The Carmex Carbide Tiny Tool is a compact, solid carbide boring bar engineered for precise internal boring and light turning tasks. With a 3.1 mm minimum diameter, a 15 mm reach, and a left-handed geometry with an R0.2 corner radius, it’s the ideal choice for small-diameter components where accuracy matters. Designed to handle a range of materials, including stainless steels, this tool helps you achieve clean finishes and consistent performance in tight spaces.

This line of carbide bars offers coating options to match your cutting needs. BXC TiN-coated variants deliver reliable performance at lower speeds on stainless steels (ISO P30-P50 / K25-K40), while BMK sub-micron variants with advanced PVD triple coating provide excellent heat resistance and smooth cutting across a broad range of materials.

• Ultra-compact boring bar for tight bores: Dimensions of 3.1 mm minimum diameter, 15 mm reach, and R0.2 corner radius enable precise, clean cuts in small bores and hard-to-reach features.
• Coating options for optimized cutting: BXC TiN for low-speed stainless-steel work or BMK triple-coated variants for high heat resistance, helping reduce wear and extend tool life across materials.
• Left-hand geometry for stable cutting: Left-handed orientation supports predictable toolpaths and smooth chip flow in boring and light turning, reducing setup time and chatter.

The Carmex Tiny Tool helps you complete small-diameter bores with confidence, delivering consistent finishes, longer tool life, and reduced downtime in busy shops. Its solid carbide construction and specialized coatings resist wear, while the compact form minimizes tool changes and setup, enabling efficient production and reliable results across stainless steels and other materials.
