Spot Weld Cutters

finefettle · Posted: Sat Dec 06, 2008 2:54 pm Post subject: Eastwood spot cutter

My Eastwood spot cutter lasted about 10 welds them gave up. I switched to Dewalt Pilot point drill bit (5/16 I believe) and it worked great.

I am currently removing my rear package tray as it is rotten and i tried a 3/8 bit but it is hard to tell when to stop and i either go all the way thru or I make a dent but then have to try to pry it up and it never just pops loose..
TIPS?
How do I get it off without punching thru and not prying the crap out of around each weld. It leaves bits of metal behind that I have to grind down.

This is what worked for me.

What I did was scuffed up the spot-welds with sandpaper to make then stand out, then make sure your centered on the weld. If the bit walks on you, you may have to use a center punch. The key is to drill SLOW. Not like stupid slow but with the thin metal you don’t want to go at it high speed. With a good sharp bit, steady speed and pressure, you should be able to cut the first layer of metal with one or two full turns of the bit.

The ones I used that looked like that often had the teeth break off.

I ended up using the same one as you did there from harbor freight. Only thing is that yes the cut is pretty big. Anyone know where I could get one smaller in diameter?
I tried a drill bit also but it would barely do the job. Is there a specific bit that any of you used out there that made easy cuts?

The Harbor Freight one worked great for me. Can't beat the price, even if a tooth or two breaks off after 50 spot welds. Just grab another!

I'm having success with Irwins turbomax bits. Better than pilot points. Just take your time.

Where did you get them at?

I found a set at Lowes for around 15 bucks or so. It even had a 1/2" bit with it. I use oil when I drill and I've been using the same bit for 40+ spots so far. Still sharp Smile

I have one similar to this but it is made by blair. I was breaking teeth like crazy until I decided to drill a small dimmple in the middle of the weld first. The bit stopped wandering and I now get a lot of cuts out of one bit.

Well, I bought one of these a few months back, but not from Eastwood. It was from a local tool store for the price of $17.70 for a 3/8" cutter.

I works great by cutting the metal on the top layer rather than requiring both panels be cut. I recommend it over those crappy cutters with the drill bit that has the circle with teeth on it. I tried one once and it couldn't even cut butter.

I drill more spot welds than I care to remember, every day practically. This is the back , elbow and wrist saving"est" tool I've ever purchased:
http://www.dentfix.com/viewItem.asp?idProduct=17&a...SS_Capable
Nearly effortless.

Hard to swallow the price at first, but WELL worth it in the long run. A hobbyist would never wear it out if it wasnt abused. Comes with an inline oiler attached.

And if you cant get to the backside, you can remove the clamp and it still works better than any spotcutter bit out there, and I've tried every single new thing that came along on the tool trucks until I bought the spitznagel.

Second best is the style of bits posted by finefettle, a very distant second.

I'm rebuilding a 71 standard bug and I need to take the whole front end off (not worth fixing), what's the best way to get a good clean disassemble?

I just bought this one.

I'll never use anything else.
