Introduction: How to Drill Straight Holes Without a Drill Press
Want to learn how to drill straight holes without a drill press?
Don't have a drill press, or can't take it with you to a place where a drill press can't be used
Don't want to invest in a $30 drill bit guide, aka a chunk of steel that has a few holes?
Want to tap a few holes for a small project, and don't want to buy a $100 hand tapping machine?
In this Instructable, I will show you how to make a simple drill bit guide, which can be used forbe used for anything fro, woodworking projects (my intended use), drilling into walls, tapping, like I mentioned above, or any other household repair.

Step 1: What You'll Need:
I made it for free since I already had everything that was needed on hand. By everything, well, I mean one thing :)
Hardware & Materials:
Steel square tubing (more on that in the next step)
Clamps or a homemade vise!
Drill & drill bits
Subjects: Woodworking, Metalworking, Making your own tools, & ᴸᶦᶠᵉ⁻ᴴᵃᶜᵏˢ
Approximate Time: 15 minutes
Difficulty: Super Simple!
ALWAYS USE PROPER PPE.
Step 2: Find Some Metal
After a quick look in my metal collection (all salvaged, of course!), I found some square steel tubing that was salvaged from a Stepping/steps machine, whatever those things are called. It had a factory edge, which is what I was looking for (the factory edge still has paint on it).
Unless the piece of metal had some obvious use, I don't think there should be a reason for the factory edge not to be 90 degrees, but I made sure that statement was true with a try-square.
Step 3: Cut!
I clamped it down, and then cut the square steel tubing to a length of almost 4cm (~1.5") with a hacksaw. You can debur the burrs with a file if needed.
I like using a ketchup bottle for dripping water in the cut which lubricates and cools down the blade. I've done this before , but when I tried it now, it made the chips clog/ get stuck between the teeth of the blade. Anyone know why, or have a better method for doing this?
Step 4: Drill! (& Some More Tips)
Some more thoughts and tips:
- PAINT SIDE DOWN! Remember, I wasn't able to saw the square tubing at 90 degrees. If you put the painted side (factory edge) up, you will not end up drilling at 90 degrees!
- Small drill bits (<3.5mm) are usually shorter. Perhaps you should make an additional, shorter guide for them?
- Even though this is made of steel, if you use it A LOT it will wear out eventually. Luckily, you still have 3 more corners that you can use!
- If you have a chop-saw or metal cutting bandsaw, you can use it to cut the top to a 45 degree angle. Now you can drill both 90 and 45 degree holes, and use it as a speed square!
- A handle. Perhaps you might want to add one?
- Clamp it down if needed. In the video, I clamped down because I needed to hole the camera, but maybe that can help in other situations too.
- And a bonus too!: It also collects the dust - no more dust everywhere!
