You've been extremely helpful to me, young man. I really appreciate your vids.

Excellent 👌 thank you The note about coming down at an angle really helped

I really like your detailed videos. How about one on climb cutting verses conventional cutting.

Another informative video. One other way of determining between upcut and downcut bits is to carefully feel where the cutting edge is if it is on top of spiral its upcut - on bottom then downcut. Please keep the video’s coming. If you’re looking for ideas, best ways/techniques to hold material down for cutting/milling - including examples of how to make one’s own hold downs. With your experience I bet you’ve tried a few different methods and may have a favorite or two. Many people can’t afford a vacuum table.

Was just researching this last night! It seemed like in the cnc world compression bits may be the way to go, but your explanation on using the spoilboard is a great point I hadn’t considered.

I Have been using a CNC for about a year now (as a hobby) and I already understood the uses and practicality of the upcut vs the downcut bits. But, I really like your presentation and your explanation of this information. Also, I have only worked with wood and the information you presented kind of triggered me to consider maybe trying some aluminum and maybe some acrylic as well. Good Job!!!

I was always worried about cutting 1” or 3/4” material with down cut bits. I’m gonna give it a try. I always thought they were for thin material. Thanks for the video!

i just cut 3/4 plywood first time down cut bit and has lot lot better than all my up cut bits, all my plywood work i use now first down cut and then change bit cut deep up cut bit, little more work tool change make but ready plywood not need prepare anythink after work. only up cut i used before and has horriple big job clean plywood top side after work.

I built my own CNC (powered by a dremel) during lockdown and while it´s not that strong it was dirt cheap for me to build and it´s good enough for small wood projects and surprisingly precise. Your videos really help me along but contrary to what you said i made quite good experiences with 1/8" straight cut end mills and they are pretty much my go to end mill for most stuff because they leave such clean cuts. I guess the effect you´re describing is that the cutter probably bounces off the wood more or is it just harder on the spindle? I guess I´ll have to test around some more... Greetings and a big thank you from Germany!

another great video learned something again i run my wood projects at 16,000 with a 2.2 kw liquid cooled spindle and do lots of test cuts with pine witch is stringy any advice.

thanks this help me lot, i think best way cut first groove down at plywood and then change bit and deep need cut up. i use lot 3/4 or biggest plywood make groove or cut plywood shorten piece. and outside piece off at plywood. just order some down bit and need test, up cut has horriple work clean after cutting. i order some traight cut bit too, how this and were this used ? i think maybe clean side corners etc. i not has work lot whit my new DIY cnc machine yet but learn what id better bit use and were can use different bits.

Thank you for sharing great video 👍👍👍 what type of bit would you recommend to cut 1/8” plywood on a cnc router? And where can I get them? Thanks

@PanayiotisMavrokefalos 3 жыл бұрын

Useful info. Time to experiment with some down cuts. Sounds like if you wanna cut it close and clean you gotta cut it downwards :D

@LDBecker 3 жыл бұрын

Good point on using compression bits on smaller CNC machines. On my Laguna IQ Pro, they actually work well - even though it's more of a hobiest machine. It handles what I need to throw at it. Using downcut bits can be a problem also if you're compressing chips into the cut line on thick hardwoods. Potential fire hazard, I would think.

@LDBecker 3 жыл бұрын

@@cutting-it-close I've had chips packed so tightly in the cut line that it worried me, and they were warm. Maybe if the speed you're cutting at is high enough it wouldn't be a problem. My machine is a bit limited there. I've also taken to doing a final cleanup pass on cuts - makes the edges nicer, but takes a little bit longer. Thanks for the videos!

@shaynesabala 10 ай бұрын

Thanks so much. Great detail but I still have questions lol. First, what did you mean by a ramp? Second, if you make a pass with either bit and vacuum the groove, does that alleviate the problem of chip build up?

@JimsRobot 3 жыл бұрын

Great video, best I've seen on the subject. At a guess what bit would you start with to cut lightweight 16mm falcatta ply with gloss laminate on one side and matt laminate on the other? Advice without responsibility gratefully accepted 👍

@tadge74 3 жыл бұрын

Could use a down cut for 1st pass and up cut for 2nd pass of doing 2 passes. Cheaper bits than compression

@LagMasterSam 3 жыл бұрын

My first thought on telling the difference is which side the sharp edge is on (top of bottom). The up-cut has the sharp edge on the top of the spiral and the down-cut has the sharp edge on the bottom of the spiral.

@davidthompson9359 3 жыл бұрын

I just spotted this, but what I also see is the up-cut bit looking from the tip spirals clockwise and the down-cut bit spirals counter clockwise.

So what you are saying is that uncut always sends the chips toward the router motor.

@TheAwesomeSam 3 жыл бұрын

what if i want to cut deeper than an inch and a half or 2 inches in wood? is there a bit long enough for that? or is that not safe to do on a cnc machine? thanks!

what have been easier to explain it while you just did two cuts one with a down cut one with a up cut in a closeup video and maybe a slow-mo.

My feathers are ruffled. I can't wrap my head around a downcut being better for pocketing.

@vladiocy2884 3 жыл бұрын

Much better. Just talk more slowly. Delamination is the word. Tears and flakes. 2 forces, axial and radial. Not only recut chips but most, the heat. Is the number one enemy for end mills. Shearing angle. That is what you was mean about the spiral and the straigt flute?
