The Carmex Carbide Tiny Tool - Boring Bar is a compact, solid carbide cutting tool designed for tight spaces and precise boring, with the versatility to handle general turning tasks as well. It’s ideal for engineers, machinists, hobbyists, and buyers who need reliable performance in small-diameter holes, edge-finishing, or delicate turn operations. Built for durability, it delivers accurate geometry and consistent results where space is at a premium.

• Ultra-compact boring bar geometry: Access tight bores with a 4.1 mm minimum diameter, a 10 mm reach, and an R0.2 corner radius, enabling precise, stable cuts in confined work areas.
• Two coating grades for versatile machining: Choose BXC TiN for low-speed stainless steel work (ISO P30-P50 / K25-K40) or BMK’s sub-micron, triple-coated design for high heat resistance and smooth cutting across a broader material range (ISO K10-K20).
• Rugged carbide construction for durability: Solid carbide core with wear-resistant coatings delivers consistent performance, longer tool life, and repeatable finishes across demanding boring and turning applications.

This tiny tool line is engineered to simplify setups, reduce tool changes, and maintain precise finishes in small-diameter bores. With its robust carbide base and specialized coatings, it provides reliable performance across materials and cutting speeds, helping you improve throughput and achieve predictable results in both production and repair environments.
