Description
The Carmex Carbide Tiny Tool is a compact solid carbide boring bar designed for tight bore work and short reach applications. It excels at precision boring and general turning, making it a practical choice for engineers, machinists, and hobbyists who need reliable performance in small spaces.
Machined from MTR K20 grade carbide, this tool features a 6.1 mm minimum diameter, a 15 mm reach, and a 0.2 mm nose radius to deliver controlled, stable cuts in restricted areas. It’s offered with coating options designed to optimize performance across materials and speeds, including BXC TiN for low cutting speeds and stainless steels, and BMK with advanced PVD triple coating for demanding uses.
- Compact, precise boring geometry: Fits tight bores and short-reach jobs with a 6.1 mm minimum diameter, 15 mm reach, and a 0.2 mm nose radius for accurate, stable cuts.
- Coating and grade versatility for different materials: Choose BXC TiN for stainless steels at low speeds, or BMK’s triple-coated structure for higher heat resistance and smooth cutting across a wider material range.
- Durable carbide with reliable cutting performance: MTR K20-grade carbide paired with advanced coatings delivers wear resistance and consistent results across materials, helping you maintain throughput and reduce tool changes.
This tiny tool supports efficient workflows by delivering predictable bore quality, extended tool life, and the flexibility to tackle stainless steels and a broad spectrum of materials in demanding applications—all from a compact, easy-to-use boring bar.
