Cable Tv Installers Use A Long Drill Bit That The Cable Attaches To And Follows The Bit Through The Floor Or Wall.what Is The Tool Called And Where Can I Purchase One?

I've seen thoses bits in the electrical section of Lowe's. They come in different lenghts and size.

Major brand name is D'Versa-bit. Greenlee has a version also. Also need the hand jig to work and aim the bit.
