Carmex Carbide Tiny Tool - Boring Bar - MTR - BXC Grade - 2.5mm Minimum Diameter x 10mm Reach x R0.15

The Carmex Carbide Tiny Tool is a precision boring bar built from solid carbide, engineered for micro-scale machining where rigidity and accuracy matter. While optimized for boring, it also handles light turning tasks, delivering steady, repeatable results on small-diameter features.

Designed for a wide range of users—from engineers and machinists to hobbyists—the tool's 2.5 mm minimum diameter, 10 mm reach, and R0.15 corner radius let you access tight pockets and finish small bores cleanly. It is offered in two coating grades within the Carmex Tiny Tool line: BXC with PVD TiN for low-speed stainless applications, and BMK with advanced PVD triple coating for higher heat resistance across materials.

• Ultra-compact micro-boring geometry: Access tight bores and small features with a 2.5 mm minimum diameter, 10 mm reach, and a precise R0.15 corner, all in a rigid solid-carbide bar for consistent, finish-ready cuts.
• TiN-coated BXC grade for stainless steel at low speeds: PVD TiN coating reduces wear and extends life when working with stainless steels at lower cutting speeds (ISO P30-P50 / K25-K40), delivering reliable, repeatable results.
• BMK option for high-heat, broad-material performance: Sub-micron BMK grade with triple PVD coating (ISO K10-K20) delivers excellent heat resistance, smoother cutting, and versatility across materials.

With the Carmex Carbide Tiny Tool, you gain a reliable micro-boring solution that fits in compact holders while delivering consistent bore quality, longer tool life, and reduced downtime. The combination of rigid carbide, precise geometry, and coating options means fewer tool changes, cleaner finishes, and predictable results across a range of materials and applications—from stainless steels to harder alloys—helping your workflow move forward more efficiently and with confidence.
