Twisted cutting edge increasing the corner stability, enabling soft cutting action even at highest ramping angles.
A precision faceted eccentric relief reducing vibrations and reducing friction. For excellent cutting conditions in multiple materials.
Innovative chip gashes within the flutes reducing cutting forces and supporting efficient chip evacuation.
HARVI I TE - Maximum metal removal. Maximum productivity. Maximum benefit.

It's insane how quickly cutters are developing even from when I started only 16 years ago
I suppose that's what happens when you give smart, motivated people unlimited R&D budget 🤣
The present: How to NOT break the TOOL. /// The future: How to NOT break the SPINDLE...
While Titans of CNC may be over-hyping these tools they are definitely considerably better than "standard" endmills.
That said, I'm impressed at how it can mill 1018 steel without leaving a torn-up fiinish, something that is quite often a challenge with the material.
very impressive, 45 deg ramp is nice. a demo on creating a hole with that tool would be cool
Great video! The Harvi 1 TE can slot to a depth up to 2 times its diameter.
that tool is a beast.
Plunging at 920mm/min... Holy cow
If I only had a machine that could run this.
@ 2:51 it ramps with 1798 m/min. That's impressive.
Amazing..
1:13 why would you keep a mic In your back pocket
BRUHHH indeed
Belongs in a case when not in use for sure
It’s not harming the mic at all? What’s it mAtter? As long as the mic is not dropped or knocked it will measure fine
@@mitchelldafoe8445 it's more likely to get damaged, but more to due with body heat causing the mix to measure wrong when working to tight limits
rockaboy2 yes that is true it is more likely too get damaged, and yes if u we’re working microns body heat could affect things, if working in tenths tho body heat won’t affect much
Is that machine a DMU monoblock? That (DMU monoblock) family is one of the most stable construction :) Anyway this end mill is nice :)
It is a DMG Mori DMC 65 monoBLOCK!
Pretty amazing!
That is SICK!!!! And no lube or coolant to boot IN 4140!!
Air blast for chip evacuation is all that is needed in a lot of materials when using carbide tooling. In fact, using coolant can sometimes reduce tool life due to thermal shock causing micro fractures in the cutting edges.
At 2:20, you can actually see the end mill deflecting, and staying that way all along the cut. Very interesting.
Don't think so. Optical illusion.
The regular HPHV are amazing at slotting too.
Impressive
Able to cut at any deph, is amazing.
Can I use this for roughing and finishing? We use a "corncob" type cobalt rougher for steels and finish with carbide.

Greetings from Canada. Very impressive. Just wondering how you sharpen a cutter like that or is it just ground with regular angles and relief and then used for other less demanding operations? Work safe.
You don't sharpen it. You buy a new one when it gets dull.
Did you ever tried to cut Trip Steel? I think the tool will break.
I can just imagine the screams that would come from my Haas if i did any of this!
LOL the HAAS would be doing the cha-cha slide across the machine shop.
when you test endmills, do you step up the feed and sfm until it breaks?
What was the spindle load at 2xD slot milling ?
Impressive but what kind of tool life can be expected?
And did the same tool make all those cuts?
@@jbmaleprostitute6630
i doubt it was the same tool. notice when cutting the slots the film would blink forward, and not show it rapiding to the next slot. i figured either they changed tools, or stopped to let it cool for a while.
What kind of horsepower and torque do you need to actually be able to achieve this. I feel like the machines I am using lately (Kitamura Hx300G) would have to have the spindle replaced after doing this for a week. Maybe the Matsuura H300 could do it but I don't know.
I won't be able to select between machines and manufacturers, but those values for example for the 1/2" cutter at 60% engagement, .750" axial loc, 590 sfm and .0028 IPT.. the Power at tool (Pcut) is 7 HP and torque at tool (Tcut) is 8.15 ft-lbs
What type of steel are you working with?
On acrylic block test?
thats impressive at 3:27!
What machine are you using for this demo please. HP and spindle taper size and type? What kind of tool holder are you using? If my machine is not up to the same specs then the tool is no good to me no mater how good it is if I can not duplicate these results in the workshop.
We used a DMG Mori DMC 65 monoBLOCK, 47hp, the spindle is a KM4X63™ and a HydroForce™ tool holder!
Would you use some form of coolant in real life situations ?
Is this dry operation just for demonstration and filming purposes?
yes...
not usually in steel. thermal shock will fracture the carbide and cause early tool failure. Aluminum almost always requires coolant to prevent the material from galling and clogging the cutting flutes
If you get your SFM right in the sweet spot it's actually beneficial to run without coolant in certain types of material, like what they're filming with.
@@blob_87 It's the coating that gets fractured by the thermal shock. Then once the coating is gone the Endmill will be gone also.
What kind of steel material was it for the test?
This was 42CrMo4, which is a Steel between 35 - 43 HRC.
I'd like to see an M.A. FORD endmill do that!! *cries in broken endmill*
🤣🤣🤣
valider par la street
And here I am on my CMX 70 U having to use regular HPC-Endmills... At least I've got enough time for coffee
Hope you enjoyed your coffee... In the meantime, anything we can help you with?
Booom lets make it happen ;-p
okay tidan
FZ meaning
我想了解这样加工刀具能用多久!
I would honestly say that it would take the same of time if it was a standard carbide end-mill ....the " mixture " of carbide and the special clearance angles make the cutter do what was shown .I am just a retired machinist since 1973 .
Go on Kennametal.com they may answer you with little more explanation.
What Material is it 42CrMo4 ?
42CrMo4 is a material designation for a type of Steel. If you are familiar with ISO material groupings, this material would be part of the P4 group, which has a hardness between 35 - 43 HRC. I hope that helps!
👏👏👏👏👏
What holder is that
We used a HydroForce™ tool holder with a KM4X63™ connection!
WOW my 3 HP Proto trak would yell for mercy , " what did I do wrong " if I did that .
Hi, I'm china, don't mind me, just stealing your tech
Ha Ha... Good One...
"Introducing new Super Carbide Cutter #1 Good Time End Mill!"
Che materiale sta lavorando?
Hi Stefa, for this demonstration we used a block of 4140 Steel!
Heloo new friend here hope I can get in return stay safe and bless
Poor guy who squared all that steel up for that..
Which is the workpiece material ?
Thanks
Hi Giacomo, for this demonstration we used a block of 4140 Steel!

$200 end mill
What a creep.
Pls stay away from titan, he is
a joke
That dude is the Vince McMahon of machining
Why? Im new in the trade and yet not really able to seperate the good from the Bad
Nothing wrong with Titan. He just focuses too much on tooling. Not sure if he's much of an actual machinist though.
