Combination Drill & Thread Mills, Thread Size: 7/16-20 , Finish Coating: Titanium Diboride MPN:820676-C8

Combination Drill & Thread Mills are versatile cutting tools that can bore, thread, ream, and counterbore holes of different shapes in metal materials such as steel, aluminum, titanium, cast iron, bronze, and brass with an extensive thread size range (3/8 to 1-20). Designed with precision, hardness, and durability in mind for prolonged usage, they have become an essential component within the machine shop environments as well as automotive garages where high levels of quality, repeatable accuracy, and speed is demanded. Thread Mills come equipped with titanium diboride coating (TiAlN), which offers a unique combination of lubricity, heat and abrasion resistance, enabling the user to produce accurate threads at fast feeds and speeds while preventing chipping, built-up-edge formation or material galling on internal, external or through-hole applications. Overall, these Combination Drill & Thread Mills improve user's productivity by decreasing set-up times with minimal changeover required when transitioning from drilling to thread milling operations for multiple part sizes in various materials.
