The Carmex Carbide Tiny Tool is a compact threading cutter designed for small-diameter work. Built around an ACME trapezoidal thread form, it delivers precise, repeatable thread profiles on miniature parts where standard tools struggle.
Crafted from premium K20-grade carbide, this tool combines toughness and wear resistance with a compact footprint: a 12.5 mm minimum diameter and a 35 mm reach. It supports left-hand threading and is compatible with a wide range of machines and systems, making it a versatile choice for shops and labs.
- ACME Trapezoidal Thread Form for Small Parts: Delivers precise, repeatable thread profiles with consistent pitch and clean finishes on miniature components, enabling reliable performance in high-load applications.
- K20-Grade Carbide for Long Tool Life: High hardness and wear resistance reduce wear and extend tool life, preserving cutting accuracy through demanding threading tasks.
- Compact Size with Left-Hand Capability: 12.5 mm minimum diameter and 35 mm reach fit tight spaces, while left-hand threading expands compatibility across common designs and machines.
Together, these features help you tackle small-threading tasks with confidence, delivering accurate results fast and with less downtime. The tool’s durability and broad machine compatibility streamline setups and inventory, so you can finish jobs on time without sacrificing finish quality or repeatability.
