The Carmex Carbide Tiny Tool is a solid carbide bar engineered for face grooving applications. It delivers a full-radius, rounded groove with a 6 mm minimum diameter and a 1 mm groove width. This right-hand tool, crafted in MZR grade K20 carbide, is built for durability and dependable performance in both milling and turning setups.
The tool’s full-radius geometry creates rounded grooves rather than straight cuts, providing smoother transitions and better seating in housings and bearing areas. This design reduces finishing steps and helps parts achieve consistent fit from the first part.
- Full-radius groove geometry: Produces rounded grooves with a smooth, continuous profile that improves seating and reduces post-cut finishing.
- Premium MZR K20 carbide: Delivers high hardness and wear resistance for longer tool life and stable performance under demanding cuts.
- Compact, right-hand design with precise sizing: 6 mm minimum diameter and 1 mm groove width, engineered for reliable results in tight pockets and standard machine setups.
Using this tool helps streamline groove machining by delivering consistent, ready-to-assemble grooves, reducing setup time and rework while maintaining tight tolerances. Its robust carbide construction supports longer runs and steadier cuts, boosting productivity and part quality across a range of metalworking applications.
