Carmex 20800013 Grooving Insert 0.089 in Bxc Carbide Series 16

Product Description

The CARMEX 20800013 is a carbide grooving insert designed for external and internal grooving operations on CNC lathes and turning centers. Built to Series 16 specifications with a BXC manufacturer grade, this insert features a TiN (titanium nitride) coating applied via a PVD process, which extends tool life when cutting cast iron and steel. It carries a 0.089-inch cutting width, a positive rake angle of 15 degrees, and an inscribed circle of 3/8 inch. The insert is suited for both left-hand and right-hand tooling setups. Licensed machinists and CNC operators handling production turning work are the primary installers of this insert type.

This insert is rated for use on cast iron and steel workpieces, corresponding to ISO material grades K and P. It is designed for grooving applications where the maximum depth of cut falls in the 0.075-inch to 0.100-inch range. The positive rake geometry and 10-degree external relief angle support clean chip evacuation and reduced cutting forces on ferrous materials. It fits standard Series 16 insert pockets and toolholders designed for the 16IR/EL insert style, making it a practical drop-in option for shops already running Series 16 tooling systems.

Key Features

• Carbide substrate with PVD-applied TiN coating for extended wear resistance on ferrous materials
• 0.089-inch cutting width with a maximum depth of cut range of 0.075 to 0.100 inches
• Positive rake angle (15 degrees) reduces cutting forces and supports clean chip flow
• Compatible with both left-hand and right-hand toolholder setups
• 0.004-inch corner radius for controlled groove geometry without a full radius profile
• Meets ISO standards; rated for ISO material grades K (cast iron) and P (steel)

Compatibility

Designed for use in Series 16 toolholders accepting the 16IR/EL insert style. Suitable for external and internal grooving operations on cast iron and steel workpieces in standard CNC turning applications.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Always power down and lock out the machine spindle before seating or replacing inserts. Use the correct torque wrench and insert clamp hardware specified for Series 16 pockets to avoid insert movement or pocket damage. Inspect the toolholder pocket for wear or debris before seating a new insert.
