Pros for the DeWalt 4.5 Inch 11 Amp Angle Grinder

  • The price level for the Angle Grinder alone is very competitive and very attractive for a tool of this quality – great value provided. Plus you have the option of going down the Grounded route or with the Kit box or with no lock and all options are generally under $100/$120 when seen at the time of this review
  • There is free shipping included here also (as the value is over $25) and you can also avail of free Amazon technical support which is a great service to have especially for newbies or inexperienced operators.
  • You will find that the dust ejection system works really well by getting rid of any damaging dust or debris particles that may enter the tool and the One Touch guard system allows for 360 degree rotations of the guard with a single action
  • It includes the disc change tool free mechanism and doesn’t need or require any wrenches and has the small grip surface which provides lots of comfort for a tool in this power class.
  • The cord length is decent at 72 inches long and you are also provided with the paddle switch with the safety lock which prevents any accidental start-ups and there is also the auto shut off brushes where the tool will shut down automatically when the brushes need to be replaced which ensures that the tool lasts longer
  • There is also a superb warranty period of 3 years from authorized sellers (plus 1 year free service/90 day money back guarantee) which gives lots of confidence when you buy and peace of mind for back up and the one touch guard works brilliantly.

Cons for the DeWalt 4.5 Inch 11 Amp Angle Grinder

  • It states that these wheels can be changed without a tool but this is easier said than done, you are better off using a hex key or spanner wrench to get the wheel changed. It is possible to change without a tool but it is a lot more difficult than expected without a tool
  • It doesn’t include a type 1 guard when cutting and there is no variable speed setting available either – just a single speed setting
  • There is a safety lock on the paddle on/off switch which may annoy some operators who tend to use the tool daily and it can be difficult to adjust when needed especially when wearing gloves
  • The cord of just 72 inches will be too short for many people and it does not include a proper guard for using a cutting wheel
  • The quick change release feature listed is not actually available which is extremely disappointing – it should be removed from the product spec as it doesn’t actually have it and creates confusion

Price Guide:

  • The price guide when last seen at the time of this review for the Angle Grinder only was in the $65 to $95 region with Amazon which of course can be double checked below

Section 4 – Conclusion & Your Feedback (optional)


Do we recommend the DeWalt 4.5 Inch 11 Amp Paddle Switch Angle Grinder DWE402? Yes, without a shadow of a doubt. The one touch guard is superb, the power and cutting is one of the best we have seen and overall this is great value for a small quality tool that will not let you down. As it is backed with the 3 year warranty, you have great confidence knowing that DeWalt will stand over their angle grinders like this and it offers more power from what we have seen when compared with the likes of other top branded angle grinders.

Many other brands require you to use a spanner and shaft wrench but here all you need is a large allen wrench for the wheel nut which is included which makes the disc changing a whole lot easier. It has a much lighter weight which reduces arm and hand fatigue and the discs can be changed without a tool or with the tool – whatever makes it easier for you and the 11 Amps gives plenty of torque – more than what you would expect but be warned that the quick change wheel release is not actually included with this model (advertised in certain places as being available) so please take note of this if this feature is important to you.

  1. Disk changing is a lot more easier with the DeWalt 4.5. I like the fact that it is all very good with only a few cons. I already had my eyes on it and having completed this post, I had great joy to see that it is your recommendation as well. I will buy this angle grinder definitely. Thank you very much for sharing your own experience as it is good to get a second opinion

  2. Hello! Excellent review you have made of this important tool the dewalt angle grinder. I just wanted to know the length of the cable and what is the diameter of the disc hole.  The money back guarantee for a period of 90 days is incredible. I am thinking of getting one and I would like to get my friend one also as he is always borrowing mine which is annoying. I will talk to him first before making the purchase. Thank you very much and I will send this page link to him to read first so that he is prepared in advance, cheers for the detail in your review
