Carmex MPR5R0.2L15 Profile Boring Bar Solid Carbide

Product Description

The CARMEX MPR5R0.2L15 is a solid carbide profile boring bar engineered for internal threading and profile turning in small-bore applications. It features a minimum bore diameter of 0.2 inches and a maximum bore depth of 0.59 inches, making it well suited for tight, shallow bores where rigidity and precision are critical. The bright finish coating reduces friction and helps maintain dimensional accuracy during cutting. With a 2-inch overall length and a 0.008-inch corner radius, this bar delivers consistent performance in production and job-shop turning operations. It is installed by machinists and CNC lathe operators working with small-diameter internal profiles.

This profile boring bar is designed for right-hand cutting operations on CNC or manual lathes. It is commonly used in precision machining environments where small bore diameters and controlled depth are required, such as threading, grooving, or contouring internal features on workpieces. The 5 mm shank diameter makes it compatible with corresponding boring bar holders or tool blocks sized for that shank. Applications include production runs and prototype work in industries such as medical device, aerospace, and general precision machining.

Key Features

• Solid carbide construction for rigidity and wear resistance in small-bore cutting
• Minimum bore diameter of 0.2 inches for access to tight internal features
• Maximum bore depth of 0.59 inches suitable for shallow internal profiles
• Right-hand cutting direction for standard lathe setups
• 0.008-inch corner radius for controlled profile geometry
• Bright finish coating to reduce cutting friction

Compatibility

Designed for use with boring bar tool holders sized for a 5 mm shank diameter on CNC or manual lathes performing right-hand internal profile turning operations.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. The machine spindle must be stopped and all axes locked before mounting or removing the boring bar. Secure the shank firmly in the tool holder to the manufacturer-specified clamping torque using appropriate tooling hardware. Verify bore diameter and depth clearances against the workpiece drawing before initiating a cut.
