Eltool right angle tooling

[Rotary Ninja]

Has anyone ever used these... www.eltool.com ? We are getting the 1D head for drilling. I modeled it up and it will fit nicely in a 1.300" bore with a tool sticking out .300" or so.

We have a few. They have very little power. We decided to make drill jigs and drill by hand. We used them on a Haas machine and the spindle orientation was pretty crappy. Holes were out of round because spindle kept rotating slightly. On a better machine with good TSC you might have better results than we did.

We are going to use it on a Mazak Nexus 510C-II. It only holds 1/8" tooling. But we have to drill 1/4" holes through 7075. So we are going to grind down a 1/4" endmill to fit in the 1/8" Weldon collet.

Jrygus,

 

What size holes were you drilling. We are thinking about buying the Titespot with the 1D head to drill a .218 diameter hole in aluminum.

We were drilling up to .221 holes in 7050 Aluminum. I believe we had to slow it down to 1 IPM. It can go faster, but if you do stall it, you will have to then repair it.

Just recently we ordered another one for one project (we have used them in the past as well). Ran it a couple of weeks ago on the integrex with hi-pressure coolant drilling Ø.100 holes in aluminum. It works fine. Never did any milling with them. Pretty flexible tool when used on a machine like integrex.

wish they had an air powered model for poor boys...

I think the boss bought the 1D. We are grinding down a 1/4" endmill to fit in the 1/8" weldon fitting. I am just going to use a point-point toolpath to plunge cut through about a .200" thick wall in a few places. Our Mazak only has 200psi of thru-spindle coolant pressure. Do you think this will be good enough?

 

Onr thing I did notice is the spindle orientation on the Mazak is a lot more rigid than the Haas.

Use the calculator @ the bottom of the page to get your power requirements.

You could control your RPM by changing the size of the hole in the retention knob.

They are very helpful and there is a 10 day trial policy as well.

We use them quite a bit. One thing we found out was that you should follow the cleaning instructions if they are going to spend much time not in use. We have been drilling Ø.221 holes for 4 or 5 years, but when we went to doing smaller holes with tighter location tolerance our spindle orientation (beacuse of the difference in lock up at tool change) was problematic.

 

I will be implementing our first run using an endmill pretty soon. We use the 1M heads for drilling anyway.

They make'em, not much torque, good for highspeed >20k.
