Review Summary:

A right angle drill certainly isn’t among tools that you’re likely to find in most toolboxes. Its purpose is to access spaces that are tight and hard-to-reach and is invaluable for jobs such as carpentry or plumbing. When one has to do some drilling in a place that’s inaccessible to a standard drill, using the right angle model is the correct choice.

Designed for heavy-duty jobs, the DeWalt DW120K is bound to help you in such situations – it’s a durable and powerful unit manufactured by one of the world’s most famous manufacturers of power tools.

In this review, we’ll take a closer look at this unit and analyze its value for the money by going over its features, pros, and cons. We’ll check out the model’s design and power, and thoroughly inform you about the unit’s signature features and perks.


  • Weight – 9.75lbs
  • Dimensions – 4.5″ x 11″ x 24″
  • Chuck Size – 1/2″
  • Motor Power – 7 AMP
  • Voltage – 110 volts

Dewalt DW120K – The Basics

The fact that this model is the real deal is noticeable right out of the box. It sports a highly-durable build quality, having a housing made from heavy-duty die-cast metal that protects the unit’s vital parts from mechanical damage. It has the weight and size that’s similar to other right angle drills made by the same manufacturer, making it not-so-portable but still quite easy to handle and operate.

One of the model’s primary selling points is the outstanding versatility. The device features three speed ranges, allowing the user to use the appropriate speed for the task at hand. Its 360° right angle attachment makes even the tightest spaces completely accessible and increases the productivity, while the 5-position side handle provides improved control. It’s a thoroughly impressive drill – let’s take a closer look at its features:

The Features


The Design

Like we said, one of the best things about DeWalt DW120K is that it features a great build quality. The model is composed of die-cast metal, putting the device into the category of premium right angle drills. This housing is guaranteed to protect the vital components from mechanical damage and something we expected due to model’s high price.

Even though it weighs close to 10 pounds, handling the DW120K is a breeze thanks to the presence of a 5-position handle. It allows the user to cater his grip to the most comfortable position for the particular application. Whether you’re drilling through the sub-floor or through the studs, you can simply adjust the handle and move comfortably and quickly through the work.

The model sports a forward & reverse switch right above the trigger. Using it is seamless, as one can easily access it with either the pointer finger or the thumb.


The DW120K comes with the standard 7 AMP motor that can be used in three different speed settings – 400, 600, and 900 (max) RPM. As you can already guess, this provides the user with a chance to always use the appropriate speed for the task at hand and makes the drill incredibly flexible. The triple gear reduction, on the other hand, is there to reduce the gear stress and provide increased torque, allowing one to use this unit even for the heavy-duty drilling jobs.

Accessories & Warranty

Along with the drill, the package also includes a convenient plastic toolbox, a side handle, an Allen wrench, as well as the chuck key and a holder. The unit comes with three years of limited warranty, one year of a service contract, and 90-days money back guarantee.

Things we liked about it

This right angle drill had us impressed right from the beginning. The first thing we noticed about it is its heavy-duty housing, which is something we deem as a must-have on the drills in this price category. It’s sturdy and robust and guaranteed to protect the motor from damage that might occur due to accidental falls.

The DW120K is also a highly flexible and versatile device, as it allows the operator to adjust the speed and complete the tasks faster and easier. We also liked the presence of the triple gear reduction, whose job is to provide the unit with a longer lifespan by protecting the gears.

Handling the device is another thing that deserves praise – the 5-position handle makes sure of that. It will allow plumbers, woodworkers, electricians, and HVAC installers to use this drill in a way that doesn’t induce cramps after only a few minutes of work.


Things we didn’t like

Like we said, this model belongs in the category of premium right angle drill drills, and as such sports an appropriate price. Unfortunately, this will make it unavailable to a large number of handymen – those with tighter budgets will have to look elsewhere.

Our only other complaint is that the adjustable angle end tends to get loose from time to time. For that matter, we advise you to make sure to get it adequately tightened before each use.

General Impressions

The users deem the DeWalt DW120K as an “ideal tool for a lot of jobs around the house.” It has received universal acclaim from both the professional contractors and the DIY hobbyists, as it sports enough flexibility to be used by both of these two groups.

Consumers are pleased with the drill’s build quality and excellent performance, as well as with the included accessories and the 3-year warranty. Some have already drilled hundreds of holes with it and are planning to recommend it to their friends and acquaintances.


Those looking for a professional-grade right angle drill should definitely consider DW120K for purchase. It’s a heavy-duty unit with the outstanding construction quality and can be used for a myriad of drilling jobs. It’s guaranteed to make your life easier when it comes to drilling in confined spaces, and as such deserves our sincere recommendation.
