I am looking for a ¼" trimmer router bit that has a blade length
over 2" or a bit that has the bush at the top. I have searched the net
but to no avail and so I would be greatfull for any information.
Some time back, I looked for such a bit. Also posted here. Never found
such a bit. The good suggestions from here: Use a shorter bit with the
bearing at the top and make one series of passes for the first 1" using the
template and then do another series of passes for the lower 1" using the
top 1" as the template. HTH.
Start looking here:
You need a 50-138.
That length is not available in 1/4", which would be dangerous.
I assume you are looking for a flush trim bit, you won't get a 2" one with a
1/2 inch shank but you can use the RCT351 available from Busy Bee Tools in
Canada http://www.busybeetools.com/ This one has the bearing at the end
near the router. Lee Valley has flush trim bits with the bearings at the
other end. I use the two with a guide when I need to trim something less
than 2" but more than one inch. I trim once with the bearing on the guide
template with the busy bee bit then flip the piece over and trim with the
lee valley bit now with the bearing riding on the surface just trimmed.
Also busy bee has free shipping on router bits, at least in Canada.
No on-line shop, but you'll find their details on their home page and
their telephone help/order is really top notch. I have a large router
bit collection from them, all first class.
I'd be surprised if you found a 1/4" 2" long bit. Sounds dangerous...
I have a 1/2" shank, 3/4" diam. and 2" long cutting with both top and
bottom bearings trimming bit and have used extensively. Still cuts
like on day one.
There are 3" & 4" solid carbide cutters x 1/4" CD x 1/4 shank; I have
It is understood they are fragile and very operator technique
sensitive. Chip clearance is difficult in deep excavations, and they
break like glass.
There is no bearing that will render this cutter a flush trimmer but
bearings do exist with 1/4" bores. For best results here consider a
