Description
Carmex Carbide Tiny Tool – Boring Bar is a compact, solid carbide solution engineered for precision boring while delivering the versatility to handle general turning tasks. With a 6.1 mm minimum diameter, 15 mm reach, and a left-hand orientation featuring a 0.2 mm corner radius, this tool is designed to fit tight bores and deliver consistent, clean finishes.
Designed to cover a range of materials, it leverages two advanced coating options to match your cutting needs. The BXC grade uses a PVD TiN coating for reliable performance at low cutting speeds and pairs well with a wide range of stainless steels (ISO P30-P50 / K25-K40). The BMK grade features a sub-micron structure with an advanced PVD triple coating, delivering exceptionally high heat resistance for maximum performance and smooth cutting across materials, making it a true general-purpose option.
- Designed for boring with turning versatility: This solid carbide bar is optimized for boring operations but can also handle general turning, reducing tool changes and expanding your single-tool capability.
- Two coating options for flexible material compatibility: Choose BXC TiN for low-speed stainless steel work or BMK’s triple-coated, high-heat-resistant performance for broader material use and smoother cuts.
- Precise, compact geometry for reliable bore quality: With a 6.1 mm minimum diameter, 15 mm reach, and a left-hand R0.2 corner radius, it delivers consistent bore geometry in tight spaces.
By selecting this tool, you gain a dependable boring bar that maintains steady cutting action, extends tool life across materials, and supports efficient workflows in both boring and turning operations. Its dual coating options and compact geometry help you achieve repeatable results with less downtime and setup friction.
