The Carmex Carbide Tiny Tool (MDL) is a compact, high-precision cutting tool designed for small thread relief, chamfering, and grooving on miniature parts and components. Its focused geometry and sharp carbide edge enable accurate starts and clean finishes in tight spaces, making it a reliable choice for engineers, machinists, hobbyists, and shop floors alike. Built to the MDL specification with BMK-grade carbide, this tool delivers consistent performance where precision matters most.
- Compact geometry for tight workpieces: With a 5.1 mm minimum diameter and 1.2 mm reach, this tool accesses restricted features to perform thread relief, chamfers, and grooves accurately on small parts.
- Premium carbide for long tool life: Crafted from high‑quality carbide, it provides excellent wear resistance and durability, helping maintain cut quality over repeated uses.
- Left‑hand operation with a 0.5 mm radius: Designed for left‑hand cuts with a precise 0.5 mm corner radius, delivering clean relief and smooth finishes in challenging geometries.
Use this tiny tool to simplify delicate threading and edge prep on small components. Its precise geometry reduces the number of passes required, speeds setup, and helps you achieve repeatable results across batches, boosting productivity and part quality without frequent tool changes.
