The Carmex Carbide Tiny Tool – Threading, MIR edition, is a compact threading bar designed for precise 55° threads in tight spaces. With a 6 mm minimum diameter and a 15 mm reach, it’s built for micro-bore work and hard-to-reach features across a range of components.

This versatile tool supports 55° thread profiles and tolerates bore sizes down to 1.2 mm (0.05 in). It is offered in two coated grades to match material and cutting speed needs: BXC TiN-coated grade for low cutting speeds and broad stainless-steel compatibility (ISO P30-P50 / K25-K40); and BMK sub-micron grade with a triple PVD coating for extremely high heat resistance and smooth cutting across a wide material range. It’s a general-purpose solution designed to handle a variety of materials with reliable, repeatable results.

• 55° Partial-Profile Design for precise threading: Optimized for partial-profile 55° threads in tight bores, delivering accurate thread geometry in restricted spaces.
• BXC TiN-coated grade for stainless steels and low speeds: Engineered for low cutting speeds with excellent wear resistance on stainless steels, helping extend tool life and maintain steady performance (ISO P30-P50 / K25-K40).
• BMK grade with triple PVD coating for high heat resistance: Sub-micron coating delivers maximum heat tolerance and smooth cutting across a broad material set, supporting reliable performance under demanding conditions.

This Tiny Tool offers a dependable, flexible solution for small-diameter threading tasks. Its compact geometry and coating options help you achieve consistent results across materials, reduce setup and tool-change frequency, and maintain steady productivity on micro-bore projects.
