Carmex Carbide Tiny Tool - Boring Bar - MTL - K20 Grade - 4.1mm Minimum Diameter x 22mm Reach x R0.2 (Left Hand)

Carmex Carbide Tiny Tool – Boring Bar designed for precise small-diameter work. This solid carbide bar is engineered for boring applications and also handles general turning tasks, delivering reliable performance in tight spaces. The tool features a compact 4.1 mm minimum diameter, a 22 mm reach, and a precise R0.2 nose radius in a left-hand configuration, making it ideal for meticulous small-bore work.

Two high-performance coatings adapt the tool to different materials and cutting speeds. The BXC coating with PVD TiN provides efficient cutting at lower speeds for a wide range of stainless steels, while the BMK grade uses a sub-micron carbide with an advanced triple PVD coating for exceptional heat resistance and smooth cutting across diverse materials. This makes the tiny tool versatile enough to cover many machining needs without changing tools.

• Small-diameter, long-reach boring geometry: 4.1 mm minimum diameter with a 22 mm reach and a precise R0.2 nose radius allow accurate bore entry in tight pockets and clean hole finishes with stable cutting.
• Coatings that match your material and speed: Choose BXC TiN for low-speed stainless steel work or BMK’s triple-coated, sub-micron carbide for high-heat performance and smooth cutting across a broad material range.
• Durable carbide construction for consistent results: Solid carbide with optimized geometry delivers repeatable hole quality and extended tool life, reducing downtime and maintenance in busy shops.

This tiny carbide tool helps you achieve tight tolerances, consistent finishes, and reliable performance in small-diameter bores. Its dual-coating versatility and robust carbide construction support efficient setups, longer tool life, and steady results across stainless steels and other common machining materials.
