The O-Flute is a favorite in the sign-making industry. This bit is extremely good for plastics and ejecting chips efficiently as possible from the CNC workpiece. This O-Flute bit is known for cutting Aluminum, Plastics, and Foam boards. This needs to be your CNC router bit of choice for soft and hard plastics.

Our pleasure!

Thanks so much for the great video. I’ve noticed that you give so much information and you’re a good teacher. I’ve learned more from your videos than any other resource (I currently have) on the “Do’s and Don’ts” of CNC Machining. Your Chip Load chart and excel spreadsheet helps me every day at work where we have 2 different industrial CNCs. We often run 2 spindles with dual 12 tool auto changers. So seeing your large CNCs it sucked me right in because that’s basically what I run every day. The 1 Anderson CNC we have also has a moving table @ 10’ X 5’. Thanks for all of your hard work making videos and sharing information.

[@nrayanerhg53h]

Very well explained and to the point. Thanks!

[@pantalalabs]

You saved my day. I was cutting PSAI (softer than acrylic) with a 2 parallel bit and it melts every time. Changed for 1 cut flute, slowed down spindle speed and 1/2 of the feed. Now I have a clean cut!!!

[@honestreview1611]

Makes complete sense. I was once cutting some nylon with a .062 4 flute bit and was completely wrong bit for what I was doing I was going through so many it was crazy. Live and learn! Thank you for the good content!

[@skyhawk1256]

Hi Ryan, a really great video serie you have made here,thanks...

[@ncallas53]

Good information, thank you!

[@Joeyarhino1]

This was a great video I’m gonna buy a fixed base router to cut some plastic and this was very helpful

[@ChipPuccio]

what method other than clamps, or screwed down will work in holding sheets to the spoilboard? Will be working with .25 and .5' thibick 4x4 sheets and carving out 10x8 rectangular and 3x6 oval signs out of sheet and do not want to use tabs . double sided tape or CA/Blue tape work in securing well?

[@ronaldramsey7774]

HELPED ME A LOT...THANKS FOR THE INFO!

[@Cico9189]

Great video. Subscribed. Thanks brother 👊✌️

[@acerjuglans383]

I have an Amana O-flute downcut bit. I bought it to use when cutting acrylic sheets, for my LED signs, but I haven't gotten around to trying it yet. Just an FYI there that there ARE downcut versions of an O-flute out there.

[@cutting-it-close]

There is but I don’t understand why, it gums up and melts your material instantly.

[@nizamuqureshi5818]

Thank you 😊 for your information

[@BeaulieuTodd]

Super helpful!

[@jeffverdin6105]

Good video! Thanks again

[@shelby50411]

Very nice but issue is o flute bits are extremely expensive about 10x cost of 1 or 2 flute...i have had good success in king color core hdpe using single flute

[@GarrettFromme]

Good explanation. Thank you

[@botoepfer8588]

Hi I cut and mill HDPE with O flutes with no problem I started to "Trace " or "engrave" using a 30degree chamfer bit and it do not get clean images. what bit do you suggest, The depth of trace is -0.0638 to -0.0955. Thanks

[@evanlane1690]

Thanks!

[@MartinsonManufacturing]

Thanks man!

[@anthonydellinger3016]

Great Video! Thank you... What bits have you used for Engraving/Pocketing into 1/8" Two Color plastics for letter heights 1/4" to 1"? Keep the videos coming, your doing an awesome job!!!!!

[@PanayiotisMavrokefalos]

Very informative and to the point video Ryan! Thanks for sharing. Sheds some light on how to start cutting plastics. What about the performance of the machine. What are the minimum feedrates and rpms are required for this bit to perform? Also any ideas how to handle plexiglass? I need to cut a small piece but have no idea what needs to be used.

[@PanayiotisMavrokefalos]

@@cutting-it-close super thank you!

[@LG-ro5le]

What is the best way to probe a spiral o flute end mill? Ive found when i use a touch probe it always completely misses the material surface on the first pass, and when i use the manual Z - 0 position technique with a piece of paper it always ends up cutting too deep

[@krasimirkolev777]

Thank you!

[@slingernoob356]

What plastic are you using in the video at 3:02. And what website did you buy it from. Thanks!

[@hesperaux]

Excellent. Many thanks. Liked, and I think I'm going to sub.

[@philstat100]

Thank You for the great video and very valuable information. If I undrstand you correctly I could use this bit with my plunge router to make a circle. Please correct me if I am wrong. again Thank You.

[@giostourista]

can you please tell me what kind of bit do i need to make a 3d on acrylic? i tried tapered and ball noses..but nothing works.. they leave stuck material on acrylic..

[@cutting-it-close]

Your RPMs are too fast! Or feedrate too slow, it’s melting the acrylic

[@buddyturner]

Good video, what bit and speeds is best for engraving cast plexiglass? I am getting build up on vbits and carving or engraving bits that mar the surface. Thanks

[@cutting-it-close]

I would slow down the RPMs on that, you are melting it I think.

[@raybrown919]

You need better microphones to sound quality goes loud or quiet, loud or quiet and it’s hard to listen to you with headphones on at the loud parts are really loud

[@Nunak91]

Single flute and O-flute are the same thing?

[@FMR_FMR]

Too many thanks

[@DREAMVIZON8]

Great Video!!!! what's the name of that material you was cutting on the CNC machine thanx in advance

[@cutting-it-close]

HDPE High Density Poly Ethelene I believe is the correct spelling

[@Sam-ch4jh]

Thank you I struggled with a hand router cutting plastic (nylon 66) using straight end mill Will try this, is there any other name, could not find in aliexpress

[@wd9102]

Take a look here www.aliexpress.com/premium/1-flut-aluminum-mill-bits.html?d=y&origin=y&catId=0&initiative_id=SB_20210101205142&SearchText=1%20flut%20aluminum%20mill%20bits

[@chrissewell1608]

Did you try an American company?

[@forloop7713]

Can I use these to cut wood

[@CrazeUK]

Good video. I wonder if you can get small ones of these.

[@stevenalexander4372]

Yes you can. I've used 1/8" but I believe they make smaller.

[@sebastiandelamaza8440]

you can be more agressive with your stepdown, i use a Ø6mm endmill and cut 30mm HDPE in 2 passes

[@mattbowers5342]

Hadn’t heard of this type of bit, so appreciate the info. It looked like you were able to feed this bit pretty quickly in the clip with the red plastic, what type of material was that and do you know what the federate was there?

[@mattbowers5342]

Cuttin' It Close thank you for the response!

[@matt10cool]

Can you use o flute bits for hardwood?

[@jasoncross5684]

Where you gone you’ve disappeared

[@jasoncross5684]

Really pleased hope you haven’t been badly affected by the lockdown

[@chrissewell1608]

The O flute bit, looks like a broken drill bit!
