I too have an older Craftsman commercial 1/4 router that I would like to convert to 1/2. I see nothing on the House of Tools website that I think would work? Is it possible to make this conversion?

Thanks,
Glenn.

Guys, the reason you don't find 3/4" round over bits with a 1/4" shank is the weight involved. Were you to use an adapter it would be steel and would have a steel collet and nut. Then you add a heavier 1/2" shank bit. See my point? Even if somebody made one I would not want to chance it. Don't forget this would also change the geometry of the bit location. You would have virtually no useable adjustment. My Craftsman Commercial was mounted to a Biskit adapter and kept there. Perhaps you might consider building one of the mortising or horizontal tables and dedicating your Commercial router to it? Safety first guys.

Rick,

I sent an email to Sears Customer Support to find out about a 1/2 collet for your Craftsman router. The response I got surprises me. The person said that Sears does not have interchangeable collets for their routers. I didn't question that response but I find it odd that they don't have what you want. Sorry to be the one to give you that bit of negative news.

Bill, most Craftsman routers don't use a normal collet and nut. They designed the shaft to accept 1/4" bits and the collet is formed onto the shaft end. This design is very practical for a couple reasons. You dont have to worry about seating the bit wrong as you do with a normal collet. You wont ever lose the collet, and I'm sure it is easier to learn with for beginers.

I have the very same router I think..... I have to check the number but it sounds right, keep in mind I got mine in 1975 or 1976..... I check a while back about a new collet and found that the orginal one has now been replaced by a newer one and not a craftsman part. I think it was about $6.50 US but by the time they tacked the tax and HIGH postage I decided not to spend the money.... after all the old one still works.

Having said all that I think like it or not it is time for a replacement or addition router. I too got to the point where I was limited by the 1/4" and got my first Porter Cable 690. The old Sears one is listed as 1-1/2 HP as is the PC but the power difference was very noticeable in favor of the PC. After getting the new router I was sorry I waited so long.... it got my interest in routers going again and so it goes.

Hello,
I bought the 1/2 inch collet for my 315.xxxxx and found that I had a phillips head screw inside at the bottom of the chuck to hold the router bit, that I could not get loose despite a large amount of liquid wrench and a weeks wait. I finally gave up and sent the collet back to sears. The price was reasonable but the shipping and handling charges were outrageous. I love my old 3 1/2 HP router but now that I know more, its uses are significantly reduced to freehanding.

I have the same router, but did you realize that the Phillips screw is a left hand thread. I'd always forget when switching collets.
