Frequently Asked Questions (FAQs)

1. How do you make a drill bit extension?

To make a drill bit extension, pound the hex end of a bit driver into a coupling nut that is slightly smaller than the driver. Screw the coupling nut onto a threaded rod, cutting off any excess length if necessary. Finally, chuck the rod into your drill for an extended reach.

2. What to do if my drill bit isn't long enough?

If your drill bit isn't long enough, you can use a drill bit extender. These extenders are designed to work with hex bits and can provide the extra length you need. However, it's important to note that they are not compatible with twist bits or other bits with cylindrical shanks.

3. What is the use of insert drill sleeve?

Insert drill sleeves are commonly used in orthopedic surgical procedures. They allow for accurate and precise drilling of holes. These sleeves come in different variations, with different diameters to accommodate specific screw and drill bit sizes.

4. Why use a drill bit extension?

Drill bit extensions are useful for professionals as they expand the reach and drilling capability of flexible drills. They allow for easy access to difficult and compact spaces.
