Accupro 75271619 CCMT32.51 Carbide Turning Insert

Product Description

The ACCUPRO 75271619 is a CCMT-style carbide turning insert designed for precision external turning operations on CNC and manual lathes. It carries ANSI insert code CCMT32.51 and ISO insert code CCMT09T304, with an 80-degree diamond (rhombic) insert shape and a 7-degree relief angle. The insert is manufactured from carbide with a CVD coating and falls under the ACM20P grade, which delivers high to moderate wear resistance and toughness. With a corner radius of 0.40 mm (0.0157 inches) and a neutral hand orientation, it suits finishing and semi-finishing passes where dimensional accuracy is critical. Licensed HVAC, machining, and tool crib professionals managing lathe tooling will find this insert a direct fit for productivity-focused turning setups.

This insert is engineered for steel (P) and stainless steel (M) workpiece materials, covering applications that demand high wear resistance through moderate wear resistance and toughness. The WSF+ chip breaker geometry promotes reliable chip control during continuous or interrupted cuts. With a maximum depth of cut of 2.25 mm (0.0886 inches) and two available cutting edges per insert, it is suited for production turning environments where tool life and consistency are priorities. It is held in place by a screw-clamping insert holding method.

Key Features

• CCMT insert style with 80-degree diamond (rhombic) shape for versatile external turning
• CVD coating on ACM20P carbide grade for high wear resistance in steel and stainless steel applications
• WSF+ chip breaker geometry for controlled chip evacuation in finishing and semi-finishing cuts
• Neutral hand orientation compatible with standard CCMT toolholders
• Two usable cutting edges per insert, reducing per-edge tooling cost
• Screw-clamping holding method for secure, repeatable seating in compatible toolholders

Compatibility

Designed as an OEM-style replacement turning insert for CCMT-style screw-clamp toolholders accepting ANSI CCMT32.51 or ISO CCMT09T304 inserts. Primary workpiece material codes P and M confirm suitability for steel and stainless steel turning operations.

Installation Notes

Installation is performed by machinists or tooling technicians on manual or CNC lathes. Power down and lock out the machine spindle before seating or indexing the insert. Use the correct Torx or hex key for the insert clamping screw and avoid overtightening, which can crack the carbide. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert.
