The Carmex Carbide Tiny Tool for Threading is a compact, partial-profile threading bar designed for precise internal threads in tight bores. With a 6 mm minimum tool diameter and a 15 mm reach, this left-hand tool is ideal for confined spaces and small-diameter workpieces, making it a dependable choice for engineers, machinists, and hobbyists working with stainless steels or other demanding materials. It’s built to deliver consistent 55° threads in internal bores as small as 1.2 mm (0.05 in), helping you complete challenging tasks without multiple setups.

• 55° Partial-Profile threading: Optimized for internal threads using 55° profiles, enabling accurate, reproducible results in narrow bores and reducing the need for rework in tight spaces.
• Dual coating options for flexibility: Choose BXC with PVD TiN coating for efficient cutting at low speeds on stainless steels (ISO P30-P50 / K25-K40), or BMK with advanced PVD triple coating for exceptional heat resistance and smooth cutting across a wide material range.
• Compact left-hand tooling: Left-hand threading capability with a 6 mm minimum diameter and 15 mm reach, backed by carbide durability for long tool life in demanding internal threading applications.

This toolline is purpose-built for reliable, repeatable performance across materials and applications. Its precise geometry and coated carbide construction help you achieve clean, consistent threads with fewer passes, improving workflow efficiency and overall production quality while giving you the confidence to tackle small-diameter internal threading tasks with precision.
