The Carmex Carbide Tiny Tool - Boring Bar - MTR - BXC Grade - 5.1mm Minimum Diameter x 15mm Reach x R0.2 is a line of solid carbide bars designed primarily for boring applications, with the versatility to handle general turning jobs. Its compact geometry and precise dimensions (5.1 mm minimum diameter, 15 mm reach, and a 0.2 mm nose radius) help you access tight bores and challenging features with dependable cutting performance.

• Small-diameter, long-reach geometry: With a 5.1 mm minimum diameter, 15 mm reach and an R0.2 nose radius, this tool is optimized for precise boring and turning in tight spaces.
• Two coated grades for versatility: Choose BXC TiN-coated grade for low cutting speeds and stainless steels (ISO P30–P50 / K25–K40), or BMK sub-micron grade with a triple PVD coating (ISO K10–K20) for high heat resistance and smooth cutting across materials.
• Durable carbide with smooth cutting: Solid carbide construction paired with advanced coatings delivers reliable cutting action, longer tool life, and consistent finishes across a range of applications.

Designed for reliable performance in both boring and general turning tasks, this tool helps you maintain steady workflow, reduce tool changes, and achieve consistent results across stainless steels and other materials. Its dual-grade coating options provide the adaptability you need for different speeds and materials, making it a practical, long-lasting choice for engineers, machinists, and hobbyists alike.
