Value Collection TCN19320E Turning Insert SPMR322 TCN55

Product Description

The VALUE COLLECTION TCN19320E is a solid carbide turning insert designed for precision metal-cutting operations on CNC and manual lathes. Conforming to ANSI Insert Code SPMR322 and ISO Insert Code SPMR090308, this insert features a square shape with a 90-degree included angle, an 11-degree relief angle, and a positive side clearance geometry. The cutting edges are TiN (titanium nitride) coated under manufacturer grade TCN55, providing improved wear resistance and surface hardness over uncoated carbide. Installed by machinists and tool-room professionals, this insert suits turning, facing, and light profiling passes on ferrous and non-ferrous workpiece materials.

This insert is suited for general-purpose external turning applications. The SPMR-style geometry with a clamp-type holding method fits standard SPMR toolholders used in production and job-shop environments. With a material grade rating of C5 and primary workpiece material codes M and P, it is appropriate for machining medium-carbon steels, alloy steels, and similar materials. The R-type chip breaker geometry helps manage chip flow during continuous cutting passes, reducing the risk of chip re-cutting and workpiece surface damage.

Key Features

• Solid carbide substrate with TiN coating under manufacturer grade TCN55 for extended tool life
• ANSI Insert Code SPMR322 and ISO Insert Code SPMR090308 for standardized toolholder compatibility
• 90-degree square insert shape with 11-degree relief angle and positive side clearance
• 1/32 inch (0.0313 inch) corner radius for light-profiling and finishing-pass capability
• R-type chip breaker for active chip control during continuous turning operations
• Clamp-style insert holding method compatible with standard SPMR toolholders

Compatibility

Designed for use in standard SPMR-style clamp-type toolholders accepting a square insert with ANSI size code 322 and ISO size code 090308. Verify toolholder pocket dimensions and insert seating before use.

Installation Notes

This insert is installed by machinists in accordance with the toolholder manufacturer's clamping torque and seating specifications. Always power down and lock out the machine spindle before changing inserts. Inspect the toolholder pocket and clamp for chips or damage prior to seating the insert. Wear cut-resistant gloves when handling carbide inserts, as edges are sharp and carbide is brittle.
