Once the Musclechuck™ assembly has been installed on the router, it will enable the cutters to be exchanged with extreme ease. The Musclechuck™ assembly gives you easy access when changing cutters and eliminates the cumbersome use of wrenches. Along with its superior grip, it also gives you some extra length when using router plates (approx. 1/2") or a router table so the full length of the cutter can be used. Consequently, because of its extreme ease of use, no more dropped or damaged cutters or frustration will result when changing tools. The body of the new Musclechuck™ assembly is slotted in such a way that allows the tool shank to be held circumfrentially, when the cap screw is tightened. In the past, most quick-change chucks relied on one or more cams to retain the tool shank. However, the Musclechuck™ assembly doesn't contain a cam and because of it's superior holding capacity, larger cutters can be held more securely without damaging the shank of the tool.

Musclechuck for Milwaukee Router

Works great. Wish i had bought this a long time ago. SO much easier than messing with the 2 wrenches. Works as advertised. No vibration. So far only used it with a large (2 1/2") Base molding router bit. Very Happy with it and with the service from Woodline.


Works like a charm

Musclechuck -- Great Tool!

This chuck performs as advertised, making bit changes fast and easy. Highly recommended for those with router tables! Woodline shipped immediately upon order, and the chuck arrived sooner than expected.

No problems with the tool nor the store

It’s really very simple. Store what people want at a price they want to pay and make the buying process uncomplicated. Woodline did that. No hassles and a good deal.

Better Than Expected

Excellent chuck and so easy to replace bits. All routers should have this tooling. No more wrenches! I will order a few more for my other routers. No vibration, no concerns! Even with a bit so large it wouldn't fit through the opening in my table, the chuck worked perfectly.
