Description

Precision you can rely on in every pass. The Omega ER40 Collet Standard Precision is engineered to clamp round tool shanks securely in your ER40 collet chuck, delivering consistent performance across milling, drilling, and metalworking tasks. With a tight 10 micron run-out, this collet set minimizes run-out-related errors and keeps tools running true through demanding machining cycles.

Key benefits at a glance

  • 10 µm run-out for exceptional concentricity and improved surface finishes on every cut.
  • ER40 compatibility means reliable compatibility with standard ER40 collet chucks for a wide range of tooling.
  • Robust construction forged from hardened steel with precision-ground interiors to maintain accuracy over time.
  • Multi-slot, uniform grip design delivers balanced clamping pressure around the tool shank, reducing wobble during high-speed machining.
  • Ideal for general purpose machining from light milling to precision drilling and tapping, where repeatable results matter.

Whether you’re assembling a compact home workshop or outfitting a precision shop, this ER40 collet set is crafted to minimize tool run-out and maximize holding power. The result is smoother tool operation, more accurate hole positions, and longer tool life thanks to evenly distributed clamping force. It’s the practical choice for hobbyists upgrading their rigs and professionals who demand dependable, repeatable performance in every run.

Designed to perform with standard ER40 collet chucks, the Omega Standard Precision collets are a reliable solution for secure tool holding. Keep your machining tight and your results consistent—choose a collet that prioritizes concentricity and durability at the core of your setup.
