Value Collection ICP65090M Turning Insert TPMT21.505 TCN55

Product Description

The VALUE COLLECTION ICP65090M is a solid carbide turning insert designed for precision metal cutting on CNC lathes and manual turning centers. It carries the ANSI insert code TPMT21.50.5 and ISO insert code TPMT110202, identifying it as a triangular TPMT-style insert with a 60-degree included angle and an 11-degree positive relief angle. The cutting surface is TiN-coated under manufacturer grade TCN55, which improves wear resistance and extends tool life in general-purpose turning applications. The insert has a 1/4-inch (0.2500 inch) inscribed circle and a 0.008-inch corner radius. It is held in place by a screw-clamp method, consistent with standard TPMT toolholders.

This insert is suited for turning operations on steel and stainless steel workpiece materials, as indicated by primary workpiece material codes M and P. It fits residential and commercial machine shop environments as well as production floor turning operations. The positive side clearance geometry reduces cutting forces and makes it a practical choice for medium-finish and semi-finish turning passes. Machinists and CNC operators handling general-purpose external and internal turning will find this insert a direct-fit option for compatible TPMT screw-on toolholders.

Key Features

• Solid carbide substrate with TiN coating under grade TCN55 for improved wear resistance
• 60-degree triangular insert shape with 11-degree positive relief angle reduces cutting forces
• 0.008-inch corner radius suitable for semi-finish and medium-finish turning
• Screw-clamp holding method compatible with standard TPMT toolholder seats
• Positive side clearance geometry for clean chip evacuation

Compatibility

Designed as a direct-fit replacement for screw-clamp TPMT-style toolholders accepting a 1/4-inch inscribed circle triangular insert with ANSI size code 21.50.5 and ISO size code 110202.

Installation Notes

Insert replacement should be performed by a qualified machinist or CNC operator with the machine fully powered down and the spindle locked. Use the appropriate torx or hex key to seat the screw clamp to the toolholder manufacturer specification. Inspect the toolholder pocket for wear or debris before seating a new insert. Dispose of worn inserts in accordance with applicable shop safety and waste disposal procedures.
