Bosch PS21-2A Review

Bosch PS21-2A 12-Volt Review

The Bosch PS-21-2A is a quality, lightweight, super screwdriver.

It is an updated version of the Bosch PS-21, and includes a lot of improvements to the design from that older model.

In one short statement, this screwdriver is awesome.

It allows you to drive screws into just about anything and do some light to medium duty drilling as well.

It is a great companion to a powerful cordless drill.

This Bosch also is quick to recharge, and for all these reasons, it earns a high rating! Check out more details below!

  • Universal bit holder makes switching simple
  • Variable speed gives you maximum control
  • Long battery life & quick charges keep you working
  • Lightweight and powerful enough for professionals, but easy enough for anyone to use
  • Worklight and battery life has improved greatly from the previous model

Reviewers really love this drill. At the time of writing, just the Amazon reviews contained over 100 reviews with an average rating of 4.5 stars!

Though this Bosch tool is technically only a screwdriver, many reviewers report it being able to drill, and the weight/size are benefits to fall in love with. There weren’t very many negative reviews on this product, and it really shines in all but the heaviest duty circumstances.

On the negative side of life, there was one main complaint – the bit holder isn’t magnetised and can drop bits. However, if you want your magnetized, check out this video for instructions. Magnetizing a piece of metal like this bit holder is actually really easy, and all you need is a strong magnet!

The only other negative we’ve found is that the LED worklight doesn’t stay on after you let go of the trigger.

This is typical for most cordless drills, but the similarly priced and featured Makita FD01W has an exceptional worklight that stays on for a few seconds, and is definitely a tool worth checking out for just a few dollars more!

Overall, it’s a great driver that deserves it’s 4.5 stars and is worth it’s $100 price tag. Buy it now on Amazon!

Ease Of Use and Feel

Ease of use and feel is what reviewers absolutely LOVE about this drill! The Bosch PS-21-2A is lightweight, compact, comfortable and has a ton of power!

Reviews said that it is a great relief to use this tool for their screwdriving and bolting needs, because it is so lightweight compared to a full-size drill!

This drill is very simple to use. It features a 1/4″ quick change bit holder which allows you to use a variety of bits and bit sets designed for impact drills. Reviews mentioned that the power behind this drill made it necessary to buy quality bits, such as this set by Bosch.

Special Features

Where do we even begin? The PS-21-2A is loaded with really great special features, including that great LED worklight and comfort grip. It’s small size relieves the need for a belt clip, as this tool can slip right into your pocket!

Target User

The PS-21-2A is the perfect cordless screwdriver/miniature drill for anyone. Though it is probably more powerful than the average homeowner needs, reviewers stated that this Bosch is incredible for tasks around the home.

It’s very odd to see a drill that both homeowners and pro’s love, but this Bosch is an exception!  

Professionals are even more impressed and state that this is more than just a cordless screwdriver, as it can drill holes and sink long screws.

Of course, the price isn’t totally homeowner-friendly, but if you’ve got the bucks,it’s a amazing cordless driver/drill.
