How to Strip Wire With a Drill (6 Steps and Tricks)

By the end of this article, you’ll understand how to Strip Wire with a Power Drill.

As an electrician, I use power drills daily and occasionally to strip wires, so I have some experience that I can share with you. You can mount a wire stripper on a power drill and strip multiple wires at once to get finely stripped surfaces. Functions like speed control, torque, and reverse allow you to fine-tune the settings for optimum results.

To strip the insulation coating of your wires with a wire stripper mounted on a power drill:

  • Install the correct size wire stripper on the power drill
  • Turn on the power drill and place it on a sturdy working table
  • Grab the wires with a pair of body pliers
  • Feed the wires in the spinning wire stripper
  • Allow the stripping to run for a few seconds and then withdraw the wires
  • Adjust the rotation speed via the speed control or the torque and repeat the process if you are not satisfied with the first attempt

More detail below.

Getting Started

What You Need

Gather the following equipment.

  1. Power drill
  2. Several wires – different gauges
  3. A compatible wire stripper
  4. A pair of pliers

What Wire Stripper to Use with Your Power Drill

Fetch the correct size wire stripper compatible with your power drill.

You can get them in a local store or on Amazon. Most wire strippers useable on a power drill cost about 6$. The type, quality, and size of the wire stripper will influence the cost appreciably.

Follow the steps below to strip your wires with a power drill.

Step 1: Insert the Wire Stripper Into the Power Drill

To fit a compatible wire stripper in a power drill:

Position the power drill properly and fit the wire stripper in the chuck. Secure it by regulating the chuck. You may use an Allen wrench to tighten or lose the chuck until you achieve the best setting.

Step 2: Turn on The Power Drill

When you turn the drill on, make sure you keep the power drill on a sturdy and well-leveled working table. (1)

Caution:

The spinning section (wire stripper) is sharp. Also, handle the drill bit carefully to avoid horrible accidents.

Step 3: Grab the Wires with a Pair of Pliers

Any pliers can do just fine. Go ahead and gran single-stranded wires with pliers about five of them. You may hold the drill bit with a free hand or hold the pliers with both hands.

Caution:

Single-stranded wires are delicate. The power drill may shred them. However, if you feed the wires into the drill with precision, you will get good results.

Step 4: Feed the Wires Into the Power Drill

Now, carefully feed the wires into a spinning drill. It will take only a few seconds for the power drill to strip the insulation coating of the wires.

Also, be careful not to strip the wires beyond the required length – 1/2 to 1 inches is already enough conductive surface for most connections. To ensure you strip only appreciable depth, grab the wires (with pliers) close to the end so that only a few inches are fed into the power drill.

Step 5: Adjust the Wire Stripper Openings

Use the shaft on the stripper to adjust the wire stripper. Note that a setting that’s too tight might not give the best result. So, try to readjust it and repeat the wire stripping process.

Step 6: Strip Another Set of Wires

Like before, grab another set of wires; this time, try fewer wires (maybe two instead of 5), light up the power drill, and feed the wires into the spinning opening section on the wire stripper.

Allow a few seconds and retrieve the wires. Check the texture of the stripped sections. If you are satisfied, maintain the settings and strip all your wires. If not, consider resetting the spinning speed on the power drill. You can reset the rotation speed of the wire stripper via the torque function or speed control trigger. The torque is also known as a clutch. However, not all power drills have this feature. It’s best to purchase one with a clutch application.

Advantages of Using Power Drills to Strip Wires

Using a power drill to strip the insulation coating of wires is probably the best method after the manual one.

The Process is Fast

Once your settings are optimal, you will take only a few seconds to strip a bunch of wires. At optimal settings, you will also get the best texture of conducting surface.

Less Energy is Required

The machine will do the job for you. You don’t need to apply pressure as you would do on a regular wire stripper.

Disadvantages

Well, there are also some setbacks to using this technique to strip the insulation coating of wires. (2)

Potential Accidents

The tool may cut your fingers if handled recklessly or due to a malfunction. Handle the power drill cautiously.

Over-Stripping the Wires

Failing to withdraw the wires in time may lead to over-stripping the insulation sheath. The power drill spins very fast, and any retrieval delay may cause the wire stripper to eat away both the sheath and the actual wire.
