ICarbide 5/16 ER20 Collet – Ultra Precision 0.0002 TIR For CNC Tool Holders (Single)

Okay, CNC folks and machinists, listen up.

If you’re chasing that perfect finish and need your tools running absolutely true, you gotta check out this collet.

It’s a single 5/16-inch ER20 collet from iCarbide, and the specs on this thing are sweet.\n\nWe’re talking about a TIR (that’s runout, for the uninitiated) of just 0.0002 inches, or 5 microns.

Yeah, you read that right.

That’s ultra-precision stuff, meaning your tool is gonna spin with almost zero wobble.

That translates to better surface finishes, longer tool life, and just cleaner work overall.\n\nIt’s made in Taiwan, which is known for some serious quality in the machining world, and it’s brand spankin’ new in the package.

The part number is ER20516um, and it’s got a UPC 793574706590 if you need to look it up.\n\nWhether you’re doing production runs or one-off projects in the garage, having a collet this accurate in your holder makes a world of difference.

Grab one, or grab a few, and keep your setup tight.
