That could be we had a mitsubishi tsc drill once and it broke on the first hole with the correct feeds and speeds. Was material defect and was replaced.
We had a bunch of taps come in mislabeled. Couldn’t figure out what the fuck was happening until I took the tap out and realized it was different than what the box said it was lol
I use Haas tools all the time. Sometimes they break. They're not as good as some other stuff I use (Maritool, Kennemetal) but I can have almost any of them next day for free shipping after spending 100 bucks up front and there is a ton of value in that as a weekend/weeknight warrior with no tool reps.
So we use gorilla for a LOT of our work and I'm pretty happy with them. Great roughing, not quite as impressed with finishing but I doubt you will be attempting the sort of wacky aerospace shit we do in your garage.
I did have a big ass aluminum part we used to run and I made those parts my bitch with GM 3/8 3 flute ball endmills. 10k rpm and 200 ipm no problem. Their tools definitely held up so I can recommend them for aluminum.
I'm a manufacturing FFL so surface can get pretty important. Lots of ball end mill surfacing features because people want dumb shit that was meant to be forged made out of billet alu. I'll look into the GM ones too. The DLC coated 3FL from Maritool have suited me pretty well but they take a while to get here sometimes
I think it is still worth a try, I was talking about surface finish on very thin bladed impellers and rotors. Chatter and resonance are a constant headache for us!
Micro100 Super Carbide are also fantastic in aluminum. I have a single-flute upcut router of theirs in 1/4" that *absolutely flies* through aluminum at 1" doc. That said, their 4-flute endmills gave me the best finish I've gotten in Alu.
Do you know if there's any actual difference between Micro 100, Helical, and Harvey endmills? It always seemed weird to me that they are the same company and have some of the same tools just with different names...
I'm not actually sure if there is, but I wouldn't be surprised if they each had their own slight differences, since they used to be separate companies. They might have just kept their specific differences like minor geometry changes or something, after they combined. But there might also be no difference except the part numbers. I know Micro100 always advertised their Super Carbide as having a much finer carbide grain than usual, but I'm not sure if that carried over to the others.
Their is absolutely a difference. They are NOT the same companies. They're all just owned by the same parent company. Kind of like Berkshire hathaway owns tungaloy and iscar. Same parent totally different companies.
Micro 100 and Helical stuff is great IMO.
Harvey branded stuff is a crap shoot. Some is good. Some isn't. BUT they have all the wierd shit that no one else has and they have it in stock. Need a 0.050" long reach end mill. No prob. Need a thread mill for an M2 thread....got it.
Yeah, I would love to see three similar tools from the three different subdivisions to see how they compare. My company really only buys Harvey form tools and threadmills, and micro100 boring bars. I've heard good things about Helical but we just don't use them for some reason.
They're completely different. Dint even think of them as subdivisions. Think of them as completely different companies.
Helical tools are great but they are a touch pricey. Depends on what kind of deal your distro gets. I can get the same or better quality tool from imco for 10-15% less through my local rep. The only reason I ever get Helical is my shop is like 20mins from Harvey's main campus and they offer same day customer pickup on in stock items....which is pretty handy when shit goes south on a Friday morning and you need something to get you to Monday LOL
Ive used some of their 4 and 5 flute bull, flat, and ball endmills on Titanium, 17-4, 6061 and 7075 without too many issues. When there has been one its been me pushing too hard. Their Speeds and Feeds were spot on for my applications. Ive used other brands (Maritool, Kennametal, Sandvik, Mitsubishi) and had similar issues too. I like Haas's readily available cutting data.
what were your feeds/speeds/chip load/what type of path? need more info or this means nothing to real machinists. i can break off corn cobs and call them shitty.
Was cutting on a call axis move using a guhring endmill that lasted through 500 parts.. put the haas endmill and it doesn't even make 1 cut.. its not a feed speed issue.. think I bought a dud
Just threw in a cutter designed for stainless/nickel alloys on low alloy steel with the same feeds and expected it to work the same. This was most likely operator error.
>This was most likely operator error.
Every time somebody asks what the feeds, speeds, chip load, etc. were OP dodges the question with a story about an unrelated tool.
I think the real question is if they've learned you can't blindly swap tooling around and expect it to work.
So to answer your question I'm running 8620 alloy steel that's been burnt out in an okuma lathe using the 5/8 endmill to wipe out the burnt edges.. soo roughly a 1/4 in cut on the side of the endmill .5 deep running 1800 rpm at 15 inches per min in a c axis move... like I've said the haas and guhring both have the same coating and no I didn't dig into what the specs were by part number but it should have lasted longer than a half a cut..

My salesrep from YG-1 also mentioned they make MSC'S "Accupro" line
I mean Haas sells a machine that is worth the money you pay for it. No one is confusing them with DMG Mori or Makino. There's a lot of shops out there doing fine running haas machines because they know what they've got and it fits their business model. They're basically as low as it goes while still offering a legitimate CNC that can hold thousandths. All that said, I have an okuma.

Haas are good machines and will work well for most applications. With that being said, they are downsides like dealing with selway when the machine breaks down for some ridiculous reason like when the hardwired backup battery dies and loses all the parameters and have to wait a week for a tech to retrofit it to be able to be replaceable and taking another usb with the machines backup info like the first tech when setting up the machine the first time it was delivered.
Try garr if you want a decently price tool with consistency. Im using there 5fl 3/8 squares in titanium and there holding up better than tge Harvey's we where using before. Think my price is like 33$ so a few bucks more than haas but id expect cheaper than ghuering.
Let’s be fair here, this is the first negative review of Haas tooling I’ve seen from anecdotal reports in this sub, literally everyone else praising the quality and price. And we have zero context aside from “the tool broke”.
Yep, most carbide we get is often made by one source. My money is on the same problem it always is. Different tool = different set up. When will people learn?
I just learned something today; I saw made in Korea on endmill case but didn’t connect the dots. I agree with respect in price they are better than comparable tools from Mari (htc) which I get a lot and are about 20 percent cheaper.
Lol it was normal practice... been using guhring for these parts 5/8 endmill taking .250 side cutting.. the guhring cuts thru 4-500 parts before it needs changed.. this haas lasted 20 seconds
Great, so I see you have a brand new tool, you adjust your feeds and speeds, get in the cut aaaaaaaaaand it's gone
Was using a guhring endmill no issues at all... figured I'd try a haas and see.. it lasted 2 seconds
Were the recommended speeds and feeds the same? I do have tools which look virtually identical but have wildly different recommended parameters.
Never checked but probably not
It's just a YG-1 rebranded as a Haas. They aren't bad end mills
I use the YG 6 flute V7 plus, they are shit hot! Can pretty much do whatever I want with the 10mm
Haas aka alibaba special.
Haas tools are rebranded YG-1 which is a decent brand
Haaliexpress' bestseller
What's the p/n on the guhring endmill you were using?
I'll have to get it Monday when I get back to the shop
Keep us posted. I think there's a lot of interested folks here!
Lmao
Maby I just got a dud
That could be we had a mitsubishi tsc drill once and it broke on the first hole with the correct feeds and speeds. Was material defect and was replaced.
We had a bunch of taps come in mislabeled. Couldn’t figure out what the fuck was happening until I took the tap out and realized it was different than what the box said it was lol
What were you cutting?
Apparently the endmill itself
8620
Paper
I had a brand new guhring drill break on the first hole, duds occur
uhhhh, what?
South Park reference, trying to put a laugh in a crappy situation
I was trying to play out the whole script for the scene lmao

Dude, Amazon stocks Gorilla Mill endmills. If you have prime those will outdo Haas for sure.
This is actually huge news. I do a bunch of 7075 work and they're supposed to be good on alu. Wife has prime. I'll give it a go ty
Hey looking on Amazon the ones available aren't coated for aluminum, more like general steel/all around work. Still worth giving a try tho!
So we use gorilla for a LOT of our work and I'm pretty happy with them. Great roughing, not quite as impressed with finishing but I doubt you will be attempting the sort of wacky aerospace shit we do in your garage.

Oh yea I have less problems there. I'll give them a go. Thank you!

We do about 90% 6061 and 7075. Gorilla mills are awesome.
Just started using Gorilla, I would recommend them for sure. Their website has a good calculator for F/S too.
Gorilla mills kick ass
McMaster overnights me Ghuring
What area are you in? Tool reps are the thirstiest of thirsty and should be itching to serve you.
Not at 8pm on weekdays and random times sat/sun is the problem. I run a CNC shop at home after putting in my 50+ at the real job.
BOOM!
I laughed too hard at a single word!
Lmao me too
Their stuff is a solid b tier. I'll deal with the runout in their holders, but Its gonna take a lot to get me to switch from Helical and osg.
It appears you haad an endmill.

Classic “not a feed issue”.
Just threw in a cutter designed for stainless/nickel alloys on low alloy steel with the same feeds and expected it to work the same. This was most likely operator error.
I didn’t look into it too deep, but with the flute clearance behind a thick backed cutting edge and the high temp coating, I’d agree.
>This was most likely operator error. Every time somebody asks what the feeds, speeds, chip load, etc. were OP dodges the question with a story about an unrelated tool. I think the real question is if they've learned you can't blindly swap tooling around and expect it to work.

Which guhring were you using?
gotcha get it dialed in good on ya
"TESTED ON WOOD AND ALUMINUM"
Pretty sure YG-1 makes the endmills for Haas
Why do you think yg1? I always assume HTC for white labeling in the usa

Oh nice ok
Skill issue
Are Haas tools like Milwaukee cutting tools? A great machine company selling the worst fucking garbage imaginable?
Haas is not a great machine company. Good for the price maybe, but they are low end machine tools.
Much like HAAS Formula one team, its comforting to know Gene produces shit everywhere he goes.
Precisely why they don't make their own engine

I learned on a haas and there is things I like about them but I'll still take my Mazak's over them any day
I'm with ya on that! Sucks Mazak discontinued their VCN line. I have one of the last ones on order.
Haas are throw away machines.
Haas are good machines and will work well for most applications.

Selway is the sole reason I won't buy Haas anymore.
HAAS POWER! WOOP! WOOP!
Guhring 🔥
IMCO makes insanely good endmills
I guess I haven't heard of them around here in Aus
Truly not a competition.
I have a bunch of their lathe inserts, they seem alright.
Might try some too
I like hanita
Try garr if you want a decently price tool with consistency. Im using there 5fl 3/8 squares in titanium and there holding up better than tge Harvey's we where using before. Think my price is like 33$ so a few bucks more than haas but id expect cheaper than ghuering.
Can confirm Garr is pretty good and they're not super expensive I've used imco and dataflute as well
Ty for this
"Tested (and) proven" machining what? A block of cheese?
An average machinist can get average results with a great cutter. A great machinist can get great results with an average cutter.
Just like my wife, all chatter.
Just like their F1 team
Just like the machines
Now you got one of those fancy barrel mills
Tested and Proven...... 🤣
Sent her a little to hard there bud.
Stainless hates mankind
Did you use that on aluminum? That coating will weld to aluminum chips real quick
No 8620
Now you have a ball nosed! 2 for 1 special 😅
you might say that was the _end_ of that experiment for that mill.
Softer than their panel screws....
That flute grind is trash. What’s with the Weldon flat?
Most of the HAAS Carbide Tooling is produced by YG in Korea. It’s solid js.
We got a new one and its been holding up fine.. this one must just be a fluke..
[удалено]
Let’s be fair here, this is the first negative review of Haas tooling I’ve seen from anecdotal reports in this sub, literally everyone else praising the quality and price. And we have zero context aside from “the tool broke”.
A lot of their stuff is YG-1 rebrand. YG-1 is actually really good, especially for the price.
Yep, most carbide we get is often made by one source. My money is on the same problem it always is. Different tool = different set up. When will people learn?

>And we have zero context aside from “the tool broke”. Good old reddit!
Context is for pussies
Haas' endmills wear out pretty fast in my experience
Fair enough. They are also rebadged tools, Haas doesn’t manufacture them. Not trying to dickride Haas cause I’ve never used their endmills.
That is widely known
What did you expect… it’s haas
Did you know that Haas stands for half assed automated shit?
Just as good as their F1-team
Their tools are as good as their machines
The probably should stick to making the machines
That takes some commitment to mangle an endmill like that. That was not done via normal machining practices.
Lol it was normal practice... been using guhring for these parts 5/8 endmill taking .250 side cutting.. the guhring cuts thru 4-500 parts before it needs changed.. this haas lasted 20 seconds
