Carmex Carbide Tiny Tool - Boring Bar - MTL - BXC Grade - 3.7mm Minimum Diameter x 15mm Reach x R0.15 (Left Hand)

Carmex Carbide Tiny Tool is a compact, solid carbide boring bar engineered for small-diameter work. With a 3.7 mm minimum diameter, 15 mm reach, and left-hand geometry featuring a precise R0.15 nose radius, it delivers stable engagement and clean finishes in tight bores. While optimized for boring, its versatility also makes it suitable for general turning tasks on a range of materials.

Two coating grades give you the right balance of speed, heat resistance, and durability for different jobs. BXC TiN-coated grade is designed for low-cutting-speed applications and performs well with stainless steels (ISO P30-P50 / K25-K40). BMK is a sub-micron grade with advanced PVD triple coating, delivering extremely high heat resistance and smooth cutting for broad material compatibility.

• Compact, small-diameter design with 15 mm reach: Enables access to tight bores and tight pockets while maintaining rigidity for precise, consistent results.
• Two coating grades for versatile performance: Choose BXC TiN for efficient cutting on stainless steels at low speeds, or BMK for long tool life and smooth cutting across a wide range of materials.
• Left-hand geometry with a precise R0.15 nose radius: Supports predictable chip flow and stable, high-quality finishes in both boring and turning operations.

This tiny, carbide bore bar is built to enhance workflow by delivering reliable, repeatable results in constrained spaces. Its durable construction and coating options help reduce tool changes, improve surface finish, and extend tool life across demanding boring and turning tasks.
