Value Collection 112074037-M Turning Insert TPMR221 TCN55

Product Description

The VALUE COLLECTION 112074037-M is a solid carbide turning insert designed for precision metal-cutting operations on CNC lathes and manual turning centers. Manufactured to ANSI insert code TPMR221 and ISO insert code TPMR110304, this insert features a TiN (titanium nitride) coating that improves surface hardness and wear resistance during continuous and interrupted cutting. The triangular shape with a 60-degree included angle, positive side clearance, and 11-degree relief angle make it suited for general-purpose turning and facing applications. Installation is performed by licensed machinists and CNC operators using standard clamp-style toolholders.

This insert is intended for turning ferrous and non-ferrous workpiece materials, corresponding to primary workpiece material codes M and P. It fits into TPMR-style clamp toolholders and is appropriate for production turning environments where consistent chip control is required. The R-style chip breaker geometry is optimized for moderate depths of cut and feed rates across a range of workpiece materials. Suitable for both roughing and finishing passes depending on feed and speed selection.

Key Features

• Solid carbide substrate with TiN coating for enhanced wear resistance
• ANSI insert code TPMR221 and ISO insert code TPMR110304 for toolholder compatibility reference
• 60-degree triangle insert shape with 11-degree relief angle and positive side clearance
• Corner radius of 0.016 inches (1/64 inches) for controlled surface finish
• Inscribed circle diameter of 0.25 inches (1/4 inches)
• R-style chip breaker geometry for reliable chip evacuation
• Clamp-style insert holding method compatible with standard TPMR toolholders

Compatibility

Designed as an OEM-style replacement or equivalent turning insert for TPMR-style clamp toolholders accepting a 221 ANSI size code insert with a triangular geometry and positive clearance.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer — do not overtighten the clamp, as this can chip the insert or damage the toolholder seat. Inspect the insert pocket and seating surface for debris before installing a new insert.
