Description

The Carmex Carbide Tiny Tool is a partial-profile threading bar engineered for precision threading in tight spaces. It’s designed for 55° thread profiles, making it a versatile choice for engineers, tradespeople, buyers, hobbyists, and non-technical users who need reliable threads in small bores or hard‑to‑reach areas.

This tool line offers two advanced PVD coating grades to suit different jobs: BMK for extreme heat resistance and smooth cutting, and BXC TiN for dependable performance at lower cutting speeds. Together they deliver durable, consistent results across a wide range of materials, including stainless steels (ISO P30-P50 / K25-K40) and beyond, making it a dependable, general‑purpose solution.

  • 55° partial‑threading design: Enables precise, partial threads in confined spaces, reducing setup time and enabling accurate results in small bores.
  • Coatings for versatile performance: BMK sub‑micron grade with triple PVD coating delivers high heat resistance and smooth cutting; BXC TiN coating provides reliable performance at low cutting speeds, extending tool life across stainless steels.
  • Compact size with practical reach: 3.2 mm minimum diameter and 15 mm reach (with bore compatibility down to 1.2 mm) lets you access tight areas while delivering consistent threading quality.

This combination of targeted geometry, dual high‑performance coatings, and a compact form factor helps you complete threading tasks efficiently, with reliable results across materials and in challenging workspaces. The tool’s design supports steady cutting action, longer life under demanding conditions, and confidence‑in‑use across professional shops and DIY setups alike.
