The Carmex Carbide Tiny Tool is a 55° partial-profile threading bar designed for tight bores and limited tool access. With a 6 mm minimum tool diameter and a 22 mm reach, it’s ideal for engineers, machinists, and hobbyists who need precise, reliable threads in small-diameter workpieces. The tool supports minimum bore diameters as small as 1.2 mm (0.05 inch), making it a practical choice for compact assemblies and delicate components.

• 55° Partial-profile threading design: Specifically shaped to form high-quality threads in tight bores, delivering consistent engagement and reducing the need for rework in restricted access areas.
• Dual coating options for versatility: BXC TiN coating is optimized for low-cutting-speed work and wear resistance on stainless steels (ISO P30-P50 / K25-K40). BMK, a sub-micron grade with advanced PVD triple coating, delivers exceptional heat resistance for smoother cutting and longer life (ISO K10-K20).
• Compact size with extended reach: 6 mm minimum diameter and 22 mm reach, combined with a minimum bore diameter of 1.2 mm (0.05 in), enables threading in compact features and hard-to-reach pockets without compromising performance.

Using the Carmex Tiny Tool helps streamline small-diameter threading tasks by enabling reliable, repeatable results in confined spaces. The combination of specialized 55° geometry, robust carbide substrate, and purpose-built coatings reduces tool wear, minimizes downtime, and delivers smooth cuts across a broad range of materials—from stainless steels to general-purpose alloys—so you can complete projects with confidence and precision.
