The Carmex Carbide Tiny Tool is a precision micro boring bar crafted from solid carbide. With a 0.5 mm minimum diameter and a 2 mm reach, it fits into tight bores and restricted spaces while delivering dependable cutting performance. The left‑hand geometry and a tiny R0.05 corner radius help produce clean entry and exit with minimal burrs in confined features.

This tool is part of a versatile line designed for boring, but it also handles general turning jobs. It offers two coating options to match your material and speed goals: the BXC Grade with PVD TiN coating optimized for low cutting speeds on stainless steels (ISO P30–P50 / K25–K40), and the BMK Grade with sub‑micron precision and a triple PVD coating for exceptional heat resistance and smooth cutting across many materials.

• Ultra-small micro-boring capability: The 0.5 mm minimum diameter and 2 mm reach enable precision boring and tight-pocket turning in small-diameter workpieces, with left-hand geometry for controlled cutting in confined spaces.
• Coating options for versatile material compatibility: BXC TiN coating supports low-speed stainless steel work, while BMK’s sub‑micron, triple PVD coating delivers high heat resistance and smooth cutting for demanding materials.
• Left-hand geometry with tight corner radius: R0.05 corner radius and left-hand cutting orientation reduce tool deflection and burrs, delivering cleaner finishes in finishing passes and repeatable results.

Designed for engineers, machinists, and hobbyists alike, this tiny tool helps you complete micro-boring tasks with confidence. It supports reliable, consistent results across a range of materials, minimizes downtime through longer tool life, and helps maintain tight tolerances and smooth surface finishes in space-limited setups.
