The Carmex Carbide Tiny Tool is a compact broaching cutter designed to create precise internal hex keyways inside blind or through holes on CNC machines. It is suitable for holes with a minimum diameter of 4.9 mm. It works with standard Tiny holders (SIM…H#) and can be mounted in either the turret or the spindle for flexible, space-efficient setups.

Crafted from BMK-grade carbide with a sub-micron finish and an advanced PVD triple coating (ISO K10–K20), this tool delivers excellent heat resistance and smooth cutting action, ensuring consistent results across a wide range of materials.

• Internal keyway broaching for tight holes: Delivers clean, accurately sized keyways in blind or through holes with minimal burrs, improving fit and reliability in assembled components.
• Durable carbide with triple coating: Sub-micron BMK-grade carbide with a PVD triple coating reduces wear and heat buildup, extending tool life and maintaining precision through long runs.
• Easy CNC integration with Tiny holders: Compatible with standard Tiny holders and mountable in turret or spindle, enabling quick setup and flexible workflow across different machines.

With this tool, you gain reliable, repeatable keyway performance that supports tighter tolerances, faster cycles, and less downtime, helping you meet demanding manufacturing and assembly needs with confidence.
