Router bit Question - Weeker 1/4 Spiral

#273480 by bainin » Fri Aug 21, 2020 6:31 pm

I picked up this bit from Amazon and on receiving I am perplexed that I cant see an obvious way to change the bearing on it.

My assumption was there would be an allen head screw on top to remove the bearing-but there isn't-sorry for the fuzzy picture.

Is this some bit of esoteria I didnt have on 1/4 spiral bits? That they dont allow for bearing changes or just my bad luck on this particular one?

There are actually 2 separate bearings on it.

Its made by Weeker - which I seem to only be able to find on Amazon and no company website ...sigh.

If there is no lock ring or other hardware on the end to remove it, likely it is a press fit.

My experience with bearings on router bits is that if you oil them occasionally they will last as long as the bit so you likely will never need to replace it.

Thanks !

Well- the reason I wanted to change the bearing was to do a complementary curve using the router table. With the instructions I'm following, this requires a bearing diameter change to recreate the original curve on 2 pieces for a good match.

Luckily, I discovered that my old bushing set actually works with my router table , it was originally used on a plunge router-I didnt know i had a table insert which supported the bushings as well.

So-I can recreate the bearing diameter change with a bushing set instead .

I have the sneaking suspicion that the tools I have in hand are very capable, but they are limited by my ability to know how to use them :)

I just purchased an almost identical router bit last week, but mine was from Whiteside. I am used to bearing router bits, but never purchased a 1/4" shank bit like this before, so this tiny end bearing is new to me as well. When I went to use it, I found the bearing to be stiff to turn (even lubricated). I went ahead and used it briefly, but when I stopped the bearing had discolored indicating it was likely overheated. If anyone has experience with this style bearing on a router bit and has some tips I would appreciate it. The bit cut fine, but I would really expect the bearing to be free turning right out of the package. Perhaps I got a "lemon" when I purchased this bit or am I doing something wrong???

I did a little bit of flush trimming with mine on 3/4" birch ply. I didn't observe
any bearing darkening and mine spun freely out of the box.

It might be a bad one.

That bit is defective. I have one from Whiteside just like it and have routed 30 or 40 feet of hardwood with not a hint of burning. Email Whiteside they will send you a new one.

Jack,

Thanks. I appreciate it. Yeah, I was going to return it to Amazon and say it was defective. It was supposed to ship directly from the manufacturer, but for all I know this could have been a knock-off product that was just labeled as being from Whiteside.

The first ever whiteside bit I purchased had a similar bearing issue. Never thought to check it before starting to use it, but it didn't take long, maybe 18" before it started to burn the wood.... I was really off whiteside bits for a long while but with in the last couple of years I have started to buy them again if they have something I need.

I have never had this problem before or after but I do check new bits to make sure they are not defective, like live and learn I guess.
