The Carmex Carbide Tiny Tool is a compact, high-precision cutting tool designed for small-thread relief, chamfering, and grooving. Built from premium BMK-grade carbide for durability and wear resistance, this MDR tool is engineered to handle tiny features with confidence. It features a 6.1 mm minimum diameter, a 1.4 mm reach, and a precise R0.5 edge, making it ideal for clean, repeatable work on small parts. The blue-shaft design provides quick identification and ease of handling in busy workshops.
- Premium BMK-grade carbide: Delivers exceptional hardness and wear resistance for longer tool life and consistently sharp cuts on small-diameter work.
- Compact reach with precise geometry: A 6.1 mm minimum diameter and 1.4 mm reach allow clean thread relief, chamfers, and grooves in tight spaces with reliable control.
- R0.5 edge radius: Designed for smooth finishes and burr-free results, helping maintain tight tolerances across multiple passes.
This tool is ideal for operators who frequently work in constrained areas where small, accurate cuts are essential. By combining threading relief, chamfering, and grooving in a single, carbide-based micro-tool, it helps streamline setups, reduce tool changes, and improve overall workflow—delivering repeatable, professional finishes on small parts and assemblies.
