Carlisle ST1 No. 68 Drill .031 6 Pk 336464

The Carlisle ST1 is a spray foam gun that requires periodic maintenance to ensure optimal performance. One of the maintenance tasks is to clean the mix chamber and the spray tip of the tool, which are the parts that mix and spray the foam material. The mix chamber and the spray tip have small holes that can get clogged with dried foam, affecting the spray pattern and quality. To clean these holes, the user needs to use a drill bit that matches the size of the hole. The drill bit is a metal rod with a spiral groove that can remove the clogged material by rotating. The drill bit has the part number 336464 and the size No. 68, which means it has a diameter of 0.031 inches.
