The Carmex Carbide Tiny Tool – Threading, MIL 55° Partial, BMK Grade, with a 5.1 mm minimum diameter and 15 mm reach (Left Hand) is a compact, precision threading solution designed for tight spaces and partial‑profile threads. This tool is ideal for engineers, fabricators, and hobbyists who need reliable performance in small bores without sacrificing accuracy or finish.

It belongs to a versatile family of partial-profile threading bars that are compatible with 55° profiles. The tool supports a minimum bore diameter of 1.2 mm (0.05 in), making it suitable for a wide range of applications, including stainless steels and other common materials.

• 55° partial-profile threading compatibility: Optimized for 55° threads and partial-profile operations, delivering accurate engagement and clean starts in small bores (works down to a 1.2 mm / 0.05 in minimum bore).
• Premium coating options (BMK & BXC): BMK is a sub‑micron grade with triple PVD coating for extremely high heat resistance and smooth cutting across materials; BXC is a TiN‑coated grade tuned for low cutting speeds and excellent stainless steel performance (ISO P30‑P50 / K25‑K40).
• Left-hand threading, compact size, and reach: 5.1 mm minimum diameter with a 15 mm reach, designed for left‑hand threads and access in tight, space‑constrained features.

This tool delivers reliable, efficient threading with durable coatings that help extend life and maintain a smooth, consistent cut across a broad material range. Its compact geometry and left‑hand orientation simplify setup in constrained spaces, helping you reduce downtime and improve workflow in small‑bore projects.
