Value Collection ICP14405M Turning Insert DPMT21.505 TCN55

Product Description

The VALUE COLLECTION ICP14405M is a solid carbide turning insert designed for precision metal cutting operations on CNC lathes and turning centers. Manufactured to ANSI insert code DPMT21.50.5 and ISO insert code DPMT070202, this insert features a 55-degree diamond (rhombic) shape with a positive side clearance and an 11-degree relief angle. The TiN (titanium nitride) coating in manufacturer grade TCN55 provides surface hardness and wear resistance suited for general-purpose turning. With a 0.2500-inch inscribed circle and a 0.008-inch corner radius, the insert delivers controlled cutting geometry for ferrous and non-ferrous applications. It is held in the toolholder via screw clamping and is compatible with standard DPMT-style pockets.

This insert is intended for use in production turning environments where consistent chip control and dimensional accuracy are required. The DPMT style with a positive clearance angle reduces cutting forces, making it appropriate for medium-duty turning of steels and stainless steels. The TCN55 grade with TiN coating suits a range of primary workpiece material codes M and P, covering austenitic stainless steels and carbon or alloy steels. Machinists, tool-and-die shops, and metalworking facilities running high-volume turning programs will find this insert a cost-effective fit for standard toolholder setups.

Key Features

• 55-degree diamond (rhombic) insert shape (ANSI code D) for accessible entry angles and versatile turning profiles
• TiN coating in grade TCN55 for improved surface hardness and extended tool life on steel and stainless applications
• Positive side clearance (clearance code P) reduces cutting forces and minimizes workpiece deflection
• 0.008-inch corner radius provides a balance of edge strength and surface finish quality
• Screw-held mounting (DPMT style) ensures repeatable insert indexing and secure clamping in compatible toolholders
• 0.0938-inch insert thickness and 0.1100-inch hole diameter conform to standard DPMT pocket geometry

Compatibility

Designed as a direct-fit replacement for DPMT21.50.5 style insert pockets on screw-clamp turning toolholders accepting a 0.2500-inch inscribed circle, 55-degree diamond inserts with positive clearance geometry.

Installation Notes

Insert replacement should be performed with the machine powered off and all axes locked. Use the correct Torx or hex key specified by the toolholder manufacturer when tightening the clamp screw — do not over-torque, as this can crack the carbide insert. Inspect the toolholder pocket and seating surface for chips or wear before indexing or replacing the insert. Handle carbide inserts with care; edges are brittle and can chip if dropped on hard surfaces.
