Carmex Carbide Tiny Tool is a compact threading bar designed for precision in tight spaces. It supports MIL 55° thread profiles and is configured for left-hand threading, with a practical reach that helps you access deep or narrow bores without repositioning. Built from durable K20-grade carbide, this tool delivers reliable performance in a variety of stainless steels and common engineering materials.
- 55° partial-profile threading compatibility: Optimized for MIL 55° threads in confined areas, enabling accurate starts and consistent pitch on challenging workpieces and stainless steels.
- Coating options for versatility: Choose between BXC TiN-coated grade for low cutting speeds on stainless steels and BMK sub-micron grade with triple PVD coating for high heat resistance and smooth cutting, expanding capability across materials.
- Small-bore performance with long reach: Designed for minimum bore diameters down to 1.2 mm (0.05 in) with a 22 mm reach, plus left-hand orientation to access tight features while maintaining stable, reliable cuts.
Together, these features deliver precise, repeatable threading results in tight spaces, with durable carbide and coatings that support longer tool life and steadier performance. The Carmex Tiny Tool helps streamline setup, minimize rework, and improve overall efficiency when working with small bores and stainless steels or general-purpose materials.
