The Carmex Carbide Tiny Tool is a compact, solid carbide boring bar designed for precise boring and versatile enough for general turning. With a 6.1 mm minimum diameter, 35 mm reach, and R0.2 left-hand geometry, it excels in tight bores and finishes with clean, consistent cuts. This tool is offered in two coated grades to tackle a wide range of materials: BXC TiN-coated for low cutting speeds and stainless steels (ISO P30-P50 / K25-K40), and BMK sub-micron grade with advanced PVD triple coating for extremely high heat resistance and smooth cutting across all materials.

• Two coating-grade options for versatile materials: BXC TiN-coated grade supports low cutting speeds and performs well with stainless steels (ISO P30-P50 / K25-K40). BMK sub-micron grade with an advanced PVD triple coating provides extremely high heat resistance for maximum performance and smooth cutting across a general material range.
• Compact geometry for tight bores: 6.1 mm minimum diameter, 35 mm reach, and R0.2 left-hand corner radius give access to confined features and enable clean entry and exit in boring operations.
• Reliable performance under demanding conditions: Carbide with PVD coatings delivers smooth cutting operation and consistent results, helping you complete jobs on stainless steels and other materials with confidence.

Whether you're building prototypes, performing maintenance, or running production work, this tiny boring bar offers dependable performance in a compact form. The dual coating options let you optimize for speed, heat, and material type, while the precise geometry and robust carbide construction help you maintain tolerances, finish quality, and workflow efficiency across a wide range of materials.
