How to remove a broken tap / drill bit the easy way

I recently broke a tap in a newly made aluminum power steering bracket for my 1929 Ford Hot Rod. Several methods of removing the tap failed. Upon a bit of research I discovered that the tap, drill bit, or even a steel screw/bolt can be removed effortlessly by boiling the aluminum part in a water and alum solution without destroying the aluminum part. This was so simple and worked very well.

Great video. Even as an engineer, I find myself learning new 'old' tricks daily. Great video, very helpful.

Dissolving alum in water creates a low saturation sulfuric acid. Boiling the water creates a stronger acid, but not to the point that it effects the aluminum. Aluminum has a slow reaction to saturated sulfuric acid, whereas steel has a rapid reaction. Making an unsaturated batch and then boiling it provides enough reaction to dissolve steel, but not aluminum. On a side note, the bubbles that are produced by the reaction (not the boiling water) are hydrogen.

Wow!! Just did this on an aluminum engine mount for a RC engine. The tap broke in the aluminum mount. Had to boil about 2 hours and the hole is empty!!! Amazing!!!!

Saturated solutions react the fastest but the actual alum consumed per unit of iron is more important to completing the reaction and will be something less than 8:1.

It does work, but I used it for 12 hours straight just to see that a small fraction of it was dissolved, then let it cool over night and had to repeat the same process twice more. It did remove that broken tap, but only after 36 hours(a lot of gas)!! so it was a nice experiment for me, but I don't think I will use that in the future.. By the way the aluminum was boiling too so I have no idea how that affect its mechanical performance only time will tell.. it did not dissolve but it did boiled nonstop for that time...

@1929fordhotrod 7 жыл бұрын

I suspect you did not have enough alum in the water. Add enough alum to saturate the solution so that no more will dissolve in the water. The temperature of boiling water/alum solution will not affect the aluminum

@nirophek1303 7 жыл бұрын

I think that the solution was saturated, since after adding couple of time alum to solution it started crystallizing at the bottom... about the temperature I don't know if it changes the chemical behavior of the alum with aluminum but it certainly increases the speed of reaction... in both cases cold or hot the aluminum did boiled meaning it reacts with solution for sure.. but it could be contamination in it...

@1929fordhotrod 7 жыл бұрын

The solution needs to be boiling and will not hurt the aluminum and will dissolve the broken drill or tap quickly. The aluminum will discolor but does clean up nicely afterwards with little effort. What exactly were you removing from the aluminum and how big was it?

@nejiniisan1265 7 жыл бұрын

Nir Ophek you changed the behavior. You need to saturate the solution at room temperature.

i had metalshop in highschool, when the libtards hadnt yet arrived . no one lost an eye or cut any fingers off. we had knowledgable, passionate teachers. what we find today in stores is only the second - step ''taper'' tap. the ''starting'' tap is used first. if its a blind hole and you need threads as close to the bottom as possible, use the ''bottoming tap''. use a sharp tap, dk.brown threading fluid is an all around lube for drilling/threadind. when you are ''in the hole, make SURE you clear the chips from the tool. on a critical part, i cant risk, i back the tap out a full turn or until i hear click of the chips ''unbinding'' . i havnt broken a tap that couldnt be removed w/ pliers or tap extractor in 20 years.

Wow, you have a difficult situation. Your method will not work. The part needs to be submerged in the boiling solution. Maybe a local machine shop can help using an EDM (electrical discharge machine).

@Slimandthegeeks 5 жыл бұрын

you can also punch the tap out or drill holes around it and work it out, , then have a welder fill in the hole, grind it smooth and re-tap, this may destroy any heat treatment of the piece but if you are in a hurry and have a welder available, the process can be done in about an hour.

Hi what if the part is to big to boil, i have a broken exhaust bolt (Hardened steel) in an aluminium head and dont want to remove the head, can i heat with a touch. I have managed to drill it out so can just see the thread but its fused in and cant be picked out.

@1929fordhotrod 7 жыл бұрын

Before drilling you could have carefully mig welded a nut to the broken bolt to remove the broken stud. Now the process is a bit more difficult. Lots of penetrating oil, and patience with a scribe. Maybe even a bit of heat from a propane torch and shock it with oil to loosen whats left in the hole then pick it out with the scribe. Once its removed you might need to re-tap the hole or even install a threaded insert. This is definitely a challenge. Good luck.

@1929fordhotrod 7 жыл бұрын

No, it is aluminum potassium sulfate and is used in pickling and tanning. Here is a link for it on Amazon www.amazon.com/Barry-Farm-Alum-1-lb/dp/B00016Q6BK/ref=sr_1_3_a_it?ie=UTF8&qid=1478581446&sr=8-3&keywords=alum

@nejiniisan1265 7 жыл бұрын

wayne drew try to see the fertilizer formula "potassium aluminum sulfate" or KAl(SO4)2. You can also find in drug stores as alum, those stones you use to close you pores after you shave. Also you can go to the art supply store and ask for alum based mordant.

Hi. Im hoping this works 4 me. We had a bolt break off in my timing cover we were able to get that out with the tap but then the tap broke off in it and I got 2 of the little things of the alum from the grocery store but apparently that wasn't enough cuz it didn't work is started bubbling out the hole some but that was it so now I just got three and a half pounds from Amazon and I put like a third of it in the water about how long do you think that should take?We just have the end of the cover where it's broke off in the water so there's not a whole lot of water but it's enough to that it's over the broken trap. So just wondering if you could give me any kind of a timeline on about how long that might take to dissolve it? And thank you this is been so helpful as opposed to having to go out and buy a whole new timing cover.

@1929fordhotrod 5 жыл бұрын

Dissolve enough alum so the water saturated with it. The part I did in the video took a couple of hours to do. I also did this outside on a hot plate in a glass dutch oven I quietly borrowed from the kitchen. My best advice is to pull the part every once in a while to see how its doing till the tap is dissolved. Good luck.

What is alum

@darkshadowsx5949 5 жыл бұрын

usually a hydrated double sulfate salt of aluminum. Potassium alum, KAl(SO4)2·12H2O, also called "potash alum" or simply "alum". Sodium alum, NaAl(SO4)2·12H2O, also called "soda alum" or "SAS". Ammonium alum, NH 4Al(SO4)2·12H2O.

Make sure you use a lubricant while cutting the threads. Also take your time and back the tap off every 1/4 turn. It happens to the best of use.
