The Carmex Carbide Tiny Tool is a compact, solid carbide boring bar in MTL K20 grade, engineered for precise small-diameter boring and general turning. With a 3.1 mm minimum diameter, a 10 mm reach, and a left-hand R0.1 nose, it reaches tight bores and narrow cavities while delivering clean, accurate cuts. Although designed primarily for boring, it handles general turning tasks as well, making it a versatile choice for production runs and small-scale projects.

• Compact size for tight bores: The 3.1 mm minimum diameter and 10 mm reach let you access confined spaces and deep features with consistent alignment and finish.
• Two coating options for versatile performance: BXC is a PVD TiN coating optimized for low cutting speeds and stainless steels (ISO P30–P50 / K25–K40); BMK is a sub-micron grade with a triple PVD coating for exceptional heat resistance and smooth cutting (ISO K10–K20).
• Left-handed geometry with a precise R0.1 nose: This orientation and small nose radius provide controlled cutting and smoother bore finishing, helping to reduce chatter and improve surface quality.

With its compact design, dual coating options, and purposeful geometry, the Carmex Tiny Tool delivers reliable, repeatable results across boring and turning tasks. Expect longer tool life, steadier cuts, and quicker setup in real-world machining, helping you boost productivity while maintaining consistent finishes on stainless steels and other materials alike.
