Carmex MPR5R0.2L22 Profile Boring Bar Solid Carbide

Product Description

The CARMEX MPR5R0.2L22 is a solid carbide profile boring bar designed for internal threading and profiling operations on CNC lathes and turning centers. It accepts a minimum bore diameter of 0.2 inches and reaches a maximum bore depth of 0.87 inches, making it well suited for small-bore finish work where rigidity and precision are critical. The bright finish coating reduces friction and aids in chip evacuation. With a 0.008-inch corner radius, this bar is built for threading and groove profile passes that demand tight tolerances and consistent tool geometry.

This boring bar is used in precision machining environments including job shops, production turning operations, and aerospace or medical component manufacturing where small internal features require controlled depth and accurate profile reproduction. The right-hand cutting direction suits standard lathe setups. The 5 mm shank diameter fits compatible toolholding systems designed for that shank size, and the 2-inch overall length provides a compact, stable reach for shallow-bore applications.

Key Features

• Solid carbide construction for rigidity and wear resistance in small-bore profiling
• 0.2-inch minimum bore diameter for tight internal feature access
• 0.87-inch maximum bore depth for controlled shallow-bore reach
• 0.008-inch corner radius for precise profile and threading passes
• Bright finish coating to reduce friction and assist chip flow
• Right-hand cut orientation for standard lathe configuration

Compatibility

Designed for use in toolholding systems that accept a 5 mm shank diameter boring bar for profile and threading operations on CNC or manual lathes.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down the machine and engage the spindle lock before seating or removing the boring bar from its holder. Ensure the shank is fully seated and properly clamped to the toolholder torque specification called out by the holder manufacturer. Verify tool overhang does not exceed the recommended length-to-diameter ratio for the workpiece material to prevent chatter and maintain dimensional accuracy.
