What are the best drill bits for hardened steel? I am really a "use heat" kind of guy. This started when I worked in a gas station back when gas stations did mechanical work.

When removing or replacing exhaust systems from the cast iron manifold, my boss always had me simply heat the nuts on the manifold studs red hot and then remove them. His feeling was that the extra few minutes it took to heat the nuts was a drop in the bucket when compared to replacing broken off studs.

He was right and it always worked. I'd bet that the bolts that broke are around the exhaust. They're seized in there, that's why they broke off to begin with. You can forget an easy out.

Heat above degrees will break down the rust, probably ruin the block also. Grind a small punch at a 45 degree angle and use it to peel the rest of the bolt out. If this doesn't work ou can grind the rest of the bolt out and use a tap to start getting the threads out, this will require turning back and forth, cleaning often and blow out with air. If you don't clean the tap and the hole often enough, you may get the tap stuck in the hole.

Once I twist the head off a stuck bolt, I then like to build up the flush bolt top with drops of weld to grab with a vice grips. I do this with a tig torch, and as slowly as possible. This puts me in the minority of people, as most people don't have a tig torch in their shop, and if they do, cannot get it to reach the broken bolt.

An arc welder would be the next best choice. This method almost always works I think, because when heating the bolt while applying the weld, the bolt tries to expand, but it can't expand very far, so, since the metal has to go someplace, the bolt becomes longer. Then when it cools, it becomes thinner, contracting away from the threads a little, and is consequently easier to remove. I don't know if jumping to "heat" right away if a bolt is stuck is a good idea.

I like the expansion and contraction aspect of heat, but removing the heat treating from the stuck bolt is now a question I do not have an answer for. I used to simply try to eyeball my center punch mark, but it never worked out that well. One problem is that you see the major diameter of the threads on one side of the hole and the minor diameter of the threads on the other side. Even so, getting down close to the hole with a magnifier and using a 64ths ruler has helped me a lot.

I find center as best I can and scribe a light line. Then I rotate 90 degrees and scribe the other direction. Then look to see how well it looks. I measure again and correct where I can. Then I lightly center punch, and check again with the magnifier to make certain that I really punched in the right place. Then, as mentioned in other articles, start the hole slowly with a center drill. Just recently, wheile discussing the problem with some antique tractor guys, a fellow told me the following: I use a dial caliper to help me find center.

I always know what the thread is, so I can find the minor diameter of the bolt from tables. Once I have that number, let's say. Then, I locate side of the hole where it is obvious that I am seeing the minor diameter of the broken bolt and measure in and scribe from there. Then to get a line at 90 degrees to that one, I can estimate how far I am from the minor diameter and make a second mark.

Another way to get the old bolt stub drilled in the center is to use the head or other part bolted up with the other bolts. Now, you have good guide for a transfer punch. I suppose if you were really a type A person, you could make a bushing for the bolt hole in the head or other part to drill the stub square to the head or other part.

These drill bits have a unique point on them that allows them to start on contact for clean accurate holes and reduced lock-up on breakthrough. So it acts like a tiny center drill. I have used them many times in the past and they work well. The only downside is that you can't sharpen them when they go dull because of the complex geometry. But that's a small price to pay for the time they can save. One last comment about getting the drill started exactly where you center punch: Whenever you center punch a piece of metal, you do make a dent in it, but you also RAISE a tiny "valcano" around the dent.

A flute of your drill bit might catch on this raised portion around the dent and cause the bit to wander a little. The avoid this, I file off the "valcano" before drilling. You can freeze the bolt and nut or other fastener using a small can of Freon. Use a refilling kit and valve to direct the flow of liquid to the fastener. Sometimes freezing alone will loosen it. Other times alternate between heating and freezing as this widens the temperature gap and increases the expansion and contraction of the material.

It's also of use for jobs where safety dictates that you can't use an open flame. This is not to say it is for every job but another option to use in conjunction with your other techniques. Bruce added these comments a couple of hours later: Hey Pete. The best deals are usually sales at Walmart and the Dollar Stores. You just have to watch for it to go 'on sale'. I seem to always need the stuff so when I find a good deal I buy a couple of cans.

All of my cars that used R I've converted to R a and it works great. About 20 years ago I sold a whole case of R that I bought for 99 cents a can back in the day. In retrospect I didn't get near enough for it! I rarely ever see it for sale anymore. A seized screw normally leads to a stripped screw that then leads into having to drill it out.

Next World class alternative tools to Snap on and US truck brands. Insert your screwdriver firmly into the hole. Rotate the screwdriver slowly and try to remove the screw. Apply a lubricant. Spray the screw head with a rust penetrant. Allow the rust penetrant to sit for 15 minutes. Reapply the rust penetrant. Tap the stripped head 5 to 6 times with a hammer.

Retrieve your screwdriver and attempt to remove the screw. This product contains grit that will allow your screwdriver to grip the head. Insert your screwdriver into the head and try removing the screw.

Method 4. Gather the supplies. Even if you are not a skilled welder, it is possible to adhere a nut to the stripped screw head. Purchase a super strong welding adhesive. Find a nut that is the same diameter as the screw head. Adhere the nut to the head. Place the nut on the screw head, making sure it is centered. Carefully fill the nut with the super strong welding adhesive. Allow the product to dry the recommended amount of time.

Remove the screw. Make sure the nut has completely adhered to the screw. Grab a socket wrench and place it on the nut. Rotate the socket wrench and remove the stripped screw from the surface.
