When it comes to router bits, there are 1/4” and 1/2” shank sizes. What are the pro’s and con’s of each size? Are the 1/2” better in anyway than the 1/4” or vise versa?

The 1/2 shank will vibrate or chatter less at high speeds for a cleaner cut

Only use 1/2 inch shanks in my shop, unless the bit is less than 1/8 inch. Just my rule.

The 1/2” can have a larger max cutter on them. You can use a the 1/4” router bits in a 1/2” router with a split collet. Some real small cutters don’t come with the 1/2” shank, too. It is good to have a 1/2” router so you can use all of them. I really don’t notice any difference in using either of them. You just buy what need to get the job done. I started buying only 1/4” ones because that was all my craftsman router would take.

I have seen router bit extensions but I am really afraid to ever try one. If they are not perfectly concentric you will get some bad vibrations with a bit hanging out that far and spinning at 25,000 RPM. I would not think it is very good for the spindle bearing in the router either. I have never had a job that would need a bit sticking our farther than they normally do.

Cheers, Jim

Some nimble small routers only take 1/4” shanks and for
that they are useful. For handheld use a lighter,
more compact router is nice to work with if the
cuts aren’t too heavy. For router table work 1/2” shanks
are going to perform better.

Like any tool, both very useful for different projects. I use the 1/4” shafts with my compact router for doing signs, edging and small projects. I use the 1/2” shanks for heavy duty jobs. For instance the oak poker table I consider to heavy of job for small router tools. I am also lazy. I have 5 routers set up so that I have minimal time changing bits.

1/4” breaks easier. The only 1/2” bits I’ve ever broken were those they to taper to 1/4” or less near the cutter end, but I’ve broken 1/4” bits right at the shank.

I notice longer life on 1/2” which I think is due to heat.

The half inch bits ,are definitely better and I use them whenever I can. I still have an old router that only takes 1/4” shank bits and for that reason I still keep a few 1/4” bits around.

my bosch colt router only takes 1/4” my hitatchi 3 1/4” hp only takes 1/2” my craftsman will take both sizes so i guess it really depends on what I’m trying to do.

I’ve started using Whiteside 1/2” bits. From my recent experience I’ve got no complaints. The 1/4” bits I’ve used (Not Whiteside) I’ve had to keep a good eye on my work, not too fast, not too slow, no more than 1/8” cut for each pass of the router. Smaller bit, more care is needed in my experience. Just an observation.
