Value Collection ICP65105L Turning Insert TPMT32.51 TCN55

Product Description

The VALUE COLLECTION ICP65105L is a solid carbide turning insert designed for precision lathe and turning center operations. Conforming to ANSI insert code TPMT32.51 and ISO insert code TPMT16T304, this triangular insert features a titanium nitride (TiN) coating that extends tool life and reduces built-up edge on ferrous and stainless workpiece materials. With a 3/8-inch inscribed circle, a 5/32-inch insert thickness, and a 1/64-inch corner radius, it is suited for finishing and light roughing passes. Machinists, toolroom operators, and CNC turning technicians install this insert into compatible TPMT-style screw-lock toolholders.

This insert is intended for turning applications on primary workpiece material codes M and P, covering stainless steels, carbon steels, and low-alloy steels. The positive side clearance (clearance code P, tolerance code M) supports free-cutting action and reduces radial cutting forces, making it appropriate for slender workpieces and lighter machine tools. The TCN55 manufacturer grade with TiN coating and T-style chip breaker makes it a practical choice for medium-speed finishing operations in production and job-shop environments.

Key Features

• Solid carbide substrate with TiN coating for improved wear resistance on steels and stainless steels
• ANSI code TPMT32.51 and ISO code TPMT16T304 for straightforward toolholder matching
• 60-degree triangular insert shape (T) provides three usable cutting edges per insert
• Positive side clearance geometry reduces cutting forces on light to medium turning operations
• T-style chip breaker aids chip control during finishing and light roughing passes
• Screw-lock holding method ensures positive, repeatable seating in TPMT toolholders

Compatibility

Designed as an OEM-style replacement or direct-fit insert for TPMT-style screw-lock turning toolholders accepting ANSI size code 32.51 (ISO size code 16T304) triangular inserts with a 0.173-inch hole diameter.

Installation Notes

Installation is performed by qualified machinists or CNC toolroom technicians. Power down and lock out the machine spindle before seating or indexing the insert. Use the manufacturer-specified insert screw and a calibrated torx or hex key to secure the insert without over-torquing the clamp screw. Inspect the insert pocket and seating surface for chips or debris before installation to ensure accurate tool-height repeatability.
