Just one user review on router bits in general.

Most bits are fine it's the way you use the bit (tool) , feed rate to slow or to fast taking to big of a cut (bite) it's true not all routers bits are not the same or to say made the same way.
Cutting MDF,Plywood,other man made lumber can be hard on the bits because of the glue and resin they use to make the lumber.
That said, if you feed the stock to slow it will heat the glue up and stick to the bit and the same thing is true when you take a deep cut you're asking the bit to work harder and the heat will kill the bit.

Many things come into play when using a router and the router bits, feed rate,type of wood, how deep it needs to be, how the wood grain running,what kind of job you want to end up with.

It's alway best to make two cuts with the bit but we all just want to get the job done and we all think what the heck the bit should do it on one pass.
I do it also but if I want a great job I use one ruff cut and then one more to clean it up, this way you will come out with and nice clean and smooth cut and your bits will last longer even the cheap ones.

In conclusion the shallow the cut the better the cut.
I try and use this rule when using router bits.
1/4" bit 3/8" deep cut on the 1st pass, 1/2" bit 5/8" deep on the 1st pass,round over bit and alike 1/2 on the 1st. pass and then one more to clean it up.

BUT if I want a great cut I will make one pass about 1/16" deep and then 2 more, this way it will give you a nice clean edge and I alway try and use push block or a chip breaker to help with rip out error.

Once it's cut that's you can't put it back on so to speak.

Again just one user way to use the router bits and not to abuse them.

I have used Sears bits for many years, but I prefer MLCS bits for the free shipping and the bits are lasting a long time. I use Rockler bit cleaner when they get gummy.

Gary, cleaning the pitch off your bits does make a big difference. It reduces burning and sticking, even helps prevent tear out. Excellent point.

Please teach me.

1) 3/8" spiral-fluted up cutting straight bit (solid carbide)
If I do mainly table-router-working, is spiral bit so important one ?
Bacause it is an expensive, I wonder I can get a big advantage if I buy one.
2)1/2" dovetail bit, 10 degree
Why do they choose 10 degree Dovetail bit the most valueable ?

challagan

Benny, the spiral bit is more expensive due to it's grinding which is why you want one as they are very smooth cutting bits and a up cutting bit brings the chips up out of the cut. For things like a box joint jig... the difference really is big between the joints cut with the spiral and a straight cutter. Tear out is minimized greatly and just overall a great cut. Also great for splinter free grooves, mortices and the like. They are worth the money.. especially a 1/8, 1/4 and 3/8 inch ones or at least in my shop.
On the dove tail bit... 1/2 10 degrees is kind of the standard dovetail size I guess. Many of the machines use a 1/2 inch 10 degree bit and plans often call for it. Others may want to chime in here!

The 1/2" 10 degrees and 8 deg. dovetail bits are made for 5/8 to 1" stock, if you want to put in thru dovetails and go all the way ,,, the 14 deg. dovetail it just to much ....the edges want to snap off.....real easy .....on the 14deg. tails

My choice

Corey san, Bj san, thank you very much.

My choice is(choices are ?) as the first...

1) 3/8 spiral up cut
2) 1-3/8 rabett / cutting length:1/2
3) 1/2 10-degree dovetail
4) 3/8 roundover / cutting length:1-1/4
5) 3/8 cove / cutting length:1-1/4
6) 45-degree chamfer / cutting length:1-1/16
7) 1/2 flash trim / cutting length:2

I would like to have advices.


A price in Japan is high. For example, "spirai" is 7800 yen(more than $60).
If I will buy them at one time, it is better for me to buy them by mail-order to US.
So.. I will.

Joe I got some of my bits from www.woodline.com Bought the 66 pc set haven't had a problem with them. If you want to get fancy though Grizzly has molding sets that I bought from there and they are really nice. Grizzly like Bj says is the other place where I get my bits. Give both these places a look.

Benny, Chances are very high that as a new router user you will damage some bits, it happens. It is good to buy inexpensive bits to learn with. Experienced woodworkers benefit from inexpensive bits since they can buy more profiles, and used carefully will provide good value for the money. The top quality bits like Whiteside brand, CMT or Amana will cut better, last longer and can be resharpened more times. As you replace bits you can buy these higher quality bits. This lets you get started for low cost and then spend money as needed for top quality, a smart way to work.
