Our Drill/Tap combo bits feature a drill bit and a tap all in the same bit making it easy to drill and tap holes. They are made from high-molybdenum tool steel for high strength and long tool life and are black & gold coated for maximum lubricity. They are excellent for maintenance and repair of equipment and assembly and production environments. The drill bit features a 135* split point which allows the bit to quickly sink into hard metals and keeps it centered allowing for accurate cuts. Made in the USA by Norseman Drill & Tool.
