Carmex Carbide Tiny Tool - Boring Bar - MTL - BMK Grade - 2.1mm Minimum Diameter x 5mm Reach x R0.05 (Left Hand)

The Carmex Carbide Tiny Tool is a compact, solid carbide boring bar designed for small-diameter bores and precision turning. With a minimum bore diameter of 2.1 mm, a 5 mm reach, and a left-hand R0.05 nose, it delivers repeatable results in tight workpieces. This tool is ideal for engineers, machinists, and hobbyists who need reliable performance in restricted spaces.

Designed primarily for boring but also suitable for general turning, this tool supports two coating grades to match material and cutting conditions: BXC is a PVD TiN-coated grade optimized for low cutting speeds and works well with a wide range of stainless steels (ISO P30-P50 / K25-K40); BMK is a sub-micron grade with an advanced PVD triple coating, offering extremely high heat resistance for maximum performance and smooth cutting — a versatile, general-purpose option for all materials.

• Ultra-compact bore capability: 2.1 mm minimum diameter, 5 mm reach, and left-hand orientation enable precise entry and access to tight pockets and features.
• Versatile coating options for broad material support: BXC TiN coating excels at low-speed stainless steel work, while BMK’s sub-micron, triple-coated design delivers high heat resistance and smooth cutting across a wide material range.
• Durable carbide construction for reliable performance: Solid carbide bars provide wear resistance and long tool life, reducing downtime and helping maintain consistent bore quality across jobs.

With the Carmex Tiny Tool, you benefit from precise, repeatable bores in tight spaces, quicker setup, and fewer tool changes. Its coated carbide design and left-hand geometry give you confident performance on challenging parts, whether in production or hobby machining.
