Description

The Carmex Carbide Tiny Tool is a compact, TNX-grade boring bar built from solid carbide for precise boring and fine turning. With a 7.1 mm minimum diameter, 30 mm reach, and a left-hand R0.2 tip, it delivers stable, accurate holes in tight spaces—perfect for engineers, machinists, and hobbyists working on small-diameter projects.

As part of a versatile tool line, this bar supports two coating options to suit different materials and speeds: BXC, a PVD TiN-coated grade optimized for low cutting speeds and stainless steel (ISO P30-P50 / K25-K40); and BMK, a sub-micron grade with a triple PVD coating that delivers high heat resistance and smooth cutting across a wide range of materials.

  • Compact bore tool for precise holes: 7.1 mm minimum diameter, 30 mm reach, and a left-hand R0.2 corner radius provide accurate hole sizes and clean entry in tight spaces.
  • Coating options for versatility and performance: Choose BXC TiN for low-speed stainless steel work, or BMK’s sub-micron, triple-coated construction for high heat tolerance and smooth cutting across many materials.
  • Durable carbide construction for reliable life: Solid carbide construction delivers consistent results and long tool life in demanding boring and turning tasks.

This tiny boring bar helps you complete precise, repeatable work with fewer tool changes, improved finish quality, and dependable performance across materials. The TNX-grade design, left-hand geometry, and targeted coatings work together to enhance control, reduce downtime, and boost overall machining efficiency.
