I was able to drill it out with the Dewalt Carbide tipped bit. It was still tough and slow. Once I got a hole all the way through it, I needed to drill for tap size. I wasn't getting anywhere with the colbalt bits so I decided to try and use my bench-top drill press. The reason I didn't use the pres...

I'm using a hand drill (a Dewalt 18V). It runs at 450 rpm or 1500 rpm - I using the high speed setting. I got the Dewalt "cobalt" drill bit set mentioned above - but they wont dill through this Allen head set screw either. I am making some progress (I'm about 70% through it) but it is taki...

I see the carbide tipped bit listed under "masonry bits" on the Dewalt site. https://www.dewalt.com/products/accessories/concrete-and-masonry-accessories/multi-material-bits/multi-material-drill-bits I've tried masonry bits before but hey didn't have the right cutting tip/angle for metal, ...

I've been researching this since my post and wanted to reply back on what I learned in case someone else can benefit. This was a nice "professional" overview of drill bits so anyone interested https://www.youtube.com/watch?v=sykjB7fS1Po Basically, 1) Carbon bits are the hardest. But not re...

I'm posting this question on this welding forum because I think most of you do machine-shop work and probably deal with broken bolts a lot. I'm trying to drill out a seized "Allen head setscrew" in an aluminum housing. The setscrew diameter is around 1/4". I have tried a number of bit...

After reading through some of the product reviews here (and watching some YouTube videos) the PrimeWeld 225 looks to be in my price range and has some really good reviews. It looks like it will weld about anything I have. I would just be welding everything with TIG (no MIG or stick). I have no exper...

I see the Eastwood welder only does "DC" TIG and DC Arc (the welding videos say one needs "AC" TIG for aluminum) - and with your comments about not being able to weld thin or thick aluminum, I guess I should look elsewhere. Do you have a recommendation? I would like to buy one we...

I looked at the (1) Eastwood Elite MP200i (dual voltage, MIG, TIG, Stick) with a spool gun for aluminum it runs about $1,060. Has a three year warranty. The other choices are the (2) Lincoln 210MP (dual voltage, MIG, TIG, Stick) 5/3/1 warranty. Runs around $1,600 with the spool gun. And the (3) Hoba...

I'm looking for a medium-duty welder for home/farm use. I had a Hobart Handler 140 but it was too light duty. Sold that now looking for something a little bigger. I see Eastwood has a Mulit-purpose (MIG, TIG. Arc) welder for around $800. It is dual voltage 120/220V, 200A welder. Does anyone have han...

I'm planing to do some custom exhaust work. I have the Hobart Handler 140 (Mig). I'm a beginner welder with Mig. I want to weld a stainless steel "Catalytic Converter" to 3" steel (aluminized) exhaust pipe. The exhaust pipe is 14 GA. Should I get Stainless Steel .023 wire (if so, do I...

That's a good idea.
After the fitting is welded to the tank, I will put in some Eastwood gas tank sealer, let it cover the inside around the fitting/weld real good. That should take care of any possible pin holes.

From what I've been able to find on the internet, I should select the voltage and wire speed for the heaviest metal and then direct all the heat to the heavier metal. Some of the puddle will flow onto the lighter gauge. I'm trying to weld a fitting (AN -8) to the bottom of a sheet metal fuel tank. T...

I have 120V Mig welder. I've done enough welding of heavy steel (like 1/8" and 3/16") to be pretty good - when the pieces are the same thickness. But now I have need to weld a heavy gauge "AN Bung fitting" to a light gauge fuel tank (in case your wondering - the tank is new so no...
