Carmex Carbide Tiny Tool - Boring Bar - MTR - BMK Grade - 6.1mm Minimum Diameter x 22mm Reach x R0.05

The Carmex Carbide Tiny Tool is a solid carbide boring bar designed for precision in tight spaces. With a 6.1 mm minimum diameter, a 22 mm reach, and a nose radius of R0.05, it is ideal for small-diameter boring and general turning. This compact tool suits engineers, machinists, and hobbyists who need clean, accurate finishes in restricted setups.

Available in BMK Grade, a sub-micron grade with advanced PVD triple coating for extremely high heat resistance and smooth cutting. It also comes in BXC Grade, a PVD TiN coated option optimized for low cutting speeds and a wide range of stainless steels (ISO P30-P50 / K25-K40). Together, these coatings provide versatile performance across materials while you stick with one family of carbide bars.

• Ultra-compact boring bar design: The 6.1 mm diameter, 22 mm reach and R0.05 nose radius deliver precise holes and shoulders in tight spaces, enabling reliable boring and turning without repositioning parts.
• Coating options engineered for versatility: BXC TiN coating supports low cutting speeds for stainless steels (ISO P30-P50 / K25-K40), while BMK’s sub-micron grade with triple PVD coating delivers high heat resistance for demanding materials and smooth cutting.
• Rigid carbide construction for long life: Solid carbide core provides stiffness and durability, with coatings that reduce wear and heat buildup to extend tool life and maintain consistent finishes across jobs.

This tool helps you streamline setups, reduce tool changes, and consistently produce accurate finishes across a range of materials—from stainless steels to general metals. The combination of a compact form factor and durable coating technology minimizes downtime, improves surface finish, and supports reliable performance in both manual and CNC machining environments.
