Carmex MPR8R0.2L15 Profile Boring Bar Solid Carbide

Product Description

The CARMEX MPR8R0.2L15 is a profile boring bar designed for internal turning and profiling operations on CNC lathes and machining centers. Machined from micrograin solid carbide with a bright finish coating, this bar delivers consistent cutting performance in tight-bore applications. It accepts a minimum bore diameter of 0.32 inches and reaches a maximum bore depth of 0.59 inches. The right-hand cutting direction suits standard spindle configurations. With an overall length of 2.5 inches and an 8 mm shank diameter, it fits a wide range of toolholding systems used by machinists in production and job-shop environments.

This profile boring bar is suited for small-bore internal profiling work on ferrous and non-ferrous materials. It performs well in applications where tight tolerances and fine surface finishes are required in bores under 0.5 inches in diameter. The 0.008-inch corner radius supports controlled chip formation and is appropriate for finishing cuts and form profiling passes. Machinists and tooling specialists working in precision turning departments will find this bar well-matched to close-tolerance internal geometry work.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in small-bore profiling
• Bright finish coating with no additional thermal coating that could alter dimensional tolerances
• 0.32-inch minimum bore diameter for access to tight internal features
• 0.59-inch maximum bore depth suitable for shallow-to-medium bore profiles
• 0.008-inch corner radius for controlled form cutting and finishing passes
• Right-hand cutting direction compatible with conventional CNC lathe setups

Compatibility

Designed as an OEM-style replacement or direct-fit tooling solution for CNC lathes and boring operations requiring an 8 mm shank diameter profile boring bar with right-hand cut geometry.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool turret is de-energized before seating or removing the boring bar. Confirm shank clamping torque meets the toolholder manufacturer specifications and that the bar is set on-center to avoid chatter or premature edge wear. Follow shop safety procedures and applicable OSHA machining standards during setup.
