The Black & Decker 18V Cordless Drill, GC019SFB, provides controlled drilling and driving thanks to its variable speed plus reverse. The stud finder detects studs through walls up to .75 inches thick. With a soft grip, there is added comfort while using the drill, and slipping is reduced. This makes the job much easier than ever before. A keyless chuck means bit changes quick and easy, while the 24-position clutch keeps screws from stripping. Whether you are looking to drive into wood, metal or plastic, this Black & Decker drill set works well. It is made of metal and plastic for durable construction.
