Description

The Carmex Carbide Tiny Tool is a compact solid carbide bar designed for full-radius grooving in turning applications. Its precise geometry delivers clean, repeatable radii on small-diameter workpieces, helping you achieve accurate grooves with fewer finishing passes. It’s also a capable general turning tool when you need a reliable cut on a variety of materials.

Available with two coating options within the BMK family to suit different materials and speeds: BXC TiN coated grade optimized for low cutting speeds and excellent performance on stainless steels (ISO P30-P50 / K25-K40), and BMK sub-micron grade with advanced PVD triple coating for maximum heat resistance and smooth cutting across a broad material range. With a 7.1 mm minimum diameter, 1.5 mm groove width, 22 mm reach, and a left-hand configuration, this tool is ready for tight pockets and challenging grooving tasks.

  • Full-radius grooving precision: Delivers consistent radii with stable cut quality, reducing finishing passes and improving groove seating on small-diameter parts.
  • Two coating grades for versatile performance: BXC TiN coating provides low-speed efficiency on stainless steels, while BMK triple-coated sub-micron grade offers superior heat resistance and smooth cutting across a wide material range.
  • Compact reach and left-hand geometry: 22 mm reach and left-hand setup maximize accessibility in tight pockets, enabling reliable grooving without repositioning the workpiece.

This tool helps you achieve consistent groove geometry and reliable results in challenging small-diameter parts, while minimizing downtime and setup changes. The rugged carbide construction, combined with optimized coatings, delivers dependable performance across stainless steel and other materials, enabling smoother cuts, cleaner grooves, and faster turnaround on turning operations.
