Carmex Carbide Tiny Tool - Boring Bar - MTR - BMK Grade - 6.1mm Minimum Diameter x 35mm Reach x R0.2

The Carmex Carbide Tiny Tool - Boring Bar is a precision solid carbide bar designed for tight internal features and reliable turning tasks. With a 6.1 mm minimum diameter, a 35 mm reach, and a nose radius of R0.2, it excels at accessing deep bores while delivering consistent, clean finishes.

This tool line is offered in two coating grades to match different materials and speeds. BXC is a PVD TiN-coated grade optimized for low cutting speeds and works well with a wide range of stainless steels (ISO P30-P50 / K25-K40). BMK is a sub-micron grade with an advanced PVD triple coating, delivering extremely high heat resistance for maximum performance and smooth cutting, making it a general purpose tool for all materials.

• Dual coating options for versatile performance: Choose BXC TiN-coated grade for stainless steels at lower speeds or BMK for high heat resistance and smooth cutting across a broad material range, giving you the right tool for the job.
• Long reach and precise bore geometry: 6.1 mm minimum diameter with a 35 mm reach lets you access tight, deep bores while maintaining stable, accurate cuts.
• R0.2 nose radius for smooth, accurate finishes: A fine nose radius promotes clean entry and consistent hole quality, reducing chatter and improving surface finish in boring and turning tasks.

Designed to deliver reliable, repeatable results, this tool reduces setup time and downtime while maintaining consistent performance across materials. It supports improved workflow, better surface finishes, and predictable results, making it a dependable choice for engineers, machinists, and hobbyists who require durable, precise boring and turning tools.
