TEC 3/8" Hex Shank Drill Bit for Digital TrueFlow Testing with Hole Plugs

This drill bit is specially designed for drilling into HVAC equipment during testing with the Digital TrueFlow® Air Handler Flow Meter. The 3/8-inch diameter drill bit extends only 5/16-inch from the milled drill stop to help prevent damage to equipment contained in the cabinet. The drill bit features a 1/4 quick-change hex shank for use with a wide variety of drills and drivers. The 25 included hole plugs are the perfect size to plug holes made with the 3/8" drill bit and easy to remove for future testing.
