Favorite Bits

Thought it would be a good idea to start a topic about your favorite bits, what you use them for and where to get them. I use my X-carve for carving mostly foam and some wood. Like this workshop sign I did for my first project LINK.

I was looking for a good spoilboard bit without the crazy costs out there. After searching google for a bit I found this bit that was 1/4in shank (you need to upgrade your collet as I did for the basic spindle.) 3/4 straight bit w/ a unique plunge blade (unique to me anyway :smile:). It showed up today and I am so impressed with it I wanted to share (Especially since it only cost me like $12) Anyway pics and video to follow. Here is the LINK to the bit,I went with #5455. I think i’m going to try some more of their bits in the future.

Please share your bit knowledge as well, as a newbie it’s easy to get sucked into the higher price bits with little knowledge.

I’ve been looking for something like this for a LONG time. Thanks for the link. I used a .25" flat end mill to flatten my latest spoil board and it took a couple hours. I ordered most of my bits from: http://www.precisebits.com/applications/pcbtools.htm

But these forums are filled with links to Ebay sites with great deals. I’ve learned a ton just poking around.

Yeah I had the same issue with time that’s why I went with the 3/4" bit. Just remember if you’re using Easel to change the bit size to .75 not .25 . Thanks for the link, i’ll check it out. PS. my only issue when buying from ebay is most come from overseas and i’m too impatient to wait :smile:

Also, it works great with Easel’s roughing/detail feature

What a coincidence, while I’m reading your post I was surface cleaning with similar bit my favorite, This one have two different sizes, 1/2" and 3/4" flat bottom. Cleaning surfaces with no waiting time. But of course what you found is less expensive good bargain. I paid $19.99 for 3/4" $17.99 for 1/2" from Sears. I haven’t use them to make hole but I believe what you found have center blade which makes better cut. I’ll order one today.
Thanks for the tip.

Nice! I picked up a 1/4" collet as well but haven’t used it yet. I should invest in a spoilboard cutter; they’re hard to find in the 1/4" shank size so thanks for that link.

My three go-to bits are (all with a 1/8" shank):

1/8" two flute endmill

45 Degree V-Bit

And the 1/16" endmill, which I use in conjunction with the v-bit

I buy most of my bits from drillman1 on ebay.

He’s based in Texas and ships from there. I get bits in 2-3 days.

I also ordered from Drillman1 - probably based in your recommendation. He sells the good stuff at affordable prices and shipped quickly.

Yep, all my eBay links above are from drillman1, he’s only like 30 minutes north of me, I really should try to pay him a visit sometime, save on some shipping :smile:

I find these guys good and free shipping for those in the US, just saying.

Not just upcut and down cut bits also do a range of other router bits. Personally find it cheaper to buy from them than to buy locally in New Zealand, but that’s typical.

OH GOD THANK YOU for this. I have broken all of my 1/16" bits and inventables is of course sold out of them. I just ordered a bunch of stuff from him.

ordered one of each…few questions from a total noob:

  1. on the bits from drillman. do I leave that little piece of plastic on? I guess thats a max dept as well as a way to identify the bit size.
  2. I haven’t tried yet… but it looks like I won’t have the dept to get through a full piece of 3/4" pine with 1/8 endmills that I ordered. Are the ones form Inventables longer?

Go to Enco. http://www.use-enco.com/CGI/INSRHM They have end mills with different length of cuts .

Does anyone have a source for 1/8" end mills that are compression cut?

Does anyone know of a thread showing the uses for different style bits? I know there are multiple uses for certain bits but it seems they all have their specific job they excel at. ie; ball, upcut, downcut ,4 flute, 2 flute etc…? I also have had good luck with drillman on ebay as well.

Here is a primer: https://buildyourcnc.com/endmills.aspx

Yeah, I don’t think you can remove the collars. I’ll have to measure tonight (although you probably have yours already), but they may be just barely long enough to get through 3/4" material.

The ones from drillman measure on average about .623 from the plastic to the tip, so unfortunately, no it won’t go all the way through 3/4" stock. I ran into that yesterday doing some test cuts.

seeing the same on my end… I was going to get a pic of how short my mil is.

They are still awesome bits, I was making some great cuts into Walnut the other day, but I’m also wanting to go all the way through some 3/4" material pretty soon here.

Anyone have any amazon (for prime shipping) sources for 1/8 shank endmils that will cut through 3/4?

Not quite your amazon answer, but my 1/8 fishtail bits from drillman1 came without the plastic and are longer than the bits in the starter kit. I think it may all just depend on what you buy.

Here is another one for 1/8" spiral compression from amazon. Not so many choices for 1/8, that’s why I purchased 1/4 Colette from Inventables for 24VDC stock spindle. Unfortunately not using that colette anymore after upgraded to Dewalt.
