Omega Products ER40 Collet Standard Precision - 10 Micron Run-Out - 22mm - 21mm

Omega Products ER40 Collet Standard Precision is engineered to deliver repeatable grip and truly concentric tool paths for everyday machining. Designed to clamp round stock in an ER40 collet chuck, this collet achieves a tight 10 micron run-out, reducing run-out-induced error right at the cutting edge for cleaner cuts and longer tool life.

Key advantages you’ll notice in real-world work:

• 10 micron run-out tolerance for superior concentricity in milling, drilling, and finishing passes. Expect cleaner slots, tighter thread forms, and improved surface finishes on aluminum, brass, and steel.
• Consistent internal bore and uniform wall thickness across the entire clamping range, yielding repeatable results when swapping tools or stock sizes.
• ER40-standard compatibility designed to work with standard ER40 collet chucks and common machining setups—making tool changes fast and reliable.
• Durable construction in hardened steel that resists wear from repeated clamping and release cycles, maintaining accuracy over long-term use.
• Focused on general purpose machining so you get predictable performance for everyday operations, from pocketing and profiling to light roughing and finishing passes.

Who benefits most: machinists, hobbyists, and shop technicians who demand repeatable grip and tight tolerances without stepping up to premium/high-cost collets. If your workflow relies on concentric tool paths, consistent clamping force, and quick changeovers, Omega’s ER40 Collet Standard Precision is a reliable upgrade.

How it helps you stand out from the crowd: you’ll experience less chatter, more accurate hole locations, and better diameter control across runs, thanks to the 10 micron run-out design and precisely machined interface. This isn’t just a clamp—it’s a precision partner in your CNC milling, drilling, or engraving projects.

Tips for best results: ensure clean, deburred stock, and insert the collet square and fully seated in the chuck before tightening. Use proper torque as recommended for your machine, and avoid over-tightening which can damage the interface. Regularly inspect the collet’s slots for wear and replace if you notice any distortion or increased run-out.
