Introducing the Carmex Carbide Tiny Tool for Threading (MIR, 55° Partial). This compact threading bar is engineered for precise 55-degree thread forms in the smallest bores, making it ideal for confined spaces and intricate assemblies. It can work in bores down to 1.2 mm (0.05 in) with a 4.1 mm minimum diameter and a 15 mm reach, helping you complete threads in tight locations without unnecessary disassembly.

Crafted from BMK-grade carbide and finished with an advanced PVD triple coating (ISO K10–K20), this tool combines extreme heat resistance with smooth cutting performance. The coating and geometry are designed to deliver reliable, long-lasting performance across a wide range of materials, providing a dependable threading solution for demanding production environments.

• 55° Partial-Profile threading design: Delivers accurate, repeatable 55° thread forms in small bores, reducing scrap and rework in tight assemblies.
• BMK-grade carbide with triple-PVD coating: Sub-micron wear-resistant grade with a high-heat-tolerant coating for durable, smooth cutting across materials.
• Compact form factor for tight spaces: 4.1 mm minimum diameter with 15 mm reach (bores down to 1.2 mm) to reach and thread in confined interiors without disassembly.

This tool supports efficient threading workflows by combining precise geometry, robust coating, and a compact profile that suits challenging small-bore applications. It helps you achieve reliable thread quality, minimizes downtime, and enhances overall productivity in precision machining tasks.
