Description
Don’t get caught in the middle of a job with a broken collet or collet nut. Always have a spare set on hand so you can get the job done! Includes 5 collets and 2 collet nuts.
Uses:
- Holding round‑shank end mills, drills and router bits precisely in an ER20 collet chuck system
- Ensuring minimal run‑out and high concentricity for precision CNC machining operations
- Providing a wide range of shank diameters—from small tool bits up to larger tooling—in one set
- Switching seamlessly between tool sizes to reduce downtime in production, prototyping or job‑shop environments
- Supporting woodworking, plastics, composites and soft‑metal machining on CNC routers or milling spindles
- Optimizing tool grip and reducing vibration for better surface finish and longer tool life
- Serving educational and training CNC labs for teaching proper precision tool‑holding techniques
- Enabling rapid adaptation of tooling setups for nested machining, short‑run parts or custom sign/display fabrication
- Compatible with ER20‑type collet nuts and chucks commonly used in spindle setups for routers and light‑milling machines
- Helping maintain consistent part quality by ensuring repeatable, stable tool clamping across different jobs
