It will be on a Horz machine

Does anyone have any machine time with Koolcarb Straight Flute Coolant fed drills? I am starting a new job that has (3) .625 dia holes 4.25 deep and I have been using the straight flute Koolcarb...

What I am talking about is when you are engaged in a full cut at the width of the tool....the tool is actually climb milling on one side and con on the other. And by the way the spindle was on.

Well guys Im back again with yet another question. Ok...this is what we got...I have .950" thk AL 6" x 6"....Right now I am laying these parts flat and using a 9/32 ball nose endmill to cut a slot...

Thanks guys!! I ended up going with the Iscar TangMill with the I4050 grade insert. And they where having a special deal where I buy 30inserts and give them my old cutter and I get the new cutter...

It is a SPKN 42 Iscar insert. The cutter is a no name. We have tried numerous feeds, speeds, DOC. And I messed up on the material, it is Cast Iron. Should I use a neg rake tool machinig Cast Iron...

I am face milling 1020 steel with an inserted cutter with a positive rake. Its all I got right now. I am having problems with finish and inserts chipping. I am looking to get a new cutter with a...

Nevermind I found it. Thanks

I was using a Cobalt to start out with. I think that I am going to try to run a spot drill instead of a center drill.

It is 304SS...I tried these numbers and after the 3rd hole the drill burnt up. They are center drilling the hole and the tip is breaking thru 3 of the plates. Then we are coming back in with the...

its 304 SS

Where did you get the CNCSpeed software? Did you download it off of the net

Im using a split point 135 degree Cobalt Drill. I just didn't think that .003 chip load per tooth was that much.

Before I changed the feed and speed to what it is now...it would make it to the about the 7th hole and it would start squealing. Now since I changed the feed and speed it makes it thru about 50...

Just another headache. I am running into problems with my .128 drill that I am using to drill thru 4 .09thk stacked Stainless Steel plates. It is drilling 56 holes and before it gets to the end the...

Im machining 6061-T6 cast aluminum and I have to use a 1.5 dia endmill hanging out 6" for clearance. The problem that I am having is I am taking a 3.5 DOC .075 off of the wall and the part is...

Yeah that is what I thought I have already changed to a drill and tap. Just not enough clearance.

Anyone used these before? I am having a problem with run a M4-0.7 thru 3/8thk Aluminum. They keep snapping off. Also running 1/4-20 DRAP. Any help would be much appreciated.

Thats awesome! :D

You must of had some incredibly high spindle speeds?

So what kind of C-SP should I start out with using the parabolic drill. I am using .1285 - .438. Any suggestions would help

Well I am looking at the parabolic with the stubby FL. Do you think that will make a difference? I sure hope so because I think that they already ordered them. Oh well....let me know.

Do you have any suggestions? I am drilling 3/8 thk 6061-t6 plate. Multiple holes and dia.

Are you able to get some high feed rates out of these drills when using them on aluminum?

Thank you!

Can anyone shed some light on this style of drill "parabolic". Is it a good drill to use in Aluminum? If can you recommend any that would be good It would be much appreciated.

If anyone can shed some light on this subject. What is the difference in inserts when it comes to machining Aluminum vs Cold roll steel. Why are there two different inserts for the different...

The advice worked great on this job and I know that I will be able to apply it to many more like it. I used the T shape insert and up'ed my RPM to 3000 on CSS and fed it at .007". Awesome results! ...
