Carmex Carbide Tiny Tool - Boring Bar - MTR - TNX Grade - 3.1mm Minimum Diameter x 15mm Reach x R0.05

The Carmex Carbide Tiny Tool is a compact solid carbide boring bar built for precision in small-diameter work. With a 3.1 mm minimum diameter, a 15 mm reach, and an R0.05 nose radius, it delivers rigid, accurate cuts for tiny bores and pocket features. Crafted in MTR TNX grade, it provides dependable wear resistance under demanding conditions and can also handle light turning tasks.

• Ultra-compact boring bar for tight features: The 3.1 mm minimum diameter and 15 mm reach let you access small bores and pockets with minimal overhang, reducing tool deflection and improving size control and finish.
• Two coating options to optimize life and performance: BXC TiN coating is designed for low-speed stainless steel work (ISO P30–P50 / K25–K40), while BMK offers a sub-micron, triple-coated solution for higher heat resistance and smoother cutting across a broad material range.
• Rigid MTR TNX carbide core for reliable performance: Solid carbide construction with TNX-grade composition delivers durable wear resistance and stable cutting during both boring and turning tasks, helping maintain consistent tolerances and finishes.

This tiny tool is designed to enhance workflow by enabling precise, dependable boring in tight spaces while offering versatile performance across materials. The dual coating options let you tailor tool life and finish to your application, reducing downtime and rework. Whether you’re chasing tight tolerances in small bores or performing delicate finishing passes on stainless steel, this tool provides consistent results and confidence on every job.
