Carmex Carbide Tiny Tool is a compact solid carbide boring bar designed for precision in small bores and tight features, with a left-hand cutting geometry. It features a 6.1 mm minimum diameter, 35 mm reach, and a 0.2 mm nose radius to deliver clean, accurate cuts in confined spaces. While optimized for boring, it also handles general turning tasks, making it a versatile choice for engineers, machinists, and hobbyists working on tight-diameter components.

For material flexibility and performance, this tool line offers two PVD-coated grades. BXC is a TiN-coated grade optimized for low cutting speeds and a wide range of stainless steels (ISO P30-P50 / K25-K40). BMK is a sub-micron grade with an advanced triple PVD coating, delivering high heat resistance and smooth cutting (ISO K10-K20). These coatings provide dependable performance across a broad set of materials and applications.

• Ultra-compact boring bar geometry: 6.1 mm minimum diameter, 35 mm reach, and a 0.2 mm nose radius enable precise, repeatable cuts in tight bores and deep features with left-hand cutting orientation for specific sequences.
• Coated carbide options for versatility: Choose BXC TiN for stainless steels at lower speeds or BMK’s triple-coated, high-heat-resistant carbide for demanding materials, ensuring reliable performance across common production scenarios.
• Durable tool life for boring and turning: Solid carbide construction provides wear resistance and stable cutting action, delivering consistent surface finishes and reducing tool changes on both boring and general turning tasks.

Whether you’re producing tight-tolerance bores or performing routine turning, Carmex Tiny Tool delivers reliable, repeatable results across materials. The combination of compact geometry, durable carbide, and versatile coatings helps you maintain tight tolerances, achieve clean surface finishes, and keep workflow moving with fewer interruptions.
