The Carmex Carbide Tiny Tool - Boring Bar is a solid carbide micro-machining bar designed for precise bore work and general turning tasks. Its compact geometry lets you reach tight internal features with dependable stability, making it ideal for small-diameter projects and prototypes.

• Ultra-compact boring capability: Access tight internal features with a 2.5 mm minimum diameter and 10 mm reach, delivering stable cuts and accurate hole finishes in small or difficult-to-reach bores.
• Coating options for versatile performance: BXC TiN-coated grade is optimized for low cutting speeds on stainless steels (ISO P30-P50 / K25-K40), while BMK sub-micron grade with triple PVD coatings provides high heat resistance and smoother cutting across a broad range of materials.
• Rigid carbide construction with precise tip geometry: Solid carbide construction delivers consistent rigidity and wear resistance, and the R0 end geometry supports clean engagement in micro bores for reliable, repeatable results.

This tiny boring bar helps you complete micro-scale internal features with confidence, improving workflow by reducing tool changes and setup time. The combination of Coated carbide chemistry and a compact reach supports longer tool life, steadier cutting, and better surface finishes across stainless steels and more, making it a dependable choice for engineers, machinists, and hobbyists tackling small, demanding precision work.
