Carmex Carbide Tiny Tool — Boring Bar for small-diameter machining. This solid carbide bar is engineered primarily for precise boring but also handles general turning tasks, making it a versatile choice for engineers, machinists, and hobbyists who need reliable performance in tight spaces. It features a 6.1 mm minimum diameter, a 40 mm reach, and a compact R0.2 nose, designed to produce clean holes with minimal chatter.

• Precision carbide design for tight bores: Built for stability in small-diameter work, the 6.1 mm minimum diameter with 40 mm reach and a precise R0.2 nose deliver accurate, smooth cuts in confined bores and pockets.
• Coatings engineered for durability and performance: BMK-grade offers sub-micron carbide with advanced PVD triple coating for excellent heat resistance and smooth cutting; BXC-grade provides a TiN coating optimized for low cutting speeds, expanding compatibility with stainless steels.
• Reliable results across materials: Designed for long tool life and consistent performance in a wide range of materials, reducing downtime and helping you maintain steady workflow in demanding operations.

This tiny, rugged boring bar is built to improve your machining outcomes: the carbide core delivers rigidity for true hole geometry, while the specialized coatings minimize wear and heat buildup during extended cuts. With proper speeds and feeds, you can expect smooth entry, stable cutting, and reliable finishes across stainless steels and other metals, making the Carmex Tiny Tool a practical, durable addition to your shop lineup.
