Carmex Carbide Tiny Tool - Boring Bar - MTR - TNX Grade - 4.1mm Minimum Diameter x 22mm Reach x R0.1

The Carmex Carbide Tiny Tool is a compact solid carbide boring bar designed for precise small-diameter bores and light turning. With a 4.1 mm minimum diameter and a 22 mm reach, it excels in confined cavities and deep holes, delivering accurate, repeatable results. The nose radius of R0.1 helps produce clean finishes in tight geometries, making it a dependable choice for small-part machining.

Coating options expand its versatility: BXC is a PVD TiN-coated grade optimized for low cutting speeds and stainless steels (ISO P30-P50 / K25-K40), while BMK is a sub-micron grade with a triple PVD coating for high heat resistance and smooth cutting. This dual capability supports a broad range of materials and cutting conditions, reducing tool swaps in mixed-material workflows.

• Ultra-compact size with long reach: The 4.1 mm minimum diameter and 22 mm reach allow you to bore deep, narrow holes and machine in tight pockets without sacrificing accuracy. The R0.1 nose radius helps maintain a stable cutting edge and consistent finishes in restricted spaces.
• Coatings for versatility across materials: BXC TiN coating improves wear resistance at low speeds on stainless steels, while BMK’s sub-micron grade with triple PVD coating delivers high-temperature performance and smoother cutting across a wide material range. Choose the coating that fits your material and cycle time.
• Durable carbide construction for reliable performance: Solid carbide construction and precise geometry provide rigidity and long tool life, resisting wear and chatter to deliver dependable, repeatable cuts in boring and turning tasks.

This tiny tool helps you tackle challenging small-diameter bores with confidence, improving first-pass accuracy and surface finish. With its robust coatings and optimized geometry, you can switch between stainless and other materials without swapping bars, streamline setups, reduce downtime, and achieve consistent results across jobs.
