Description

Carmex Carbide Tiny Tool is a compact solid carbide boring bar designed for precise small-diameter work and versatile turning tasks. Built for reliable performance in tight spaces, it's ideal for machine shops, engineers, and hobbyists who need consistent bore finishes with minimal setup.

Designed for the TNX-grade lineup, this bar features a 7.1 mm minimum diameter, 22 mm reach, and a left-hand nose with an R0.2 radius. It offers two coating options to match your material mix: BXC, a PVD TiN-coated grade optimized for low cutting speeds and stainless steels; and BMK, a sub-micron grade with a triple PVD coating that delivers high heat resistance and smooth cutting across a broad range of materials.

  • Two TNX-grade coating options for versatile material compatibility: BXC is a PVD TiN-coated grade optimized for low cutting speeds and stainless steels (ISO P30-P50 / K25-K40), helping extend tool life and deliver stable finishes; BMK is a sub-micron grade with an advanced PVD triple coating (ISO K10-K20) for high heat resistance and smooth cutting across materials.
  • Compact geometry for precise, deep bore work: 7.1 mm minimum diameter, 22 mm reach, and left-hand R0.2 nose geometry enable access to tight pockets and shallow bores while maintaining rigidity and consistent tool engagement.
  • Durable carbide construction with coated reliability: Solid carbide core combined with advanced coatings delivers wear resistance, edge stability, and predictable performance across a range of materials, reducing downtime and tool changes.

With these features, the Carmex Tiny Tool supports repeatable bore finishes in tight spaces, improves setup efficiency, and delivers reliable performance across stainless steels and other materials. Its compact size, dual coating options, and durable carbide construction make it a dependable choice for precision boring and general turning tasks alike.
