Why Are You Still Using Amana Bits?

This is a direct comparison for the Downtown Jenny bit by Cadence Manufacturing and Design VS. Amana 46415-K downcut (downshear) .25" CNC bits! The Downtown Jenny is now the Amana Killer in my shop
I used my Onefinity Journeyman CNC to do these cuts and compare them in walnut for my trays. This test is to find out which of these bits will last the longest for me and what I do in my shop. Hopefully this information will be helpful to others as they work on their own CNC projects.

[@rileyjenk]

Purchased the Jenny bit. Thing is amazing. Thanks for the info!

[@ianconnor3937]

I thought bits would last much longer in general (than your 40 trays). Now I know what to look out for in terms of bit wear. And now have a good option for a workhorse bit with a discount to boot. Great video.

[@alexanderdgray]

Did a couple jobs on oak this weekend, and my ShapeOko 201 quarter inch end mill was leaving major fuzzies behind. Cadence came up on my internet stream not long ago, and your video (and discount code) sealed the deal. Can't wait to try it out.

[@Vintauri]

Nice review of the two options. I’ve also been switching over from Amana to Cody’s bits as I go through mine. While I have not done a repetitive test like you have here, I’ve noticed super clean cuts and less cost on my work. Plus I love supporting a small family business!

[@HamiltonDilbeck]

Yep, huge wins all around!

[@ClintonCaraway-CNC]

Carbide should stay sharp much much longer than what it takes to make forty of those trays. You need to check your feed rate and the rpms of the spindle. Heat is the enemy of tooling. If your chipload is correct the heat will be carried away in the chips.

[@particleconfig.8935]

did that... help (a lot)?

[@geekers3005]

All wood contains silica (think sand). The silica is why wood wears the bits. Too slow a feed rate or to fast of rpm results in more cuts for the same amount of wood removed. In my experience, my bits are always cool enough to touch seconds after finishing a cut. Hence, not very hot. Not hot enough to impact wear resistance.

[@WindRidgeWoodCrafts]

Nice, simple comparison. Thanks for taking the time to share the results. While I've been buying Amana bits for the last three years for my CNC, it's not lost on me that Cody is regularly in the CNC groups offering help for any number of topics, where I've never seen anyone from Amana, nor would I expect to. I'll be migrating to Cody's bits as my corresponding Amana bits wear out.

[@HamiltonDilbeck]

Thanks for the commment! And yeah it certainly seems like he's very invested in the community and making things user friendly. From what I've seen he has been expanding his library of bits, so I hope that he doesn't stop!

[@alterstassfurter5743]

I'd like to see the prices of the Tools to be able to compare Performance and price...regard from good old germany

[@dtrip07]

Always appreciate the videos!. I ordered my journeyman about 8 weeks ago. Your page has been super helpful for me as a first time CNC owner with little to no background in CNC. Thanks again!

[@HamiltonDilbeck]

Thanks for the comment!

[@JF32304]

I'm getting my other 2 shipments today! I'm stoked! I got 1 of the "Y" rails yesterday and it's incredibly stout.

[@MattWhit1975]

Nice job with the comparison video. I appreciate that it didn’t go into a bunch of technical detail that would have been over my head. Just a simple test with easy to see results. I’ve got a a couple more of each of Cody’s bits. In fact, the postman dropped off a pair of the new Slim Jens as I was watching this video. It’s nice to support small businesses.

[@HamiltonDilbeck]

Thanks! And thats funny about the Slim Jens lol!

[@brentovercash9018]

Thanks man... An Amana user that just ordered a bunch of these!

[@laynemimstx]

I do a lot of cody's bits. other day doing cutout of poplar, and me being lazy, i just grabbed my downtown jenny. used spiral ramp and it cut as well as any every. no marks, no sanding needed. it is an amazing bit. thanks for the great video showing that.

[@HamiltonDilbeck]

Yep they rock!

[@cnccarving]

it was a true test and surprize the bit you tested brought better result than the praised brand bit i checking now where these bits can be purchased thank you for your video

[@jnick67a]

Cody is awesome. I have been a customer for a while now. Can't wait to see what he comes up with next.

[@southernjoes8372]

Jenny bits are definitely my favorite. The down cut v-bit gets a workout daily

[@goodwinml]

Great video. I have a pair of each of the Jenny bits. I Love them. Cody did an awesome with The Jenny's!!!!

[@ajfinewoodworks3050]

Very informative, a well done video. One thing I noticed is where you said you had chatter on the wall, it looks like that was just where the bit stopped its x-y travel to plunge to its z mark. Other than that, I'm always on the lookout for cheaper, better bits. I've always been questioning the Amana coatings or the Bits and Bits coatings. Seems like some of that is just hype. I used Bits and Bits Astra coated 1/8" compression bits for cutouts on birch ply, and didn't get any better results than with the cheap uncoated bits from Amazon. Keep up the great work!

[@5280Woodworking]

Interesting video. I do wonder what your chiploads are. I feel Cody is a bit too conservative and I know Amana is. Amana specs 0.005 for “wood” which is laughably low…like they are trying to dull your bit faster. Heat is a bit killer and IMHO you should be getting more than 40 trays out of these bits. I plan to do this same test on my ShopSabre soon.

[@steveowens7136]

Nice comparison! Thanks Hamilton

[@HamiltonDilbeck]

Thanks!

[@barrypolis6720]

I've been using Cody's Jenny bits since he released the first original Jenny, on my Onefinity... I haven't found anything to compete... I do own a few bits 'n bits, and Amanas for specialized cutting. But, head on for compression, in both 1/4 and 1/8, the Jenny prevails. Also have the skinny Jenny TBN, and will be ordering the slim 1/8 and downtown... Thanks for the clarity of comparison... Just noticed you're right down 20, in Cumming, so thanks for the comparison vid, neighbor...

[@HamiltonDilbeck]

Nice! Small world!

[@ronnorris1504]

I do love Cody's bits and never tried Amanda but because Cody is a fellow cancer, i really like the communication with him. Really good video and prompt for Jenny bits. Thanks! Look forward to your videos

[@HamiltonDilbeck]

Thanks!

[@th3fallen]

I’d be curious how spetool holds up, I’ve been running them for months and they seem great

[@Agriking]

Nice review. Simple and to the point.

[@HamiltonDilbeck]

Much thanks!

[@joelholland6982]

Good afternoon my name is Joel, I have a question for you. Do you have a video on your sandblasting techniques for after carving Wood?

[@robbie6625]

You might take a look at Nyalox brushes for cleaning up the fuzzies. They work wonders for me

[@jimmyparksproduction]

Been using the Jenny Bit for about a year. Not only do they last longer you can also cut deeper and faster than the other bits. Its saved me from buying another CNC machine. For now anyway 😂

[@HamiltonDilbeck]

hah! nice

[@colencasey7761]

have all the jenny's and love them

[@HamiltonDilbeck]

Nice!

[@ReeseCustoms]

The part number alone is enought to make me buy it. lol, well, and better performance at a better price doesn't hurt either.

[@mlibby05]

That's not chatter on the walls, those are dwell marks. They are aligned with where your Z axis has to raise or lower.

[@theohiowoodshop238]

Ordered! Thank you

[@HamiltonDilbeck]

Awesome!

[@InTheLab3d]

I think I was the recipient of the first ever jenny bit, and even then it was perfect.. Im still using it... The only time I use any other bit is if Cody doesnt make one for the job I need.

[@HamiltonDilbeck]

Thats pretty cool!

[@ChtoDelaetMaks]

Wow! These trays look amazing! I have never seen trays with such relief before. I've only come across flat bottoms. Is it difficult to clean such trays from food debris?

[@shaunm2208]

Thanks for this as I’m a real beginner, I wanted to ask what software you use for design please

[@TerrapinCreations666]

Very cool video. What are those trays for? Just curious!

[@proactivex]

Do walnut trays like that warp over time or stay perfectly flat?

[@danmcknight963]

Great video, thanks for the comparison. Will order Jenny's the next time I need bits. Any chance you are going to do a video on the design of those trays? I love the way they look but don't have a clue where to start designing one.

[@HamiltonDilbeck]

I might in the future!

[@victorunderberg6615]

Awesome thanks for sharing.. I have often thought of sandblasting what do you use for the sandblasting of wood have done a lot of steel but I've always been too afraid to try it on wood especially something that I do in 3D

[@reedsmith5105]

Do you have anything showing your sandblasting setup? I'm very curious about this aspect. By your recommendation, I purchased a couple DTJs a few months back and am very happy with them. Cheers!

[@tonywright4361]

Check your side pressure if you can as the fraying is at the same spot on both bits adn bowls . This would indicate that the Metal in the Amana is softer metal and has more flex than the jenny.

[@HamiltonDilbeck]

Great info, thanks!

[@samo4866]

$5 cheaper and it lasts slightly longer? That is an amazing deal over the long term. Now, can it be sharpened reliably? I can get mine sharpened with the new dimensions for a decent price locally, and they specifically say they sharpen all the major brands, so if it can be sharpened, it might be extremely worth it.

[@kelleysislander]

Hi, Thanks for the information on the end mill - I went and ordered a Downtown Jenny after seeing this! I also work with topographic subjects on the CNC, and I was admiring your trays that have the contour lines. How did you create the vectors? I am imagining that each contour was on its own layer and you assigned its depth of cut based on the particular contour?

[@johnhall2806]

Thanks for the video. I have a question a little off subject. I use the same double stick tape and Downtown Jenny bit you are using. My question. What do you do to keep the bit from gumming up from the tape on through cuts? How do you clean them?

[@zoltanbereczki8067]

What are these trays good for actually? You serve something on them because i wonder how to clean / wash them?

[@Karim_teran]

I run an industrialk cnc and cut laminate all day. LMT onsrud bits the downcut marathon is a beast I use a 3/8 and 1/4 and the 3/8 lasts 50-70 sheets 5'x10' . and their nmot bad like 40 bucks from ballensaw.

[@OnefinityCNC]

Great video!

[@HamiltonDilbeck]

Thanks!

[@misohlavati]

Dude nice comparison. How much did it take you to make one of those topo trays?

[@user-tn7ew2fx1d]

I've never heard of sandblasting the part. I like the idea. Can you give me some info on that? What media? Are you using something like a small harbor freight blaster? Thx!

[@HamiltonDilbeck]

Just KZbin "Hamilton Dilbeck sandblasting" and I talk all about it!

[@user-tn7ew2fx1d]

@@HamiltonDilbeck Cool, thx!

[@tfwoodcraft]

do you sell those trays? didn't see them in the etsy shop and they're so cool!

[@marshallharrington4727]

What are the trays for. Sorry if its obvious

[@JohnColgan.]

Are you getting any gumming on the cut face with repeated cuts? Specially if allowed to cool and go hard. For the amount ofwork you're making those bits do, is an upcut better? downcut is back scraping the woood fibres, probably your cause of sidewall chatter. Straight or upcut would be cleaner. New HOGGING bit much better still!

[@scottwalker9727]

I just ordered 4 Jenny bits but have been sick and have not used them yet. Thank you for this video as I have a lot of Amanda bits and would be nice to save $. What sandblaster set up do you use? I do a good amount of 3d and looking for better sanding options.

I can get Amana bits faster and at my local woodcraft, once his distribution and supply gets better I may switch to him. I have a few of his bits and I see no difference in my cuts. the quality is there. I think he should talk to Jonathon Katz Moses to help his distribution

@@HamiltonDilbeck Yeah. I see you only have a few. But those few are that many more than I have from others. Gotta start somewhere. I’m just finishing up my shop. Just got my Onefinity all together last week. Dialing it in. Coming along good. I also have lasers and other stuff. Trying to get my skill level to resemble my equipment. But that’s another story. Want to start a KZbin channel too….but….only so many hours in a day! But you’re doing good. Keep it up.

[@HamiltonDilbeck]

@@whitecollarworkshop NIce! Hopefully lasers are in the cards for me at some point! Yeah with KZbin- I kept telling myself every year for like 5 years that I would start and every year I wished that I would have started the year before lol. Finally just jumped in .

yep! Just search "Hamilton Dilbeck Sandblasting"

[@Dave-ni4vg]

Where do you get cnc tray files from

[@HamiltonDilbeck]

I make them

[@irishful1]

why do you buy bits with so long flutes? you only use the tip anyway but pay for the whole flute length.

[@HamiltonDilbeck]

mainly laziness- I do a lot of profile work in 4/4 and 6/4, so its peace of mind with the cutting. Everyone is different, I guess!

[@particleconfig.8935]

it didn't ''come off'' (because you pushed it)? lol o_

[@JayBergCustoms]

Holy smokes, I am obviously using my bits for wayyyy to long 😲

[@HamiltonDilbeck]

Lol, you're probably fine. My trays are hard on them and 40 trays is over 20 hours on each of them! Not to mention they are plowing through double sided tape on the profiles.

[@JayBergCustoms]

@@HamiltonDilbeck yeah, I'm definitely not doing the fine detail stuff you do in those trays. I did just lose a Whiteside astra coated 1/4" downcut spiral bit while carving the center panel out of some kitchen cabinets for a neighbor (remodeling with glass). The nice people who made her doors used about a dozen brad nails to secure the panel for some reason - shot in from the side? Weird, weird, weird.

[@HamiltonDilbeck]
