The Carmex Carbide Tiny Tool - Boring Bar is a precision micro-machining tool crafted from solid carbide. With a 1 mm minimum diameter, 6 mm reach, and an R0 corner, it’s built for tiny bores and tight tolerances. Designed to thrive in boring applications but equally capable for general turning, it helps you achieve clean, accurate cuts in hard materials.

Two advanced coating options give you the right balance of wear resistance and performance. The BXC grade features a PVD TiN coating optimized for low cutting speeds and excellent compatibility with stainless steels (ISO P30-P50 / K25-K40). The BMK grade uses a sub-micron carbide with a triple PVD coating for exceptional heat resistance and smooth cutting across a wide range of materials.

• Ultra-small micro-bore capability: 1 mm minimum diameter with 6 mm reach and R0 geometry enables precise holes in tight spots, reducing tool deflection and improving wall quality.
• BMK sub-micron carbide with triple PVD coating: Delivers exceptional heat resistance and smooth cutting for longer tool life and reliable performance across many materials.
• BXC TiN coated grade for low-speed stainless cutting: Optimized for low cutting speeds with stainless steels, providing reduced wear and consistent finishes (ISO P30-P50 / K25-K40).

This tool helps you maintain tight tolerances, reduces downtime, and provides consistent results across micro-boring and turning tasks. Its rigid carbide construction and coated surfaces ensure reliable performance even in demanding materials, making it a dependable choice for shop floors, job shops, or on-site work.
