Carmex Carbide Tiny Tool - Boring Bar - MTL - BMK Grade - 4.1mm Minimum Diameter x 22mm Reach x R0.05 (Left Hand)

Carmex Carbide Tiny Tool - Boring Bar - MTL - BMK Grade is a solid carbide bar designed for precision boring with the versatility to handle general turning tasks. It features a compact 4.1 mm minimum diameter, a 22 mm reach, and a left-hand R0.05 nose to deliver accurate, controlled cuts in tight features and small components.

• Compact, precise boring bar geometry: The small 4.1 mm minimum diameter with a 22 mm reach provides access to tight bores while preserving rigidity for clean, repeatable finishes.
• Coating options for performance across materials: Choose BXC TiN-coated grade for low-speed cutting and stainless steels, or BMK sub-micron grade with a triple PVD coating for excellent heat resistance and smooth cutting across a broader material range.
• Left-hand cutting geometry with a fine R0.05 nose radius: Left-hand orientation and a precise nose radius help reduce chatter and improve surface quality in constrained pockets and intricate features.

This tiny carbide tool is built to simplify setups and extend tool life, delivering reliable results across boring and general turning applications. The dual-grade coatings enhance wear resistance and thermal stability, helping you maintain consistent performance from lightweight aluminum work to demanding stainless steel passes. Whether you’re refining a delicate bore or finishing a small-diameter feature, this tool offers dependable stability, predictable feeds, and smooth cutting control that supports faster cycles and fewer tool changes.
