Accupro 75392894 Scmt Carbide Turning Insert Cvd 4-edge

Product Description

The ACCUPRO 75392894 is a carbide turning insert designed for precision external turning operations on CNC and manual lathes. Following the SCMT09T304 ISO geometry, this insert features a square shape (S) with a 90-degree included angle, a 7-degree relief angle, and a 0.40 mm (0.0157 inch) corner radius. The ACP25M grade substrate carries a CVD coating and delivers a balance of wear resistance and toughness suited for steel, stainless steel, and cast iron workpiece materials. Four usable cutting edges per insert reduce per-edge tooling cost in production environments. A neutral hand orientation and screw-in holding method make this insert compatible with a broad range of SCMT-style toolholders.

This insert is well suited for general-purpose turning on ferrous materials in both job shop and production settings. It is used in turning centers and engine lathes where consistent surface finish and dimensional accuracy are required. The WM+ chip breaker geometry is designed to handle a range of feed rates and depths of cut, making it adaptable across roughing and semi-finishing passes. Machinists and CNC operators working steel (P), stainless steel (M), and cast iron (K) applications will find the ACP25M grade appropriate for moderate to high cutting demands. Maximum depth of cut is 3.00 mm (0.1181 inches).

Key Features

• SCMT09T304 ISO geometry with 90-degree included angle and 7-degree relief for positive clearance
• CVD coating on ACP25M carbide grade for high wear resistance across steel, stainless, and cast iron
• Four cutting edges per insert for extended tool life and lower cost per edge
• WM+ chip breaker supports both semi-finishing and moderate roughing applications
• Screw-in holding method with 0.1772-inch hole diameter for secure, repeatable clamping
• Neutral hand orientation fits a wide range of standard SCMT toolholders

Compatibility

Designed as an OEM-style replacement insert for SCMT-style turning toolholders accepting the SCMT09T304 ISO size code. Verify toolholder pocket specifications before ordering.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Always index or replace inserts with the machine powered down and the spindle locked. Use the appropriate torque wrench and screw driver for the insert screw to avoid stripping the clamping hardware. Inspect the toolholder pocket for wear or debris before seating a new insert to ensure proper contact and runout.
