Carmex Carbide Tiny Tool - Boring Bar - MTR - BMK Grade - 5.1mm Minimum Diameter x 30mm Reach x R0.1

The Carmex Carbide Tiny Tool is a compact, solid carbide boring bar designed for precise internal work and general turning on small-diameter parts. With a 5.1 mm minimum diameter, a 30 mm reach, and a nose radius of R0.1, it delivers accurate bores in tight spaces while maintaining clean surface finishes.

Available in two high-performance grades, BXC PVD TiN and BMK with advanced PVD triple coating, this tiny tool handles a wide range of materials. BXC is optimized for low cutting speeds and works well with stainless steels, while BMK combines sub-micron grit with exceptional heat resistance for maximum performance and smooth cutting across many materials.

• Compact reach and bore capability: 5.1 mm minimum diameter with a 30 mm reach lets you access deep, hard-to-reach bores in small workpieces without flipping to a different tool, reducing setup time and tool changes.
• Two optimized coating grades for versatile materials: BXC TiN coating excels at low-speed stainless steel cutting, and BMK’s sub-micron grade with triple PVD coating delivers high heat resistance and smooth cutting across a broad material range.
• Rigid carbide for consistent, reliable cuts: Solid carbide construction provides stiffness and long tool life, delivering stable performances, reduced chatter, and repeatable hole diameters across production runs.

Using the Carmex Tiny Tool helps you complete precise internal features more efficiently, improves surface finish consistency, and lowers downtime from tool changes. Its compact footprint, proven coating options, and durable carbide construction make it a dependable choice for both detailed prototypes and small-bore production work.
