Rethink about Cutting tools

[ricky_fire]

Hi guys,

 

I have been using Sandvik indexable cutters & Fraisa solid carbides. But they are getting higher

priced yearly. Someone recommended to me Taegu Tec & Guhring respectively to bring down cost economics. Dear friends plz advise if it is worth making the change

Does anyone out here use Taegu Tec or Guhring ?

Do they perform and deliver results like we expect from Sandvik & Fraisa ?

Kindly advise

 

[Thad]

We recently switched to Taegu Tec and are very happy with them. We get very good insert life out of them cutting A2 and D2 tool steels. They last forever on machine steel. The inserts are lower priced also. They hold up fairly well cutting 58-60 Rc on the occasional repair job.

I tried Guhring and found i got same tool life out of there bull and ball cutters for hardened tool steel.But the endmills were no good compared to Sandvick or Titex?

WHERE DO YOU GET TAEGU TEC .

I WOULD LIKE TO FIND A VENDER HERE IN ALABAMA.

IF YOU CAN HELP PLEASE LET ME KNOW

[crazy^millman]

How about Fullerton I have had good luck with their endmills.

[Thad]

Rex, check with the local Ingersoll dealer. I believe Ingersoll bought them up.

I've never heard anybody refer to Guhring as cheap but I guess if you're using Sandvik's solid tools they probably are. We are almost exclusively Sandvik for our indexable tools but we use NONE of their solid tools. $$

 

I use Guhring drills in high-performance applications where I can't get anything else to work and they've never let me down. I'd use 'em for everything if they weren't so much $$.

 

For 'regular' carbide drills we use MA Ford & Metal Removal. For carbide E/M we use Fullerton, SGS, Niagara

 

These are probably all cheaper than Sandvik

We use Taegutec inserted mills, with the APKT inserts, with good results. The inserts are relatively inexpensive, and we like the larger inserts because they are more forgiving when they break down. We don't have to replace cutter bodies as often. We are currently looking at Mitsubishi inserted mills, because Mitsubishi has a policy of replacing their tool bodies if they do get trashed.

1 nice thing about taeg. is the 1 style insert can be used in more than 1 cutter.

[Jean-Simon]

Used Taegu Tec also with good results in A2 and D2 as Thad (Die making) but need to be careful with the speeds they give in the books are a bit high. Guhring haven't used them but have seen a demo, they seem to be really good tools but pricy.

Due to the high public profile of my employer, I get a lot of tool reps trying to get our business. Nobody makes a tool that can match Hanita's Varimill in steels. Period. I have a program that runs production in which the Hanita has a 10-11 hour tool life. This is my testing program for new tooling. I have tried several top name endmills in this program, with amazing results. SGS TiAln lasted about 8 seconds, then exploded. Similar results with Niagara, Fullerton, and Robb-Jack. Hanita's design eliminates the need for a roughing tool, it can handle full slot roughing at full diameter depth. At carbide speeds.

 

Not a commercial. Really. Just my first hand experience. Now when I talk with tool reps, I tell them what I use, and how I use it. They just shake their heads and tell me that they can't provide a tool that can match what I already use.

I prefer Guhring for high L/D ratio drilling apps. But Titex works very well as well. Guhring makes killer Ceramic Drills for the REALLY hard stuff.

When's Jesse gonna wear a Hanita shirt on Monster Garage?

 

All kidding aside, is the tool you're talking about the one where the pitch between flutes is uneven to break up the harmonics of the cutter? The guy was just in yesterday talking about that one.

 

The SGS Z-Carb is pretty cool; is that the one that blew up in 8 seconds? Bummer

Yes. And no, don't expect to see Jesse with a Hanita shirt on... They don't cut us much slack in pricing. The tools are not cheap, but they make up for the cost in performance.

[chris m]

We've never really used them [Hanita]. Most of our stock removal is in turning but when we do milling is is usually in sh!tty materials like PH stainless and 4340 where we're milling gummy stuff that's 34-38 Rc so maybe I'll test a couple out instead of using the Z carb

That was great

 

Thanks Thad,DavidB,Chris M,Smit,DaveC,Jean-Simon & James Meyette

Thanks to all u guys for your advice and info and especially quick response.

Some of u guys mentioned about Guhring drills being great. What about their Taps. Are they hot too ?

Have any of u guyz used them

I have heard about their 'Fire' coating too

1/2 Varimill, full cut, .500 DOC, 2140 RPM, 17 IPM.

 

Try that with your endmills.

[Hacsta]

sounds like those varimill's are the deal. we cut alot of stainless, gonna have to give them a try

[ricky_fire]

Hey guyz !

 

Give me some parameters for Titanium & HRSA work materials

Aerospace buddies are u around?

I think that the half of the endmill that's in the collet would be OK

 

I think I'll cal that guy back...

Hey Chris

 

Tell me some more about SGS Z carb

Is it that gr8 !

Taegu Tec endmills/facemill are a POS. I think the material they're made from is too soft, thats why they don't last. I managed to crash one of them, and damaged all the insert sits areas, what a waste of money.

 

I've crashed other tools before, but atleast i was still able to use them later.

I thought toolholders were made of >43HRC material

CORRECT ME if I am wrong guyz!

[EX-wccprogrammer]

No, holders normally are not too hard... Sometimes case hard is all.

[Mackius]

to ricky_fire, well i've used sandvik and ingersol insertable endmills and managed to thoroughly abuse them and still the areas where the inserts sit, stay intact. Sure there is some deformity on the insert sit areas, but you can still continue using them.

 

Taegu Tec on the other hand, if you crash them , kiss that insertable facemill/endmill goodbye.
