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

The Carmex Carbide Tiny Tool is a compact, solid carbide boring bar designed for precision internal boring and small-diameter turning. Built for tight bores and demanding stainless steels, it delivers dependable, stable performance in constrained spaces. This left-handed bar features a 3.1 mm minimum diameter, 10 mm reach, and a precise R0.1 nose radius to help you maintain tight tolerances without rearranging your setup.

The tool line is available in two advanced coating options to suit different job conditions: BXC (PVD TiN) coated grade optimized for low cutting speeds and stainless steels (ISO P30–P50 / K25–K40), and BMK (sub-micron grade with a triple PVD coating) that delivers exceptional heat resistance and smooth cutting across a wide range of materials. These coatings enhance edge life, reduce wear, and help you achieve consistent finishes in both lightweight and demanding applications.

• BXC TiN-coated for stainless steel efficiency: Reduces friction and heat at low cutting speeds, helping maintain precise hole diameters and extending tool life when machining stainless steels (ISO P30–P50 / K25–K40).
• BMK triple-coated high-heat performance: Sub-micron grade with advanced PVD triple coating offers superior heat resistance and smooth cutting, enabling reliable results across many materials.
• Compact geometry for tight bores: 3.1 mm minimum diameter, 10 mm reach, and left-hand R0.1 nose provide access to confined spaces and stable cutting in small-diameter boring and general turning.

Designed to streamline internal turning and boring workflows, the Carmex Tiny Tool delivers dependable, repeatable results in a compact, easy-to-integrate package. Its carbide construction and proven coatings resist wear, support longer tool life, and help you finish projects with consistent accuracy—whether you’re preparing high-precision parts or running high-volume work in a busy shop.
