Best Heat Gun – DeWalt vs Milwaukee vs Greenworks


Trying to find the Best Heat Gun? Although not necessarily the first thing that everyone thinks of putting in their toolbox, the trusty heat gun may just become that indispensable tool you find you can’t do without and going for over and over again. Whether the project on hand is to strip paint, remove rusted bolts, or simply collapse heat shrink tubing for a wire harness, a heat gun is often the best tool for the job because of the high temperatures it can reach.

Read on to find out about the three cordless heat guns in our comparison review:

  1. Dewalt Cordless Heat Gun
  2. Milwaukee Cordless Heat Gun
  3. Greenworks Cordless Heat Gun

So what exactly are heat guns?

Heat guns are similar to hair dryers in operation.  Simply put, they use a fan for blowing air over a heated filament. They usually have controls for multiple fan speeds to adjust air velocity and a given range in Celsius or Fahrenheit for setting the temperature.  The air can also be channeled or directed in certain ways using various attachments that can be fitted on the heat gun’s output nozzle.

Cordless = Game changer

One of the things to consider when buying a heat gun is the power source. Many heat guns have a power cord that you can plug into a standard outlet. However, there are times when that standard wall outlet isn’t very close, or you can’t be bothered with extra hassle and/or hazard of an extension cord (think tripping risk, higher amp draw due to heating element, not wanting that extra cord when working on a ladder, etc.)  That’s when cordless models come into play. Take a look at a few different models and choose one that looks right for you.
