Meet the Carmex Carbide Tiny Tool, a compact solid carbide boring bar designed for tight bores and precise depths. With a minimum diameter of 6.1 mm, a 35 mm reach, and a left-hand R0.2 geometry, it's ideal for accurate boring and reliable light turning in small parts. Built for engineers, machinists, and hobbyists who value dependable performance in constrained spaces.

• Small-diameter design for tight bores: 6.1 mm minimum diameter and 35 mm reach let you access confined bores and deep features without repositioning tooling.
• Left-hand, precision corner (R0.2) for smooth cutting: The left-hand orientation with a tight 0.2 mm corner radius delivers stable, clean inner profiles and reduces chatter on small-diameter workpieces.
• Two grade options for broad material compatibility: BXC is TiN-coated for low-speed cutting and performs well with stainless steels (ISO P30–P50 / K25–K40); BMK is a sub-micron grade with advanced PVD triple coating (ISO K10–K20) delivering higher heat resistance and versatile all-material performance.

This carbide boring bar is designed to deliver consistent, reliable results across a range of boring and light turning applications. The coatings and grade options are chosen to maximize tool life, reduce built-up edge, and keep cutting forces smooth, helping you finish parts with tighter tolerances and better surface finish in less time.
