Accupro 75469247 Tcmt Carbide Turning Insert Cvd

Product Description

The ACCUPRO 75469247 is a carbide turning insert designed for precision metal-cutting operations on CNC and manual lathes. Manufactured to ANSI code TCMT21.52 and ISO code TCMT110208, this TCMT-style insert features a triangular shape with a 60-degree included angle, a 7-degree relief angle, and a 0.0315 inch (0.80 mm) corner radius. The CVD coating and grade ACP25M substrate provide a balance of wear resistance and toughness suited to steel, stainless steel, and cast iron workpiece materials. Machinists and CNC operators install this insert as a screw-held replacement in compatible TCMT toolholders.

This insert is appropriate for turning operations across a range of workpiece materials including steel (P), stainless steel (M), and cast iron (K) applications. With a maximum depth of cut of 0.1181 inch (3.00 mm) and a WM+ chip breaker geometry, it is suited for medium finishing to moderate roughing passes. The neutral hand orientation makes it adaptable to both right-hand and left-hand toolholder configurations without repositioning. It is commonly used in production turning environments and job shop applications where consistent tool life and predictable chip control are priorities.

Key Features

• ANSI insert code TCMT21.52 and ISO code TCMT110208 for standardized toolholder compatibility
• CVD coating on ACP25M carbide grade for high wear resistance across steel, stainless steel, and cast iron
• Triangular insert shape with 60-degree included angle and positive side clearance for clean cutting geometry
• WM+ chip breaker geometry supports medium finishing through moderate roughing depths of cut
• Neutral hand orientation fits both right-hand and left-hand TCMT screw-lock toolholders
• 3 usable cutting edges per insert for extended service life per unit

Compatibility

Designed as an OEM-style replacement insert for TCMT-style screw-lock toolholders conforming to ANSI code TCMT21.52 and ISO code TCMT110208. Confirm toolholder seat dimensions and insert pocket geometry before installation.

Installation Notes

Insert replacement should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before accessing the toolholder. Use the appropriate Torx or hex key to remove the clamping screw; do not over-torque the screw when seating the new insert, as this can crack the carbide. Inspect the insert pocket and seating surface for chips or debris before installing the replacement edge.
