Carmex MTR8R0.2L15 Boring Bar Solid Carbide Right Hand

Product Description

The CARMEX MTR8R0.2L15 is a solid carbide boring bar designed for internal turning and bore finishing operations on CNC lathes and turning centers. It accepts a minimum bore diameter of 0.32 inches and reaches a maximum bore depth of 0.59 inches, making it well suited for small-diameter, close-tolerance work. The right-hand cutting direction is standard for conventional lathe spindle rotation. The bright finish coating leaves the carbide substrate exposed for direct inspection and is typical of uncoated precision boring tooling. Machinists and toolroom technicians working in production or job-shop environments rely on this style of bar for repeatability in tight bores.

This boring bar is used in applications requiring precise internal diameter control on ferrous and non-ferrous materials. The 8.00 mm shank diameter fits compatible boring bar holders and modular quick-change tooling systems. With a 2.5-inch overall length and a 0.008-inch corner radius, it suits finish-boring passes where edge geometry and runout control are critical. It is appropriate for both production runs and prototype work where bore geometry must meet close tolerances.

Key Features

• Solid carbide construction for rigidity and wear resistance in small-bore applications
• Minimum bore diameter of 0.32 inches enables work in tight internal features
• Maximum bore depth of 0.59 inches suitable for shallow-to-medium blind and through bores
• Right-hand cutting direction for standard CNC lathe spindle rotation
• 0.008-inch corner radius for controlled surface finish and reduced stress concentration
• Bright finish coating for clear visual inspection of cutting edge condition

Compatibility

Designed for use in boring bar holders and modular tooling systems that accept an 8.00 mm shank diameter on CNC lathes and turning centers.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and the turret is in a safe index position before mounting or removing the boring bar. Verify shank seating and clamping torque per the toolholder manufacturer specifications. Confirm bore depth and diameter with appropriate gauging before running a production cycle.
