Carmex Carbide Tiny Tool - Boring Bar - MTR - BMK Grade - 7.1mm Minimum Diameter x 30mm Reach x R0.2

The Carmex Carbide Tiny Tool is a compact solid carbide boring bar engineered for precision in tight bores and versatile enough for general turning. With a 7.1 mm minimum diameter, a 30 mm reach, and an R0.2 corner radius, it delivers stable, repeatable cuts on small to mid-size workpieces. Its coated grades are designed to perform across a range of materials, making it a reliable choice for both production environments and shop floors.

Two optimized coating grades expand its applicability: the BXC TiN-coated option is ideal for low cutting speeds on stainless steels (ISO P30–P50 / K25–K40), while the BMK grade features a sub-micron substrate with a triple PVD coating for extremely high heat resistance and smooth cutting across a broad material spectrum (ISO K10–K20). This combination gives you dependable performance from a single tool family.

• Dual coating options for versatility: BXC TiN-coated grade supports low-speed cutting on stainless steels, and BMK with triple PVD coating delivers high heat resistance and smooth cuts across a wide range of materials, enabling one tool to handle multiple jobs.
• Compact geometry for tight bores: 7.1 mm minimum diameter, 30 mm reach, and R0.2 corner radius provide precise, stable boring and clean finishes in confined cavities.
• Solid carbide durability for reliable performance: Built for general-purpose use across materials, delivering long tool life and consistent results with reduced downtime.

This tool helps you finish parts faster with tighter tolerances, fewer tool changes, and repeatable results in both boring and turning operations. Designed for engineers, machinists, and technicians who value dependable, high-precision performance from a compact, robust carbide bar.
