Carmex Carbide Tiny Tool - Boring Bar - MTL - BMK Grade - 8.1mm Minimum Diameter x 35mm Reach x R0.2 (Left Hand)

The Carmex Carbide Tiny Tool is a compact carbide boring bar engineered for precise boring and general turning in tight spaces. Its 8.1 mm minimum diameter, 35 mm reach, and R0.2 corner radius in a left-hand configuration provide stable, accurate holes in small components while simplifying setup and repeatable results.

Two coated grades offer flexible performance across materials and cutting conditions. The BXC PVD TiN coating supports reliable cutting at low speeds, delivering consistent results with stainless steels (ISO P30–P50 / K25–K40). The BMK sub-micron grade features an advanced PVD triple coating for exceptional heat resistance and smooth cutting, making it a strong general-purpose choice for a wide range of materials.

• Compact boring capability for tight bores: The 8.1 mm minimum diameter with 35 mm reach and an R0.2 corner allow access to confined cavities while maintaining hole accuracy, reducing the number of passes and setup time.
• Two high-performance coating grades for versatility: Choose BXC TiN for low-speed stainless steel work or BMK with triple PVD coating for improved wear resistance and heat tolerance across many materials, helping you extend tool life between changes.
• Left-hand geometry for predictable chip flow and finishes: The left-hand cutting design supports consistent chip control and reliable surface finishes in turning and boring operations.

With its solid carbide construction and optimized coatings, this tiny tool delivers dependable, repeatable results in tight bores and small-part turning. It helps streamline setups, reduces downtime from tool changes, and delivers consistent hole quality and finish across common materials, making it a reliable choice for engineers, machinists, and hobbyists working on precise, compact components.
