Carmex Carbide Tiny Tool - Boring Bar is a compact, solid carbide bar designed for precise internal boring and versatile turning tasks. With a left-hand orientation and a 6.1 mm minimum diameter, it reaches 22 mm into the workpiece and features a small R0.2 nose to help you achieve tight, accurate bores. This tool is ideal for engineers, machinists, and hobbyists who need reliable performance in a variety of materials, including stainless steels.

• Compact boring bar geometry: Delivers precise internal features with a 6.1 mm minimum diameter, 22 mm reach, and a left-hand R0.2 nose for clean, consistent cuts across a range of workpieces.
• Coatings optimized for versatility: Choose BXC TiN coating for low-speed cutting of stainless steels (ISO P30-P50 / K25-K40) or BMK triple-coated sub-micron carbide for high heat resistance and smooth cutting across materials (ISO K10-K20).
• TNX-grade carbide for reliability: Built from durable TNX-grade carbide to provide rigidity and wear resistance, delivering long tool life and stable performance in both boring and turning tasks.

This Tiny Tool borers into sized, dependable performance across a wide range of materials thanks to its specialized coating options and robust carbide core. The combination of precise geometry, left-hand orientation, and wear-resistant hard coating helps you achieve repeatable bores with smooth finishes, reducing downtime and improving workflow. Whether you’re producing tight internal features in stainless steel or performing general turning operations, this tool is designed to help you complete jobs with confidence and consistent results.
