Drill/Driver 101: How to Use a Transmission Switch

From our Tool School series: Pro tips on choosing the right speed for properly sinking screws and drilling holes

In the second Drill/Driver 101 video, This Old House contributor Mark Clement shows you how to set the transmission switch on LOW to gain more control when getting a screw started and finishing it off at the correct depth. Higher settings are handy for countersinking, drilling small holes, and completing bigger jobs quickly—but at the risk of more mistakes.

Learn how to:
• Set the correct drill speed for your project
• Get better control with a lower speed setting
• Use high speed for smaller-diameter holes
