ER25 Collet Set (R8 Shank)

Picked up a set for my milling projects, and the .040-inch gripping range is a lifesaver for swapping between end mills and drills without constant re-tooling. I've run it through several aluminum and steel cuts, and the accuracy is noticeably better than my old collets.

The grip range on these collets is impressive; I can switch between different end mill sizes without swapping holders. It took less than a minute to seat my first tool and run a test pass.

Swapped out my old solid holders for these and the .040-inch gripping range makes a real difference when I need to switch between different shank sizes mid-job. They seat quickly and hold end mills firmly without any wobble during cuts.
