Description

The Carmex Carbide Tiny Tools - Small Threading UNJ Tool (MIR) is a precision carbide cutting tool designed for small-diameter threading tasks. Featuring a UNJ thread design, it delivers high-precision threads on compact workpieces, making it ideal for micro-fasteners, fine components, and delicate assemblies. Its premium carbide construction ensures strong performance in demanding environments, while the small footprint is perfect for threading tight features with confidence.

Built to perform across a wide range of machines and systems, this tool combines size, strength, and versatility. With a 4.9 mm minimum diameter and a 15 mm reach, it accesses tight pockets and recessed areas without sacrificing accuracy, helping you complete small-thread projects quickly and consistently.

  • UNJ threading precision for small parts: Delivers accurate UNJ threads on tiny workpieces, helping you meet tight tolerances with minimal rework.
  • Premium carbide for durability and wear resistance: Hard, wear-resistant cutting edge maintains sharpness longer, reducing sharpening frequency and downtime.
  • Compact design with 15 mm reach for tight access: 4.9 mm minimum diameter and 15 mm reach let you thread in confined spaces and across a broad range of machines, increasing job flexibility and setup efficiency.

This Tiny Tool empowers operators, engineers, and technicians to achieve reliable, repeatable threading results in small components, improving workflow speed, consistency, and overall project quality without adding complexity to your setup.
