Description

Omega ER20 Collet (9–10 mm) – Standard Precision is engineered for round shank clamping in an ER20 collet chuck. This single collet delivers dependable grip and repeatable performance for everyday machining tasks, from hobby work to small-shop production.

With a stated 10 micron run-out, this ER20 collet minimizes tool deflection during cutting. The result is cleaner holes, smoother milling passes, and better surface finish, especially on precision work where concentricity matters.

  • Clamping range: 9–10 mm (ER20 collet size)
  • Run-out: 10 microns (0.01 mm) for consistent tool alignment
  • Designed for use with standard ER20 collet chucks, enabling quick tool changes and reliable gripping
  • Ideal for general purpose machining, including milling, drilling, and light engraving with 9–10 mm shanks

Use scenarios bring the most value: secure small-diameter end mills or drills in CNC mills, drill presses, or engraving setups where precision is critical. By pairing this collet with your ER20 chuck, you gain predictable clamping force and repeatable results across multiple setups, reducing downtime and waste from misalignment.

Key benefits in real-world workspaces:

  • Consistent concentricity across setups minimizes runout-induced errors
  • Compact profile keeps clearance tight without sacrificing rigidity
  • Straightforward seating in the ER20 chuck promotes reliable tool retention

To maximize performance, ensure tool shanks are clean and fully seated before tightening, and match tool diameter to the 9–10 mm range. This Omega standard precision collet is a practical choice for shops that value dependable accuracy in routine machining without stepping into premium options.
