A spot weld drill bit is a very handy thing to have around the house. They are typically used for drilling holes in metal, but they can also be used for other purposes like cutting through concrete or stone.
The best part about them? They’re inexpensive and easy to make! This guide will show you how to make your own spot weld drill bit, all with items that are probably already sitting in your garage.
There are many reasons why someone would want to know how to make a spot weld drill bit. One of the most common reasons is that they need one for their car or another piece of machinery. This can be especially useful if your power tools have broken and there’s no way around it you’re going to have to manually drill each hole out.
How to Make a Spot Weld Drill Bit
1) Materials needed
When you are ready to start, you will need the following:
- A bench grinder or an angle hand drill
- Spot weld drill bits. You can buy them online or use other metal cutting tools such as dremel cut off wheels and grinders. There are many different sizes needed, so stock up! If your DIY project allows it, grab some extra pieces of spot welds just in case you break any while drilling.
- Optional but highly recommended is safety equipment, including gloves and goggles.
- A vice or something sturdy enough to hold the spot weld drill bit still as you work with it (and another safety measure). If your bench grinder has a place for accessories such as sanding disks then that will work just fine. You can also use pliers, clamps, etc. Just make sure whatever surface you choose won’t damage the metal of the drill bits when they rub against them during grinding and drilling operations.
2) Prepare the spot weld drill bit
Next, you need to prepare the spot weld drill bit. You will want to find a sturdy surface and start with the bench grinder if you have one available. If not, grab your angle hand drill or another tool of choice for drilling metal.
Make sure your tools are very sharp before starting any DIY project because dull bits lead to broken pieces, resulting in wasted time and money! Vice may be helpful here but is certainly not necessary (you can use pliers instead).
3) Start the drilling process
You should start with a straight piece of steel and begin to drill. The goal is to penetrate through one side entirely but not go all the way through, so it acts as an anchor or guide for future spot weld drills. This first cut will be left in the scrap pile because you won’t need this any longer once your DIY project gets underway!
If you are using other cutting tools, remember that they can leave rough edges that may damage other components or materials (it’s best to sand them down before use).
You should continue grinding and then drilling until you have two holes at each end of where you want your hole pattern to appear on whatever you’re working with. The distance between holes should be about the same as you want your finished product to end up.
Remember, if at any time during these steps you feel unsafe or uncomfortable with how things are going, then stop what you’re doing and take a break. You can always come back to it later when you have more experience!
4) Place the spot weld drill bit
Once you have two holes on both ends of your metal, it is time to place the spot weld drill bits. Make sure they are facing inwards! If needed, use pliers or whatever other tools you may have available to hold them steady for this step.
Then attach them with a small dab of super glue (or another strong adhesive). Be careful not to get any excess glue on the top surfaces that will touch your work material because then it can cause damage while drilling and grinding later stages which leads back to safety issues again so do be cautious when gluing these down especially since many adhesives take some time before drying completely depending on how much was used.
5) Drill the center holes
Once your spot weld drill bits are secure (and dry if needed), you can start drilling out the middle of your metalwork material. This will be where most of the “meat” is in placing screws, bolts, nails, or whatever else you need for later use.
Make sure not to over-tighten anything that requires these materials because it could lead to cracking, leading to more safety issues and wasted time!
You should continue until all areas have been drilled through completely so they appear similar in appearance to a small chain link fence when looking down at them from above. It’s OK if there are differences but just make sure any pattern follows this general idea when viewed from overhead!
6) Grind the raised surfaces
Now it is time to give your spot weld drill bits a nice smooth surface so they will be safe and easy to use. Grab your bench grinder again (or other tools) for this step. Make sure you hold them securely because these can become quite hot during grinding sessions!
Start with the most abrasive wheel first, then work up through each level until you have reached an acceptable state of perfection or near enough anyway which leads back into safety issues yet again since there’s no way around that unfortunately but at least we all know how important it is now, right?
You should continue going over these spots until they appear as desired from every angle possible too. If needed, go over them once more after using finer grits of sandpaper to smooth them out.
7) Install the spot weld drill bit
Install your spot weld drill bits by sliding them through from one side to another. Once they are completely slid through, tighten any hardware such as screws or bolts until you have a nice and snug fit, depending on what worked best for your needs!
You should always check these periodically (every couple of uses especially) because if they come loose, then it can cause other parts to loosen up, which leads back into safety issues yet again but we’ve already gone over that right? Remember how important all those basic power tool safety rules really were now too, even though this is only a small example compared to our regular everyday lives!
8) Final step!
Congratulations on completing your spot weld drill bits, and if you followed the instructions properly, they would hopefully work as expected for quite a long time to come.
You can now use them in any way that may benefit from their unique properties such as drilling holes sideways through surfaces which is much easier than doing it vertically or horizontally normally speaking but also makes it easy to see where exactly you’re going since there won’t be anything blocking your line of sight like usual.
When you are finished, make sure to clean everything off with water and soap (or another cleaning agent of your choice) so no oil or other residue gets left behind. This can cause damage later on if not taken care of properly!
