Carmex Carbide Tiny Tool - Boring Bar - MTR - BXC Grade - 4.1mm Minimum Diameter x 30mm Reach x R0.2

The Carmex Carbide Tiny Tool is a solid carbide boring bar designed for precise internal work in tight spaces. With a minimum diameter of 4.1 mm, a reach of 30 mm, and a small nose radius of R0.2, it fits into tight bores and long pockets while delivering consistent, accurate cuts. While engineered for boring, it also handles general turning, giving you a versatile tool for a range of tasks in compact machine setups.

This product line offers two coating-grade options to match different materials and speeds: BXC TiN-coated grade for low-speed cutting on stainless steels (ISO P30-P50 / K25-K40) and BMK sub-micron grade with a triple PVD coating for extremely high heat resistance and smooth cutting across a wide range of materials.

• Ultra-compact bore bar with 4.1 mm min diameter and 30 mm reach: Access tight bores and long pockets with minimal tool deflection for precise internal features and efficient turning.
• TiN-coated BXC grade for stainless steel at low cutting speeds: Reduces friction, extends edge life, and delivers consistent results on stainless steels (ISO P30-P50 / K25-K40).
• BMK sub-micron grade with triple PVD coating for high heat resistance: Provides smooth cutting and broad material compatibility, making it a reliable general-purpose option for a wide range of materials.

When you need a precise, durable tool for small bores and hard-to-reach features, the Carmex Tiny Tool delivers dependable performance. Its compact geometry, coated grades, and robust carbide construction help improve hole quality, reduce downtime, and extend tool life across boring and turning tasks—so you can finish projects faster with confidence.
