Tool Time was the fictitious handyman show-within-a-show in the television situation comedy, Home Improvement. It was hosted by Tim "The Tool Man" Taylor (played by Tim Allen) and Al Borland (played by Richard Karn). The sponsor of Tool Time was Binford Tools, a fictitious tool manufacturing company. The show was said to be played on channel 112.

Part of the show's attraction was its token "Tool Time girl", whose primary roles were to look good, be curvaceous, roll out various props and help introduce the two hosts. In the first two seasons, Pamela Anderson played Tool Time girl Lisa. When Pamela left the show, Debbe Dunning stepped in as her replacement, Heidi, who stayed until the show's cancellation.

During Tool Time, the hosts would teach audiences about home repair and renovations. However, Tim was more inclined to joke around, especially about Al's overweight mother and his affinity for wearing flannel shirts. Al would attempt to continue the show in a proper manner. Invariably, whenever Al was about to demonstrate the use of a particular machine, Tim would bring out his own version of the same machine that had been rewired for more power. The new machine would then backfire and cause the accidents for which Tim became famous. Sometimes, the accidents were not caused by overpowered machines but by Tim's negligence for safety precautions, though occasionally, the producers would surprise the viewers by Tim's overpowered machine actually working or Al being the one who makes the mistake.

Tim often mentioned his current off-screen problems during the show. If he had an argument with his wife Jill (Patricia Richardson), he would find an excuse to bring up the subject of the argument on Tool Time even if it had nothing to do with home improvement, much to Al's chagrin. In many episodes of the show, he also used this time to apologize to Jill in a subtle way.

Tim would at times say something offensive to a certain group on the show to which Al would respond by reciting the show's mailing address:

The audience for Tool Time was the actual live studio audience for Home Improvement. Before "Tool Time" starts, Al and Tim's humorous conversation is pre-recorded.

Guests on "Tool Time" included a group of construction workers who started a band featuring music played on tools (the "boys from K&B Construction"), racecar drivers Mario Andretti and Michael Andretti, Evander Holyfield, Grant Hill, the crew of the Space Shuttle Endeavour mission STS-61, and real-life home improvement host Bob Vila, portrayed as Tim's arch rival and Al's idol.
