Spotweld Drill 3/8" Pro is rated 3.7 out of 5 by 10.
Rated 3 out of 5 by from Pricey for level of quality The spot weld cutter works but does not come with a usage sheet to guide you for correct speed (it was on the Eastwood spot weld cutter page) the bit did slip in my chuck a bit and this is a 6 month old DeWalt 20 Volt cordless. The shank could use either a tri-flat or hex shank to avoid slippage, the tip is a little too short for repeated sharpening. I would change the shank and tip design and reduce the price by $8 to $10 dollars.

Rated 3 out of 5 by from Good This tool cuts the spot weld well. I found that the tool walked when trying to start the cut. I overcame this by first making a small start hole with a #3 center drill. I found that some recessed places could not be reached and a longer shank would have helped. The steel and heat treating quality seems very good. I have only made about 25 cuts and the toll seems to be staying sharp.

Rated 4 out of 5 by from Good tool The drill does an excellent job cutting away the upper spot of the weld. The weld separates easily once the upper panel is drilled. The only downfall I experienced was the short length of about 1-3/4" inches. Once in the chuck it was difficult to have 1" of bit extending from the drill. Several times in close areas the drill chuck was too close to get the weld cutter onto the spot. The drill needs to be perfectly straight to drill. A length of 2-1/2" or longer would be nice.

Rated 3 out of 5 by from The double ended style works better for me. I am rebuilding the rockers on my '72 MGB-GT so have lots of spot welds to drill out. I tried both this bit and the double ended cutter and find that the latter works much better for me. This one moves around unless you use a punch or small drill bit to make a pilot mark first, it required a lot of pressure, and tended to slip in the chuck. It just didn't end up being worth the cost for me.

Rated 3 out of 5 by from Not what I was expecting The tool was nicely made, but requires too much force to use with a hand drill. I'm sure it would work fine with a magnetic base drill press or in a vertical mill. The other problem is that the centering point drills through the underlaying sheet that you are trying to save. I ended up drilling a 3/16 pilot and then using a step drill.

Rated 3 out of 5 by from Not Pleased, Won't Start Cutting Not sure if I'm doing something wrong (yes, it is spinning the correct direction), but the tool won't even start cutting. The point prevent walking, particularly after using a punch to mark the center, but the point won't cut anything to allow the outer teeth to cut the weld. I've gone back to the hole saw type.

Rated 5 out of 5 by from Great tool for the job!! I had one previously that seemed to be getting dull after maybe 25-30 cuts. Couldn't find it for this job (DOH!!), as it's been a few years, so I ordered another. Agree with others that it could be longer. BUT....nonetheless, it's the tool for the job!!

Rated 5 out of 5 by from Works well I've used this bit on over 300 spot welds, and has done a fine job. You can get a bit extension at some hardware store, to get into tight areas. I've just ordered my second bit. but I will try to get the original one sharpened.
