adapter bushings (5/5), Feb 23, 2013

By Jeremy M (Fillmore ca US)

Works great in my DeWalt 611, bought the 1/8 and 3/16 and both work GREAT. I am ordering a second set because ill use them so much on my cnc.

Totally enclosed ball bearings. By replacing your router bit's bearing with a bearing that has a smaller or larger Outer Diameter, you can achieve a different depth or profile.
