How To Use An Allen Wrench With A Drill?

If you’re enthusiastic about mechanics, then it’s likely that you’ll know about Allen wrenches. They are a simple tool that is very useful in experienced hands. This L-shaped metal tool is an effective way to produce a significant amount of torque.

They have a hexagonal cross-section to fit into different variations of machine screws and set screws with hexagonal recessed holes. You may not know that you can actually integrate an Allen wrench into a cordless drill for extra power.

This guide will tell you exactly how to do this, as well as the different types of Allen wrenches available and their uses.

What Is An Allen Wrench?

The Allen key is a small hand tool with a hexagonal socket for driving bolts and screws. Each one of them has a tip with a hexagonal shape and comes in various different sizes. The fastener could be harmed if the incorrect hex key size is attempted.

How To Use An Allen Wrench With A Drill?

Using an Allen wrench by hand can be difficult and slow when used in bigger, more complex projects. To make it easier, you can convert an Allen wrench into a drill bit to give it extra power. To do this, you will need an Allen wrench, a pair of pliers, and some bolt cutters.

  1. First, grip the L-bottom part of the Allen wrench firmly with a pair of pliers.
  2. Next, you’ll need to remove it. Using your bolt cutters, cut the wrench at the bottom of the long side L-shape. Even out your cut so that there is a flat, even surface to insert into the power drill.
  3. Finally, insert the cut Allen wrench into the nose of the drill and lock it into place. 
  4. Make sure you test the efficiency of your newly integrated tool and see if it stays intact before using it.
