Frequently Asked Questions (FAQs)
1. Do drill bit extensions work?
Yes, drill bit extensions are effective tools that allow you to extend the reach of your drill. They are particularly useful in situations where the drill cannot fit into narrow spaces or when you need to reach deep holes. However, it's important to note that drill bit extensions only work with hex bits and not with twist bits or other types of cylindrical shanks.
2. Why use a drill bit extension?
A drill bit extension is used to expand the reach and maximize the drilling capability of flexible drills. It is designed for professionals and allows for easy access to difficult and compact spaces. With an ideal shank diameter and overall length, a drill bit extension enhances performance and makes drilling in tight areas more convenient.
3. What to do if your screwdriver is too short?
If your screwdriver is too short to reach a deep hole, you can use a simple solution. Create a slot in the bottom of the bit and use a flat screwdriver. This will allow you to extend the reach of your screwdriver and effectively remove screws in deep holes.
4. How do you make a drill bit extension?
To make a drill bit extension, you can pound the hex end of a bit driver into a coupling nut. The coupling nut should be slightly smaller than the driver, and you can squash it in a vise if it's too big. Screw the coupling nut onto the end of a threaded rod and saw off any unnecessary length. Finally, chuck the rod into your drill, and you'll have a homemade drill bit extension.
