Accupro 75554832 CCMT32.51 Carbide Turning Insert

Product Description

The ACCUPRO 75554832 is a CCMT-style carbide turning insert designed for precision external turning operations on CNC and manual lathes. Built to ANSI code CCMT32.51 and ISO code CCMT09T304, this insert features an 80-degree diamond (rhombic) shape with a 7-degree relief angle and a neutral hand orientation. The PVD coating under grade ACM25P delivers a balance of wear resistance and toughness suited to steel, stainless steel, and special or super alloy workpieces. The WM+ chip breaker geometry promotes controlled chip evacuation across a range of feed rates and depths. A screw-lock holding method secures the insert in compatible toolholders for repeatable edge positioning.

This insert is intended for production and job-shop turning applications where consistent surface finish and tool life are priorities. It suits finishing to semi-finishing cuts in steel (P-class), stainless steel (M-class), and special or super alloys (S-class). The 0.40 mm corner radius makes it well matched to applications requiring a fine surface finish with minimal burr. Machinists and CNC operators working in aerospace, medical, and general precision machining will find this grade appropriate for moderate to high cutting speeds with water-soluble or neat cutting fluids.

Key Features

• ANSI code CCMT32.51 and ISO code CCMT09T304 for direct cross-reference
• PVD-coated carbide grade ACM25P — high wear resistance with retained toughness across P, M, and S workpiece classes
• 80-degree diamond insert shape with positive side clearance for clean entry angles
• WM+ chip breaker geometry for controlled chip flow across a broad feed and depth range
• 0.40 mm (0.0157 inch) corner radius supports fine to medium surface finish requirements
• Screw-lock insert holding method for secure, repeatable seating in CCMT toolholders
• Maximum depth of cut 3.00 mm (0.1181 inch) suitable for finishing and light semi-finishing passes

Compatibility

Designed for use in CCMT-style screw-lock turning toolholders accepting a 9.53 mm (0.3752 inch) inscribed circle insert with a 3.97 mm (0.1563 inch) insert thickness. Verify toolholder pocket specifications against ANSI size code 32.51 before installing.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician with the machine in a locked-out, zero-energy state before any insert change. Use the manufacturer-specified torque wrench or driver for the clamping screw to avoid cracking the carbide substrate. Inspect the toolholder pocket and seating surface for chips or wear before seating the insert. Follow your facility safety plan and applicable ANSI machining safety standards when handling sharp carbide inserts.
