Carmex Carbide Tiny Tool - Boring Bar - MTL - BXC Grade - 4.1mm Minimum Diameter x 10mm Reach x R0.1 (Left Hand)

Carmex Carbide Tiny Tool - Boring Bar is a compact, solid carbide bar designed for precise boring and light turning in tight spaces. With a 4.1 mm minimum diameter, 10 mm reach, and a left-hand R0.1 nose, it delivers reliable bore geometry on small-diameter workpieces and short-length components.

This product line covers two coated grades to suit different materials and speeds: BXC is a PVD TiN coated grade for low cutting speeds, working well with a wide range of stainless steels (ISO P30-P50 / K25-K40); BMK is a sub-micron grade with advanced PVD triple coating, delivering extremely high heat resistance and smooth cutting for general-purpose use across materials.

• Tiny-diameter, high-precision boring capability: 4.1 mm minimum diameter, 10 mm reach, and a left-hand R0.1 nose enable accurate bore geometry in tight spaces and short-length components, reducing the need for secondary operations.
• TiN-coated BXC grade for low-speed machining: The PVD TiN coating minimizes friction and wear at low cutting speeds, helping extend tool life when machining stainless steels (ISO P30-P50 / K25-K40).
• BMK grade for high-heat reliability and versatility: Sub-micron BMK with triple PVD coating provides exceptional heat resistance and smooth cutting, suitable for a wide range of materials and demanding applications.

Designed to improve efficiency and consistency, the Carmex Tiny Tool supports tighter tolerances, cleaner finishes, and fewer tool changes in real-world production and workshop settings. The solid carbide construction delivers stiffness and durability for reliable performance, while the coated grades let you tailor machining to your material and speed conditions. Whether you’re focused on small-diameter bores or broad turning tasks, this tool provides dependable results and a straightforward setup that helps you complete jobs faster with confidence.
