While I have found the case and the original packing materials, the 1/2 inch collet is not to be found. I hope someone can provide a source or interchange number as none of the usual suspects seem to stock it or have a time frame for delivery.
While I have found the case and the original packing materials, the 1/2 inch collet is not to be found. I hope someone can provide a source or interchange number as none of the usual suspects seem to stock it or have a time frame for delivery.Need (want) to make some tongue and grooves for a panel I'm building. Got a couple of Craftsman routers the 320-17542 being variable speed.
Since most of the router bit sets for t&g seem to be 1/2 inch, I am looking for a 1/2 inch collet for that router. It seems to have only come with a 1/4 inch, but the manual says it can take either.
I don't want to buy one and hope it works, so asking if anyone knows what will work.
Edit - seems the part number may be 3550721000 which some say came with the router. Guess I can go hunt for it and hope, as the outlets I checked all seem to list it as backordered.
It does look very much like it. Appears the Bosch collet may not protrude above the nut as much and may be a bit longer overall, but as long as the threads are the same it should likely work OK.It looks very close to the collet that fits the Bosch 1617 among many other Bosch routers as well as a bunch of DeWalts, and some Hitachi routers. If you can find someone with one of those routers then it might be worth comparing and then trying to interchange them if they look like they will. This thread has a list of the routers that use the 1617 type collet: . . . Be careful with the collets you have because getting a replacement from Sears or ereplacement parts might not be an option. We see a lot of people coming to the forum trying to find replacements for their Sears routers.
I am not comfortable trying to remove the collet from the nut, so I'll forgo the thread pitch until I can remove the router from the table and measure the shaft and pitch. Eyeball is "fine pitch" from what I see. The collet is "retained" and I am not sure how to compress it to remove it, without damage, or how I would get it back in.If I remember correctly it's a 19mm shaft with a thread pitch of 1.0 mm. If you get a measurement I'll go out to the shop and double check.
It was 20 mm diameter on the threads but still 1.0 pitch which is pretty fine on something that diameter. The bottom of the collet was 14.3mm, very close to what you got. If yours turns out to be 20mm shaft diameter then the 1617 type collet will probably work. That collet is so common that we can expect it to be around for a while. It's also available in a number of different sizes.I am not comfortable trying to remove the collet from the nut, so I'll forgo the thread pitch until I can remove the router from the table and measure the shaft and pitch.

From what I can mic out so far, the ID of the nut, tip to tip on the threads, seems to be .775 in or 19.685 mm, flat to flat, .994 in/ 25.25 mm, length .883 in/ 22.43 mm
Over all length of collet is .993 in / 25.22 mm, narrow end of collet taper .556 in/ 14.12 mm.
Removed the router from table and 1/2 inch collet and nut. Threaded shaft measures out at 19.8 mm. Close enough?
