The Carmex Carbide Tiny Tool Boring Bar is a compact, solid carbide tool designed for precise boring and versatile turning on small-diameter work. With a 5.1 mm minimum diameter, 22 mm reach, and a 0.2 mm nose radius, it provides reliable access to tight bores and pockets while delivering consistent results.

Two high-performance grades expand its range for different materials and cutting speeds. BXC is a PVD TiN coated grade optimized 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, offering extremely high heat resistance for maximum performance and smooth cutting, making it a solid general-purpose option for all materials.

• Ultra-Compact Boring Bar for Tight Bores: Access confined cavities with a 5.1 mm diameter, 22 mm reach, and a precise 0.2 mm nose radius for dependable starts and finishes.
• Grade Options for Material Versatility: Choose BXC for stainless steels at low speeds or BMK for broad material compatibility and enhanced heat tolerance.
• Coating-Driven Performance and Durability: TiN and triple-PVD coatings paired with carbide provide smoother cuts, better edge retention, and longer tool life in demanding applications.

This tool is engineered to improve workflow by delivering consistent, reliable performance across common boring and turning tasks. Its compact form and durable coatings help reduce tool changes, improve finish quality, and maintain tight tolerances in challenging small-diameter work.
