Accupro 75283184 Turning Insert Tcmt Carbide Triangle

Product Description

The ACCUPRO 75283184 is a TCMT-style carbide turning insert designed for external and internal turning operations on CNC and manual lathes. It carries ANSI insert code TCMT21.51 and ISO insert code TCMT110204. The triangular insert geometry features a 60-degree included angle, a 7-degree relief angle with positive side clearance, and a 0.0157-inch (0.40 mm) corner radius. Grade ACM35P with PVD coating provides moderate wear resistance and toughness, making it well suited for machining steel (P) and stainless steel (M) workpiece materials. The insert is held by screw clamping and delivers neutral hand cutting action.

This insert is applied in production turning environments where steel and stainless steel are the primary workpiece materials. The WM+ chip breaker geometry supports moderate cutting conditions. With three usable cutting edges per insert and a maximum depth of cut of 0.1181 inches (3.00 mm), it is suited for medium finishing to light roughing passes. Machinists and CNC programmers working in job shops, aerospace, and general manufacturing will find this insert appropriate for consistent, repeatable metal removal on those material classes.

Key Features

• ANSI code TCMT21.51 and ISO code TCMT110204 for standardized toolholder compatibility
• Grade ACM35P with PVD coating for steel and stainless steel applications
• Triangular insert shape with 3 cutting edges maximizes insert utilization
• WM+ chip breaker geometry supports moderate wear resistance and toughness balance
• Positive side clearance reduces cutting forces and minimizes workpiece deflection
• Screw-holding method provides secure, repeatable insert indexing

Compatibility

Designed as a screw-clamp TCMT-style replacement insert for toolholders conforming to ANSI TCMT21.51 and ISO TCMT110204 specifications. Verify toolholder bore diameter against the 0.1122-inch hole diameter before installation.

Installation Notes

Turning insert replacement is performed by qualified machinists or CNC technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct Torx or hex key specified by the toolholder manufacturer to seat the clamping screw. Inspect the insert pocket and seating surfaces for chips or debris before installing a new edge to ensure proper seating and tool life.
