Carmex Carbide Tiny Tool - Boring Bar - MTL - BXC Grade - 4.1mm Minimum Diameter x 15mm Reach x R0.05 (Left Hand)

Carmex Carbide Tiny Tool is a compact, solid carbide boring bar designed for small-diameter work and tight setups. With a 4.1 mm minimum diameter and a 15 mm reach, it accesses narrow bores and supports both boring and general turning tasks. The tool features a left-hand orientation with a precise R0.05 nose radius for consistent finishes in confined spaces. It’s offered in two coated grades to match material and speed requirements: BXC TiN-coated for low-speed cutting and stainless steels, and BMK sub-micron grade with a triple PVD coating for high heat resistance and smooth cutting across a wide range of materials.

• Small-diameter, long-reach design: 4.1 mm minimum diameter and 15 mm reach let you access tight bores and perform precise boring where space is limited.
• Coated carbide grades for versatility: BXC TiN-coated grade supports low-speed cutting and stainless steels (ISO P30-P50 / K25-K40); BMK with triple PVD coating offers high heat resistance and smooth cutting for various materials.
• Left-hand geometry with R0.05 nose: Left-handed orientation and a fine nose radius provide predictable chip flow and clean bore finishes in challenging setups.

This tiny carbide tool helps you streamline setups and improve bore finishes in tight spaces. The two coating options extend tool life, reduce wear, and provide consistent performance across a range of materials, so you can move from prototype to production with confidence. By delivering stable cutting action and reliable results, it supports faster cycles, fewer passes, and improved workflow in both boring and general turning tasks.
