The Carmex Carbide Tiny Tool is a compact solid carbide boring bar designed for small-diameter bores and tight workspaces. Although designed primarily for boring applications, these bars can also handle general turning. With a 6.1 mm minimum diameter, 15 mm reach, and a nose radius of R0.1, it delivers precise bore geometry in confined parts.

Available in coated grades, the line includes BXC TiN-coated options for low cutting speeds on stainless steels, and BMK sub-micron grade with advanced PVD triple coating for high heat resistance and smooth cutting across materials.

• Small-diameter, long-reach geometry: Access tight bores and restricted-clearance areas with a 6.1 mm minimum diameter and 15 mm reach, enabling precise finishes without repositioning.
• TiN-coated BXC grade for stainless steels: PVD TiN coating reduces wear and friction at low cutting speeds, delivering longer tool life and steadier cuts on stainless steels (ISO P30-P50 / K25-K40).
• BMK grade with triple PVD coating for all-material versatility: Sub-micron carbide with advanced triple coating provides exceptional heat resistance and smooth cutting, supporting reliable performance across a broad range of materials.

This tiny, robust boring bar helps you streamline setups, reduce tool changes, and achieve consistent bore finishes and turning results. The combination of precise geometry, durable carbide substrate, and purpose-built coatings translates into longer tool life, lower downtime, and dependable performance in challenging parts and confined spaces.
