68 inches, width around 0.

45 inches – and the nut is M14 thread with a 9/16-inch thickness.

The set fits most standard ER11 spindles and works for milling, boring, drilling, tapping, you name it.
Easy to swap bits – no complicated tools needed – just pop the collet in, slide in your cutter, and tighten the nut.
Made from solid metal, so it holds up to regular shop use without wearing out fast.
