Comparison of Dewalt DCD771C2 with other similar cordless drills

Dewalt DCD771C2 vs Dewalt DCD777C2

Although the model numbers are quite similar, these two cordless drills have features that are quite different. The first major difference I would like to discuss is the motor quality.  DCD777C2 has a superior brushless motor while the counterpart has a regular motor. A brushless motor runs more smoothly and consumes less power. Therefore, DCD777C2 will have at least 30 percent more runtime. The wattage of this model is 200 that is around 33% less than that of the counterpart. But the torque you get from these two is almost the same.

The weight and dimension are other differentiating features of these two models. The weight and dimension of DCD777C2 are 2.6 lbs and 12.5 x 3.75 x 9.81 consecutively. Therefore, it is lighter and smaller than the counterpart. If you are counting on portability and compactness, then I would recommend you Dewalt DCD777C2.

Because of the better-quality motor and compact feature, DCD777C2 has a higher price tag that is justified. All other features of these two cordless drills are quite similar. Both of the models have lithium-ion batteries, they produce almost the same amount of torque and speed. Therefore, in terms of application, both are almost equal.

Dewalt DCD771C2 vs Dewalt DCD708C2

There are few major differences between DCD771C2 and DCD708C2 models of the Delwat cordless drill. Motor quality is the major difference I would say. For example, DCD708C2 has a brushless motor which creates more torque and speed. The motor power of DCD708C2 is 340 that is also higher as expected. As the motor quality is better, DCD708C2 has a higher price tag as well.

Other than the motor and the subsequent torque and speed, DCD708C2 weighs more than the DCD771C2 model. The weight of this unit is 5.6 lbs. It is almost 60 percent heavier than the other. Therefore, weight is a concern for you, then you should go with the 771C2 model.

Other than these, both of the cordless drills have keyless chuck having a dimension of ½ inch. Both of the drills will give you the same accessories. They come with 2 good quality lithium-ion batteries. Finally, if you intend to use the drill for heavy projects, then the 708C2 model is preferable. Otherwise, for regular residential jobs, 771C2 is quite sufficient.

Dewalt DCD771C2 vs Dewalt DCD791D2

Dewalt DCD791D2 is a far better cordless drill if we compare it with the DCD771C2 model. When it comes to the point of motor, then DCD791D2 has a superior brushless motor that produces less noise and gives higher runtime. Although both of the drills have two different gear settings, DCD791D2 produces higher speeds as expected. It can produce a maximum of 2000 rpm at no load.

The power rating of the DCD791D2 cordless drill is 460 where the counterpart has only 300. Therefore, it can produce higher torque and therefore, capable of handling heavy-duty operations. Although both of the models have an inbuilt LED light, the light of the DCD791D2 model is far brighter. Both of the models have almost similar weight. But the dimension of DCD791D2 is far more than the DCD771C2 model. Therefore, it is not good for portability and is not considered as compact. Another important difference between these two models is the battery capacity. Dewalt DCD791D2 has batteries with 2.0 AH capacity where the counterpart has only 1.3 AH. Therefore, it is expected that the D2 model will run much longer.
