Carmex Carbide Tiny Tool - Broaching Hexagon Keys - HK - BMK Grade - 2.2mm Minimum Diameter

The Carmex Carbide Tiny Tool is a precision broach bit designed to create clean internal keyways inside blind or through holes on CNC machines. It works with standard Tiny holders (SIM…H#) and can be mounted either in the machine’s turret or in the spindle, giving you flexible integration with existing setups. This variant features a 2.2 mm minimum diameter and BMK-grade carbide for reliable performance.

As part of the HK broaching system, it’s engineered to machine internal keyways with a smooth cutting action and excellent heat resistance. The tool uses a sub-micron grade carbide with an advanced PVD triple coating (ISO K10–K20) to deliver maximum performance across a wide range of materials.

• Internal keyway broaching for CNC: Enables precise, clean internal keyways in blind or through holes, reducing rework and improving fit quality on every part.
• Sub-micron carbide with triple PVD coating: Delivers exceptional wear resistance and smooth cutting, helping the tool last longer and maintain consistent results.
• Flexible mounting with Tiny holders: Compatible with standard Tiny holders and can be mounted in either the turret or spindle, making it easy to integrate into existing CNC workflows.

Using this tool helps you achieve reliable, repeatable keyway production, improves throughput, and enhances overall efficiency by delivering clean cuts with minimal downtime and consistent performance across materials.
