Carmex Carbide Tiny Tool - Boring Bar - MTR - TNX Grade - 2.1mm Minimum Diameter x 5mm Reach x R0.15

The Carmex Carbide Tiny Tool Boring Bar is a compact, high-precision solid carbide cutting tool designed for boring and fine-turning tasks in small-diameter bores. With a minimum diameter of 2.1 mm, a reach of 5 mm, and an R0.15 nose radius, it delivers clean finishes and consistent bore geometry in tight spaces.

Built for versatility, this tool uses TNX-grade coatings and is available in two coating options tailored for different materials and speeds: BXC TiN-coated for low cutting speeds and stainless steels, and BMK with an advanced PVD triple coating for high heat resistance and smooth cutting across a wide material range. This combination makes the tiny boring bar suitable for general-purpose turning as well as demanding boring operations.

• R0.15 nose radius for precision finishes: The tiny tip radius enables clean bore surfaces and tight tolerances, reducing extra finishing passes and improving hole accuracy.
• Coating options for versatility and durability: Choose BXC TiN-coated for efficient cutting at lower speeds with stainless steels, or BMK’s triple PVD coating for exceptional heat resistance and smooth cutting across a broad range of materials.
• Compact, rigid carbide body with 2.1 mm min diameter and 5 mm reach: Access tight bores and reach deeper into parts while maintaining cutting rigidity and stable engagement.

With precise geometry, robust carbide construction, and coating versatility, this tiny boring bar helps you achieve consistent hole quality, reduce downtime, and extend tool life across a wide range of materials and applications. It’s a dependable choice for engineers, machinists, and hobbyists who value reliable performance in small-diameter boring and general turning tasks.
