Value Collection ICP75410C Turning Insert DCMT21.51 TCN55

Product Description

The VALUE COLLECTION ICP75410C is a solid carbide turning insert designed for single-point lathe and turning center operations. It carries the ANSI code DCMT21.51 and ISO code DCMT070204, identifying it as a 55-degree diamond-shaped (rhombic) insert with a positive side clearance and a screw-holding method. The insert is TiN coated under manufacturer grade TCN55, which improves surface hardness and wear resistance during metal cutting. With a 1/4-inch inscribed circle and a 1/64-inch corner radius, this insert is suited for finishing and light semi-finishing passes on a variety of workpiece materials. Licensed machinists and CNC lathe operators are the primary installers and users of this insert.

This insert is intended for use in external and internal turning applications on CNC and manual lathes. It is appropriate for machining steel, stainless steel, and other materials designated under primary workpiece material codes M and P. The positive relief angle of 7 degrees and the chip breaker style T contribute to controlled chip evacuation during light-to-medium cutting passes. The insert fits standard DCMT-style toolholders with a screw-clamp retention system.

Key Features

• ANSI code DCMT21.51, ISO code DCMT070204 for cross-reference ordering
• 55-degree diamond (rhombic) insert shape for versatile turning and profiling
• TiN coating under grade TCN55 for improved wear resistance
• Positive side clearance with 7-degree relief angle reduces cutting forces
• 1/64-inch corner radius suited for finishing and light semi-finishing operations
• Screw-clamp holding method for secure, repeatable seating in compatible toolholders

Compatibility

Designed as an OEM-style replacement or standard fit for DCMT-style screw-clamp toolholders accepting a size 21.51 insert with a 0.110-inch hole diameter.

Installation Notes

Insert replacement should be performed by a qualified machinist or CNC operator with the machine powered down and the spindle locked. Use the appropriate torque wrench and insert screw specified by the toolholder manufacturer when securing the screw-clamp. Inspect the toolholder pocket and seating surface for chips or damage before seating the new insert. Do not overtighten the clamping screw, as this can fracture the carbide insert.
