Carmex Carbide Tiny Tool – Boring Bar is a compact solid carbide bar designed for precise boring and versatile turning tasks. With a 3.1 mm minimum diameter, 15 mm reach, and a left-hand orientation, this tool excels in tight-part machining where consistency and finish matter. It’s the right choice for engineers, machinists, and hobbyists who need reliable performance in small-diameter bores and delicate turning operations.

• Optimized boring and turning geometry: Delivers precise hole sizes and reliable cutting in tight-part work thanks to a compact 3.1 mm minimum diameter, 15 mm reach, and a refined edge design that supports clean finishes.
• Coated carbide grades for wide material compatibility: Choose BXC TiN coating for low cutting speeds on stainless steels, or BMK’s sub-micron grade with triple PVD coating for excellent heat resistance and smoother cuts across a broad range of materials.
• Left-hand configuration with a precise R0.05 edge: The left-hand orientation and small corner radius provide stable cuts, reduce chatter, and help achieve consistent, high-quality finishes in demanding boring and turning tasks.

This carbide boring bar is built to deliver repeatable results in everyday shop environments. The dual coating options extend life and performance across materials and speeds, while the compact form fits into confined setups without sacrificing rigidity or finish quality. Ideal for small-diameter bores and general turning, it supports efficient workflows and confident decision-making for professionals and hobbyists alike.
