The Carmex Carbide Tiny Tool is a compact threading bar engineered for internal threads in tight bores. With a 60° partial-profile design (MIR) and a 6 mm reach, it excels in applications where access is limited, making it a practical choice for precision small-bore components. It’s suitable for engineers, machinists, and hobbyists who need reliable, repeatable threading in restricted spaces.

This tool combines two high-performance coating options to cover a wide range of materials and speeds. The BXC grade features a PVD TiN coating optimized for low cutting speeds, delivering steady performance when threading stainless steels and other tough alloys. The BMK grade is a sub-micron, triple-coated option that provides excellent heat resistance and smooth cutting, making it a versatile general-purpose choice for materials across the ISO range.

• BXC TiN-coated grade for low-speed threading: Reduces friction and wear at slower feeds, helping you achieve stable, repeatable threads in stainless steels (ISO P30-P50 / K25-K40) and other challenging materials.
• BMK sub-micron grade with triple coating for heat resistance: Delivers maximum performance under higher heat and demanding cuts, with smooth cutting action that supports reliable finishes across a broad material set.
• Small-bore capability with 1.2 mm minimum diameter and 6 mm reach: Enables precise internal threading in tight bores and confined spaces, expanding workholding options and reducing the need for secondary operations.

Designed for consistent results and long-term value, the Carmex Carbide Tiny Tool helps you complete precision internal threads with confidence. The combination of coating options, compact geometry, and targeted reach supports efficient workflows, minimizes downtime, and delivers reliable performance across materials—from stainless steels to general-purpose applications.
