R8 to 2MT Sleeve

The fit on my mill is spot-on—the hardened steel takes the wobble out of using 2MT tooling in an R8 spindle. It’s been a solid upgrade for my lathe work, and the precision grind shows in every cut I’ve made.

I've used this sleeve for a few months now, and it holds my 2MT drill chucks securely in the R8 spindle without any play. The precision ground taper fits cleanly every time, making tool changes quick and hassle-free on my mill.

The hardened and precision-ground finish is the first thing I noticed—it slides into the R8 spindle with a snug, reassuring fit. Chucking up a 2MT drill bit, I’ve had zero chatter on my mill so far, and the whole setup feels rock solid. Exactly what I needed for bench work.
