Carmex Carbide Tiny Tool - Boring Bar - MTL - BMK Grade - 6.1mm Minimum Diameter x 22mm Reach x R0.2 (Left Hand)

The Carmex Carbide Tiny Tool is a compact, solid carbide boring bar engineered for precision boring and versatile enough for general turning. It features a 6.1 mm minimum diameter, 22 mm reach, and a left-hand R0.2 corner radius to access tight bore conditions. Available in two high-performance grades—BXC and BMK—each using advanced PVD coatings to optimize cutting performance across materials and speeds: BXC TiN-coated for low-speed cutting in stainless steels (ISO P30-P50 / K25-K40), and BMK with a sub-micron grade and triple PVD coating for maximum heat resistance and smooth cutting across all materials.

• Coatings tailored for material and speed: BMK provides maximum heat resistance and smooth cutting across materials, while BXC TiN-coated grade is optimized for lower cutting speeds and stainless steels, helping you maintain consistent results across a range of alloys.
• Compact boring geometry for tight access: With a 6.1 mm minimum diameter, 22 mm reach, and a left-hand R0.2 corner, it reaches narrow bores and produces clean, controlled cuts with stable chip flow.
• Rigid carbide construction for long tool life: Solid carbide core delivers rigidity and wear resistance, reducing tool changes and delivering reliable performance in demanding turning and boring applications.

This tool delivers dependable, versatile performance for small-diameter bore work and general turning. The dual coating options let you tailor performance to speed and material—BMK for high-heat, wide-material use, and BXC for stainless steels at lower speeds—while the precise geometry and carbide rigidity help achieve consistent finishes, tight tolerances, and fewer interruptions in your machining workflow.
