This review is from: Irwin 39109 9/16-Inch by 18-Inch Installer Twist Drill Bit (Tools & Home Improvement)

I've been using these for years in the satellite tv, alarm, and the electrical industry. The 18" length is just ideal for drilling from outer walls into the interior, through top and bottom wall plate studs into walls. These are fast drilling and long lasting. I have them in 1/4, 5/16, 3/8 and 1/2" diameters. The 5/8's will be ideal for standard sheathed cable.

Just ordered two more.

This review is from: Irwin 39109 9/16-Inch by 18-Inch Installer Twist Drill Bit (Tools & Home Improvement)

I needed to run cat-5 cable (for the computer) from the first floor to the second floor of my house (*shakes fist at Vista's wireless issues*). The 9/16-inch bit was just the right size to make a hole for the cable and the length of the bit was plenty to make it through the floor.
