The Carmex Carbide Tiny Tool - Boring Bar is a compact solid carbide tool designed for ultraprecise small-diameter boring and versatile turning tasks. Built for engineers, fabricators, and hobbyists alike, it delivers dependable hole quality and smooth cutting in a compact form factor.

• Precision small-diameter design: 6.1 mm minimum diameter with a 40 mm reach and an R0.2 nose radius enables accurate hole placement in tight spaces and delivers clean, consistent surface finishes.
• Two coatings for versatile performance: BXC TiN coating provides reliable cutting at lower speeds and works well with stainless steels (ISO P30-P50 / K25-K40); BMK sub-micron grade with triple PVD coating offers high heat resistance for demanding materials and smooth cutting life.
• Solid carbide durability: A rigid carbide body delivers long tool life and wear resistance, reducing tool changes and maintaining stable performance through multiple passes.

This tiny boring bar is engineered to improve workflow by delivering stable cutting in tight pockets, preserving dimensional accuracy, and providing reliable results across a range of materials. With its robust construction and grade options, you can tailor the tool to your material and speed needs, helping you finish projects faster with consistent outcomes.
