The Carmex Carbide Tiny Tool (CML) BMK Grade is a compact, all-in-one cutting solution for drilling, boring, chamfering, turning and facing in a single bar. With a 4 mm drill diameter and a 10 mm reach, it excels in tight spaces and repetitive work, making it ideal for engineers, machinists, hobbyists, and workshops that value quick setup and reliable performance.
This tiny tool uses sub-micron grade carbide with an advanced PVD triple coating (ISO K10–K20) to deliver excellent wear resistance and smooth cutting across a range of materials. The left-hand configuration supports specific machining setups and reduces chatter, helping you achieve consistent finishes and predictable results.
- All-in-one multi-function design: One tool handles chamfering, drilling, boring, and facing, reducing tool changes and cutting cycle times so you can complete more parts per shift.
- Durable, wear-resistant coating: Sub-micron BMK carbide with a triple-layer PVD coating delivers long wear life and smooth cutting, even on harder materials, with high heat resistance.
- Precise left-hand 4 mm drill with 10 mm reach: Optimized for tight cavities and specific setups, this tool provides controlled depth and stable performance in demanding applications.
By consolidating multiple operations into one compact tool, the Carmex Tiny Tool streamlines workflows, reduces downtime from tool changes, and delivers consistent results across materials. Its durable carbide core and advanced coating resist wear and heat, helping you maintain accuracy and finish quality over long runs. Whether you're building prototypes or producing high-volume parts, this tool helps you finish faster with dependable, repeatable performance.
