Sutton Tools Silver Bullet Panel Drills are developed to drill holes for rivets in flat and curved panels and used in sheet metal fabrication. The double ended design doubles the life of the drill bit. The 135 self centering point minimises wandering when starting making it ideal for thin materials and the flute length is designed for shallow hole drilling no deeper than 1.25mm x diameter. These are made from M2 High Speed Steel (HSS) offering the best combination of strength, heat & wear resistance and has a bright finish for general purpose applications, non-ferrous metals & plastics.
