Carmex 16IR/EL0.077BXC Grooving Insert Solid Carbide Tin

Product Description

The CARMEX 16IR/EL0.077BXC is a solid carbide grooving insert designed for precision internal and external grooving operations on CNC lathes and turning centers. Coated with TiN via PVD process and manufactured to the BXC grade, this insert delivers consistent performance on cast iron and steel workpieces. It features a 0.077 inch cutting width, a maximum depth of cut of 0.079 inches, and a positive 15-degree rake angle for clean chip formation and reduced cutting forces. Machining professionals and tooling technicians use this insert in production turning environments where dimensional accuracy and surface finish are critical.

This grooving insert is suited for both left-hand and right-hand applications, making it versatile across a range of turning setups. It is designed for use on primary workpiece materials including steel (P) and cast iron (K) per ISO material classification. The Series 16 designation corresponds to a 3/8 inch inscribed circle and an overall length of 16.00 mm. It is well suited for shops running medium to high production volumes on ferrous materials where a reliable, coated carbide insert is required.

Key Features

• Solid carbide construction with PVD-applied TiN coating for extended wear resistance
• 0.077 inch cutting width with a maximum depth of cut range of 0.075 to 0.100 inches
• Positive 15-degree rake angle reduces cutting forces and improves chip control
• Compatible with both left-hand and right-hand grooving operations
• C6 material grade suitable for cast iron and steel per ISO K and P classifications
• 10-degree external relief angle and 15-degree internal relief angle for clearance control

Compatibility

Designed for use with Series 16 grooving toolholders accepting a 3/8 inch inscribed circle insert with a 0.157 inch hole diameter. Verify toolholder seat geometry and series compatibility before installation.

Installation Notes

Insert installation and replacement should be performed by a qualified machinist or tooling technician with the machine fully powered down and spindle locked. Use the correct torque wrench and insert screw per the toolholder manufacturer specification to avoid seat damage or insert fracture. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert. Follow applicable shop safety protocols and machine tool manufacturer guidelines during all tooling changes.
