Carmex MPR2R0.15L10 Profile Boring Bar Solid Carbide

Product Description

The CARMEX MPR2R0.15L10 is a profile boring bar designed for internal turning and profiling operations in small-bore applications. Constructed from micrograin solid carbide with a bright finish coating, this bar delivers consistent edge integrity and wear resistance in demanding cutting conditions. It has a minimum bore diameter of 0.08 inches, a maximum bore depth of 0.39 inches, and a corner radius of 0.006 inches. The right-hand cutting direction suits standard lathe and CNC turning setups. At 1.5 inches overall length, it fits compact tooling configurations where rigidity and precision in tight bores are critical. Machinists and toolroom technicians are the primary users.

This boring bar is suited for internal profiling and contour boring in small-diameter bores on CNC lathes and manual turning centers. It is applicable in precision machining environments including job shops, production turning, and tool and die operations where tight tolerances and fine surface finishes are required. The 3.00 mm shank diameter is sized for small-bore toolholders compatible with that shank dimension. Applications include threading relief grooves, chamfers, and internal contour features in ferrous and non-ferrous materials.

Key Features

• Micrograin solid carbide construction for enhanced hardness and edge retention
• Bright finish coating provides a smooth, uncoated cutting edge suitable for non-ferrous and ferrous materials
• 0.08 inches minimum bore diameter enables work in very small internal diameters
• 0.006 inches corner radius for fine profiling and contour accuracy
• Right-hand cutting direction for standard toolholder orientation
• Compact 1.5 inches overall length reduces overhang and improves rigidity

Compatibility

Designed for use with small-bore internal turning toolholders accepting a 3.00 mm shank diameter in CNC and manual lathe applications.

Installation Notes

Installation of boring bars is performed by machinists and CNC toolroom technicians. Power down and lock out the machine spindle before setting or changing tooling. Secure the shank firmly in the toolholder to the appropriate clamping depth to minimize overhang and chatter. Verify bore clearance and cutting direction before initiating the first pass.
