Carmex Carbide Tiny Tool - Boring Bar - MTL - BMK Grade - 2.5mm Minimum Diameter x 15mm Reach x R0.1 (Left Hand)

The Carmex Carbide Tiny Tool is a compact, solid carbide boring bar designed for small-diameter holes and precision turning. With a 2.5 mm minimum diameter, a 15 mm reach, and a 0.1 mm nose radius, it delivers controlled, accurate cuts in tight spaces. This left-handed tool excels in boring and light turning across a range of materials, making it a versatile addition to any workshop or production floor.

Available in BMK and BXC coating options, these bars combine durability with smooth cutting performance. BMK offers sub-micron grade technology with a triple PVD coating for maximum heat resistance and reliable cuts, suitable for general-purpose use across all materials. BXC TiN-coated grade is optimized for low cutting speeds and works well with a wide range of stainless steels (ISO P30-P50 / K25-K40), helping extend tool life in demanding stainless applications.

• Compact size with long reach: 2.5 mm minimum diameter and 15 mm reach place cutting power where space is tight, enabling precise boring and finishing passes in small parts with minimal tool changes.
• BMK Grade with advanced PVD coating: Sub-micron carbide with a triple PVD coating provides excellent heat resistance and smooth cutting, delivering consistent performance across a broad range of materials.
• BXC TiN-coated option for stainless steel and low-speed cutting: TiN coating reduces wear and friction at lower speeds, making it ideal for stainless steels and challenging materials while maintaining steady chip control.

This tiny carbide boring bar is designed to improve workflow by delivering reliable, repeatable results in tight bores and small features. Its robust carbide core and high-performance coatings help extend tool life, minimize downtime, and produce consistent hole quality, making it a dependable choice for engineers, machinists, and hobbyists alike.
