Carmex Carbide Tiny Tool - Boring Bar - MTR - K20 Grade - 4.1mm Minimum Diameter x 15mm Reach x R0.1

Carmex Carbide Tiny Tool is a compact, solid carbide boring bar designed for precision internal turning in tight spaces. It features a 4.1 mm minimum bore, a 15 mm reach, and a 0.1 mm nose radius for clean, accurate holes across a range of materials. This tool family includes two coating grades—BXC TiN-coated for low-speed stainless cutting and BMK for high-heat performance—to cover a broad set of applications from general turning to demanding boring work.

• Compact micro-bore design: 4.1 mm minimum diameter with a 15 mm reach and a 0.1 mm nose radius lets you bore tight holes in confined bores and pockets without tool changes, improving layout efficiency and accuracy.
• Coated versatility for stainless and general materials: BXC TiN coating reduces friction and wear at lower cutting speeds, well-suited to stainless steels (ISO P30-P50 / K25-K40) for longer tool life and smoother finishes.
• BMK high-heat performance and smooth cutting: BMK sub-micron grade with triple PVD coating delivers exceptional heat resistance and stable cutting, making it a reliable choice for demanding materials and longer runs.

By choosing the Carmex Tiny Tool, you gain predictable, repeatable results in tight-tolerance bores, reduced downtime from longer tool life, and a straightforward setup that keeps you productive in cramped machining zones. The carbide construction provides stiffness and durability, while the coating options let you tailor performance to the job at hand—whether you’re dialing in stainless workpieces or pushing through tougher materials. This tiny boring bar helps you complete precision boring and general turning tasks with confidence and efficiency.
