Value Collection ICP14412B Turning Insert DPMT21.51 TCN55

Product Description

The VALUE COLLECTION ICP14412B is a solid carbide turning insert designed for precision metal cutting applications on CNC lathes and manual turning centers. Manufactured to ANSI insert code DPMT21.51 and ISO insert code DPMT070204, this insert features a 55-degree diamond (rhombic) shape with a positive side clearance and an 11-degree relief angle. A titanium nitride (TiN) coating improves surface hardness and wear resistance. The 1/4-inch inscribed circle and 1/64-inch corner radius make it suited for finishing and semi-finishing passes. Installation is performed by machinists and CNC operators in job shop, production, and maintenance machining environments.

This insert is intended for use in turning operations on workpiece materials classified under ISO material groups M and P, which correspond to stainless steels and carbon and alloy steels. It fits toolholders designed for DPMT-style screw-lock inserts with a positive clearance geometry. The TCN55 manufacturer grade with TiN coating is appropriate for moderate cutting speeds and general-purpose turning where a balance of toughness and wear resistance is needed. Typical applications include external turning, facing, and light profiling on medium-sized workpieces.

Key Features

• Solid carbide construction with TiN coating for improved wear resistance
• 55-degree diamond insert shape (ANSI code DPMT21.51, ISO code DPMT070204)
• Positive side clearance with 11-degree relief angle reduces cutting forces
• 1/4-inch inscribed circle and 1/64-inch corner radius for finishing and semi-finishing
• Screw-lock holding method for secure, repeatable seating in compatible toolholders
• Material grade C5 carbide suitable for ISO M and P workpiece materials

Compatibility

Designed as a direct-fit replacement for DPMT21.51-style turning insert seats in screw-lock toolholders accepting a positive-clearance, 55-degree diamond insert with a 0.110-inch hole diameter.

Installation Notes

This insert is installed and indexed by machining professionals including CNC operators and tool-and-die machinists. Before changing inserts, power down the machine and engage all locks per shop safety protocol. Use the appropriate torx or hex key for the clamping screw and seat the insert fully against the pocket before tightening. Inspect the insert pocket and clamping screw for wear or damage each time an insert is indexed or replaced.
