The Kobalt KWT-2100 is another excellent option. It’s cheaper than the Bosch, but it’s not quite as durable.

The tool still gets the job done, however. The Kobalt is lighter than the Bosch. It also is a great option for people that prefer to work without tools.

We highly recommend the Bosch GDS18V-221. It’s more durable and more reliable than the Kobalt KWT-2100. The tool also feels more comfortable and balanced in your hands. All in all the tool is just better than the Kobalt KWT-2100 in every way.
