Review : Black & Decker CD70 12mm Hammer Drill
This is a Black & Decker CD70 Hammer Drill 13mm with screw driving option. It was given to me by my father. It is a DIY drill for most general purposes. It cost around INR 5500. Here is a small review of it. i have benn using it from 2 years with no problems at all.

The first thing that you notice about the B&D Unit is its build quality; a factor very important for drilling tasks. Everything about it oozes sturdiness & non-breakability. The cases (for carrying the Drill & the Drill Bits) are made of hard-plastic which makes them strong as well as resistant to scratches. It is riveted at 3 wide points so you can be sure that the pivot will hold for a really long time. The drill itself is durable enough to outlast its owner. The cord is also excellent, providing a fuse in the plug itself. They close by means of a pull-up clip. The fit/finish is also excellent with no panel gaps anywhere. It has a transparent cover on the Case Lid where you can keep the drill bits & screw heads if you dont want to carry a separate kit-box.
Now, coming to the driller itself, it is about 12in length. It has options for varying RPMs as well as reversing directions; hence it can be used as a screwdriver as well. Since it is a hammer drill, it has options for both hammering & normal drilling. The screwdriver bits have been provided in the Kit box. Altogether the driller is excellent for most practical purposes.
The kit-box contains the drill bits and the screw driver bits. It has drill bits from the thinnest to the thickest one. The screwdriver heads are present for all types, including flat, Philip (+). Exact Contents are listed below:
It was bought in New Delhi and it cost him around INR 5500 around 2 years back. I have been using it since then.
Although I tried to find negatives, I could only find two.
No second handle: For a drill that is so versatile, a second handle could have helped. Many times I have found my arm shaking wildly without a proper grip. There are places where you require a lot of grip, for ex drilling into masonry.
Adjustable depth stop: Again something which could have helped in getting the last bit of perfection that you wanted. Anyway, I guess that one cannot have anything that everyone wants.
The Directoon Selection Switch
The hammer/regular mode selection switch.

re: Review : Black & Decker CD70 12mm Hammer Drill
One of my unskilled operators unknowingly burnt the motor winding on one B&D drill trying to force the jammed machine through metal bar under RCC, smoke started billowing from the side grill at the back and the motor went kaput, the machine was replaced.
The drawbacks from my perspective are a particularly small chord for a hand tool and a plug that is designed poorly never fitting tight into any socket. In addition to lack of a quick connect chuck and the second handle as you mentioned.
Apart from that, the machine deserves to be kept busy.
