

Compatibility

Designed as a direct replacement for CCMT32.52 or CCMT09T308 style inserts in screw-clamp turning tool holders rated for that insert geometry. No specific brand model numbers were provided in the product data.

Installation Notes

This insert is installed by a machinist or toolroom technician into a compatible CCMT-style screw-clamp tool holder. Before changing inserts, confirm the machine is in an E-stop or powered-off state and the spindle is locked. Use the appropriate Torx or hex key to seat and torque the clamp screw per the tool holder manufacturer specification. Inspect the pocket seating surface for chips or debris before seating the new insert to ensure proper edge geometry and runout.
