Keyless snap on chuck for Makita router. One would think I would have tried this search on the net before rambling on in here... One would be wrong.
Also ran into a couple of high speed Air drills that had similar rpm's to smaller routers and integrated keyless chucks.
For the minis out there - dremel produces a similar snap in model.
I'll eventually get around to ordering this thing, checking it out (unless discontinued) and seeing if it chatters my teeth out. If anyone else gets there first let me know.
