The Carmex Carbide Tiny Tool is a threading bar engineered for tight spaces and precise partial-profile threads with a 60° geometry. Designed for engineers, technicians, and hobbyists who need repeatable results in small bores, it features a compact 3.2 mm minimum diameter and a 15 mm reach, with left-hand threading options to expand your capabilities. The tool is suitable for challenging tasks where bore sizes are limited, including delicate setups where clearance is at a premium.

Two high-performance carbide grades with protective coatings extend life and versatility. BXC TiN-coated carbide excels at low cutting speeds and performs well with stainless steels (ISO P30-P50 / K25-K40). BMK-grade carbide uses a sub-micron structure with a advanced PVD triple coating for maximum heat resistance and smooth cutting, making it a robust general-purpose choice across materials. The design also specifies a minimum bore diameter of 1.2 mm / 0.05 in for flexible small-bore threading.

• 60° partial-profile threading geometry: Delivers clean, repeatable threads in confined spaces, reducing setup time and improving first-pass accuracy.
• Coated carbide for durability and versatility: BXC TiN coating supports low-speed cutting on stainless steels, while BMK’s triple coating offers exceptional heat resistance and smooth cutting for broader material use.
• Compact, left-hand tool with precise reach: 3.2 mm minimum diameter, 15 mm reach, and a 1.2 mm minimum bore compatibility to handle small, tight bores and left-hand threading tasks efficiently.

This tool helps you streamline threading workloads by delivering reliable, consistent results across a range of materials. Its coated carbide construction reduces wear, extending tool life and minimizing downtime, while the compact geometry and left-hand orientation expand your option set for intricate assemblies. For shops aiming at precise, repeatable threads in small bores, the Carmex Tiny Tool provides predictable performance and steady finishes pass after pass.
