The Bits I Use In My CNC Machine

[@tekgrrl]

Really great content Chris, thanks for sharing your knowledge and equipment!

[@fredygump5578]

Thanks. I'm researching what bits/ how many different kinds of bits I will need for my new CNC, so this video was very helpful.

[@HighlineGuitars]

Glad it was helpful!

Thanks Chris . . . This has addressed questions I have had for some time . . . . . love that .023" spiral upcut . . . great job

[@thedirtyknobs]

can you touch off with the .023 or do you set it by using a piece of paper and manual set z?

[@chadwooddesigns]

Chris you are always my goto luthier ! You are awesome!

Really helpful info. Greatly appreciate it!

What rpm/ speed do you set your trim router to for cutting out the guitar body?

[@HighlineGuitars]

Speed setting 4 which is about 22,600rpm.

Thanks!!!

[@SkyscraperGuitars]

Great info

That .024 fret bit link is no longer valid on eBay. Can you tell me the number of flutes and the cutting depth of your cutter? I'm cutting for jumbo frets with a .070 tang and I don't want to go too short or too long (and have it break)on the cutting length. What are you using? Thank you.

[@AMusicalPsychosis]

Any particular reason for 2 flute vs 3 or more?

[@karkjones]

I am just starting out on the CNC and would like to start cutting out a telecaster body to start since it would be the most simple. What bits would i need for just a tele body?

[@HighlineGuitars]

You don’t select bits by guitar type. You select them based on the type of machining operations that you will need to perform. And what those operations will be depends on how much of the work you want to do with CNC and how much you want to do with other tools such as a drill press and/or a bandsaw, etc.

[@karkjones]

@@HighlineGuitars thanks for the reply. i'm looking to do most of the heavy lifting on the CNC. So i wanted a long enough bit to profile the outside to get through 1 1/2 - 2 inches. and bits for the pickup pockets and the string holes. Very new to CNC and guitar building so appreciate any help. Trying to teach myself on a 4 x 4 Xcarve using Vcarve and easel

Hey Chris, the 1/4 bit you linked to for cutting all the way through bodies is only a 1.5" length of cut. For thicker bodies, do you not need something like 2" length of cut? I guess I'm kinda confused about how much the loc actually matters.

[@HighlineGuitars]

The length of cut only needs to be equal to (or slightly more than) the depth of cut. I guarantee your doc isn’t going to be 2.” More like .06” to .25” depending on the strength of your machine and the power of your spindle. To cut through a blank thicker than 1.5,” you need to look at overall length, not length of cut.

[@MarkGutierrez]

Hi, the 4" bit has a 1.50 length of cut. For a body that is 1.75" is it okay for the shaft of the bit to make contact with the wood? How do you reconcile cutting contours of bodies thicker than 1.5"?

[@HighlineGuitars]

I’ve never had any issues making cuts deeper than the length of cut.

[@drummondF]

I'm curious about those collars on the 1/8" bits -- what are those called?

[@stickstickly13]

Hey Chris, thanks for this great information. Just FYI it seems like your first Amazon link may be incorrect. It is taking me to the same down cut bit as the second link. Also, how long is your long reach 1/4 bit? The video makes it look like it may be longer than 3 inches. I've been searching for an ideal bit for getting all the way through a guitar body, so I'm especially interested in this one. Thanks!

[@HighlineGuitars]

I fixed the link for the upcut bit and the long reach to the 4" bit I use. THANKS!!

[@artgehr7178]

Very good info. I am waiting for the followup with your feeds and speeds. You should check out Precisebits.com. They have 1/8", and 1/4" precision collets for the Dewalt 611 router which helps prevent bit breakage.
