The Carmex Carbide Tiny Tool is a compact solid carbide boring bar designed for precision in small-diameter bores and tight turning operations. With a 4.1 mm minimum diameter, 15 mm reach, and an R0.1 nose, it excels at accessing confined features while maintaining consistent geometry.

Built for versatility, this tool is suitable for boring as well as general turning. It comes in coating families that optimize performance across materials: BXC is a PVD TiN coated grade aimed at low cutting speeds and works well with a wide range of stainless steels (ISO P30-P50 / K25-K40); BMK is a sub-micron grade with advanced PVD triple coating for exceptional heat resistance and smooth cutting, making it a reliable general-purpose option for materials across the spectrum.

• Access Tight Places with Precision: 4.1 mm minimum diameter, 15 mm reach, and an R0.1 nose radius enable accurate boring in restricted spaces and deliver clean, tight tolerances.
• Two Coating Families for Real-World Versatility: Choose BXC PVD TiN for efficient, low-speed cutting on stainless steels, or BMK’s sub-micron, triple-coated construction for high heat resistance and smooth cutting across a broad material range.
• Durable, Reliable Carbide Core: Solid carbide construction paired with advanced coatings provides long tool life, consistent finishes, and reduced downtime in demanding machining tasks.

This tiny boring bar is designed to improve workflow by enabling precise starts, smooth finishes, and reliable performance in tight pockets—whether you’re setting up a new part, performing finishing passes, or tackling challenging stainless components. Its compact form and coated options help you reach tight features with confidence, delivering dependable results batch after batch.
