The Carmex Carbide Tiny Tool - Boring Bar is a precision solid carbide bar designed for tight-bore work and small-diameter turning. Built for reliability in demanding workshops, it helps you access confined spaces while delivering consistent, accurate results. This tool is ideal for engineers, machinists, and hobbyists who need a compact solution that doesn’t compromise on performance.

Designed primarily for boring but versatile enough for general turning, it comes in two TNX-grade coatings to match your material and cutting speed: BXC TiN-coated for reliable performance at lower speeds with stainless steels, and BMK with a sub‑micron, triple coating for excellent heat resistance and smooth cutting. Key specs include a 1.5 mm minimum diameter, 6 mm reach, and a left-hand nose with a 0.1 mm radius for precise, controlled cuts.

• Ultra-compact boring geometry: Access tight bores with a 1.5 mm minimum diameter and 6 mm reach, while maintaining stable cuts and tight tolerances. The left-hand orientation supports specific turning setups without changing tools.
• Two coating options tuned for performance: Choose BXC TiN-coated for dependable cutting in stainless steels at lower speeds (ISO P30–P50 / K25–K40) or BMK triple-coated for maximum heat resistance and smooth cutting across a wide material range (ISO K10–K20).
• Solid carbide durability and controlled finish: Built from hard, wear‑resistant carbide for long tool life, repeatable results, and reduced downtime during production runs or repairs.

This tiny boring bar helps you complete precise, small-diameter work more efficiently, with fewer tool changes and less setup time. Its rigid carbide construction and thoughtfully chosen coatings optimize performance on stainless steels and other challenging materials, delivering clean finishes, consistent dimensions, and reliable results across turning and boring applications.
