Description

The Carmex Carbide Tiny Tool is a compact, all-in-one cutting solution engineered for drilling, boring, chamfering, turning and facing in a single bar. With a 4 mm drill diameter and a reach of 10 mm, it excels at small features, tight pockets, and short overhangs, helping you reduce tool changes and shorten machining cycles.

Visible in the tool image is a blue-coated cutting portion paired with a robust silver shank, reflecting a design built for reliable, repeatable performance. This general-purpose Tiny Tool is suitable for a wide range of materials and applications, from hobbyist projects to professional manufacturing environments.

  • Multi-task versatility: One tool handles drilling, boring, chamfering, turning and turning and facing tasks, reducing tool changes and shortening cycle times for faster production.
  • Premium carbide and triple PVD coating: Sub-micron BMK carbide with an advanced triple coating (ISO K10-K20) delivers excellent wear resistance, high heat tolerance, and smooth cutting across materials.
  • Optimized geometry for reliable performance: Carefully engineered cutting geometry provides stable, chatter-free operation in tight spaces, ensuring consistent finishes and longer tool life.

The Carmex Tiny Tool helps you streamline workflows by consolidating multiple operations into a single pass, reducing downtime and tool inventory while delivering reliable, repeatable results. Its high-heat resistance and durable coating support consistent performance from first cut to finish, making it a trusted choice for engineers, buyers, tradespeople, hobbyists, and workshop professionals alike.
