Carmex Carbide Tiny Tool - Boring Bar - MTL - BMK Grade - 3.1mm Minimum Diameter x 10mm Reach x R0.1 (Left Hand)

Carmex Carbide Tiny Tool is a compact line of solid carbide boring bars designed for precision boring and versatile turning tasks. With a 3.1 mm minimum diameter, 10 mm reach, and a left-hand configuration, these bars are built to perform in tight spaces and on small-diameter workpieces while delivering repeatable, clean cuts.

This tool family features two advanced PVD-coated grades to match your material and speed needs. BXC is a TiN-coated grade engineered 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 (ISO K10-K20) that delivers extremely high heat resistance and smooth cutting, making it a solid general-purpose choice for materials across the board.

• Versatile coating options for stainless steels and general materials: BXC with TiN coating supports low-speed cutting on stainless steels, while BMK’s triple PVD coating provides high heat resistance and smooth cutting for broad material compatibility.
• Compact size designed for tight bores: 3.1 mm minimum diameter and 10 mm reach in a left-hand design let you access confined features and maintain precise alignment for consistent results.
• Durable carbide construction for reliable life: Solid carbide construction delivers long tool life and stable performance in boring and turning, even under demanding conditions and higher feeds.

Whether you’re machining tight internal bores, finishing internal features, or performing general turning, Carmex Tiny Tool helps you achieve consistent tolerances, cleaner finishes, and improved workflow efficiency. The combination of robust carbide, optimized coatings, and a compact geometry is designed to reduce downtime and deliver reliable performance across a wide range of materials.
