The Carmex Carbide Tiny Tool is a precision MDR (Thread Relief, Chamfering & Grooving) carbide cutting tool designed for very small features. Built for engineers, machinists, hobbyists, and assembly specialists, it excels at creating clean thread relief, chamfers, and grooves on tiny parts where space is tight. Crafted from premium TNX-grade carbide, it delivers consistent cuts, long wear life, and reliable performance in micro-machining tasks.

Its compact form—4.1 mm minimum diameter with a 0.8 mm reach and a 0.5 mm corner radius—lets you approach tight corners and restricted cavities without overcutting, helping you achieve accurate, repeatable results on delicate components.

• Ultra-compact reach for tiny features: 4.1 mm minimum diameter and 0.8 mm reach enable precise cuts in restricted spaces, ideal for thread relief, chamfers, and grooves on small parts.
• R0.5 corner radius for smooth finishes: The 0.5 mm radius reduces sharp edges, minimizes burrs, and delivers clean transitions on grooves and chamfers.
• TNX-grade carbide for durability: Premium carbide construction provides excellent wear resistance and stable, repeatable performance during micro-machining tasks, extending tool life.

With the Carmex Tiny Tool, you gain reliable, high-precision results in tight spaces, reducing rework and downtime. Its focused geometry supports consistent thread relief, clean chamfers, and accurate grooves, helping you complete delicate micro-machining tasks efficiently and with confidence.
