Value Collection ICP65130C Turning Insert VBMT221 TCN55

Product Description

The VALUE COLLECTION ICP65130C is a solid carbide turning insert designed for external and internal turning operations on CNC lathes and manual turning centers. Conforming to ANSI insert code VBMT221 and ISO insert code VBMT110304, this insert features a 35-degree diamond (rhombic) shape with a positive side clearance angle of 5 degrees. The substrate is carbide grade C5, coated with titanium nitride (TiN) to improve surface hardness and wear resistance. A 0.0156-inch corner radius provides a sharp, defined cutting edge suited to finishing and light roughing passes. Licensed machinists and CNC operators working with ferrous and stainless alloys are the typical installers of this insert.

This insert is appropriate for turning applications on workpiece material codes M and P, which correspond broadly to stainless steels and carbon and alloy steels. The VBMT style with a screw-lock holding method seats securely in compatible VBMT-style toolholders. The chip breaker designation T is integrated into the insert geometry to manage chip formation during continuous cuts. This insert is sold individually but carries a minimum order quantity of 10 units, making it suited for shop restocking or toolcrib replenishment.

Key Features

• ANSI code VBMT221 and ISO code VBMT110304 for broad toolholder compatibility
• 35-degree diamond (rhombic) insert shape for tight-clearance and profiling cuts
• TiN coating over C5 carbide substrate for improved wear resistance on steel alloys
• 0.0156-inch (1/64 inch) corner radius for defined edge geometry on finishing passes
• Positive 5-degree relief angle reduces cutting forces on workpiece
• Screw-lock insert holding method for secure, repeatable seating

Compatibility

Designed as an OEM-style replacement insert for VBMT-style toolholders accepting ANSI size code 221 inserts with a screw-lock holding method.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the toolholder is clear of the workpiece before swapping inserts. Use the appropriate Torx or hex key to torque the clamping screw — refer to the toolholder manufacturer specification for fastener torque. Inspect the insert pocket and seating surface for chips or debris before seating the new insert to prevent rocking or premature edge failure.
