Carmex Carbide Tiny Tool - Boring Bar - MTR - K20 Grade - 6.1mm Minimum Diameter x 22mm Reach x R0.05

The Carmex Carbide Tiny Tool - Boring Bar is a compact, solid carbide tool designed for tight internal boring and small-diameter turning. Made from K20 grade carbide, it delivers rigidity and durability for repeated accuracy. With a 6.1 mm minimum diameter, 22 mm reach, and an R0.05 corner radius, it enables clean, precise holes in hard-to-reach places.

As part of Carmex's line of solid carbide bars, this tool is built to perform in demanding shop environments. It offers coating options to optimize wear and finish: BXC TiN-coated grade for low-speed cutting and stainless steels (ISO P30-P50 / K25-K40); and BMK sub-micron grade with a triple PVD coating for exceptional heat resistance and smooth cutting across a broad material range.

• Compact size with deep reach: 6.1 mm minimum diameter and 22 mm reach let you access tight bores and reach deeper into parts while maintaining rigidity for clean, accurate cuts.
• Coating options for durability and smooth cutting: BXC TiN coating reduces friction and improves life at low cutting speeds, especially on stainless steels; BMK triple PVD coating offers excellent heat resistance and smooth cutting across many materials.
• Versatile for boring and general turning: Although optimized for boring, this solid carbide bar handles a range of turning tasks, delivering reliable, repeatable results across common materials.

This Tiny Tool helps you improve workflow and results by delivering precise holes with less tool swapping, smoother cutting, and longer tool life. Its compact 6.1 mm diameter, 22 mm reach, and R0.05 radius fit into restricted spaces, while the coating options maximize wear resistance and heat tolerance across stainless steels and other materials. Rely on Carmex for repeatable bore quality, reduced downtime, and dependable performance in both production environments and detailed projects.
