Descriptions

• Sutton Tools Blue Bullet panel drills have been developed to drill holes for rivets in flat and curved panels and used in sheet metal fabrication
• The blue finish reduces chip build up on the cutting edge and is a better choice when drilling ferrous materials

Features

• 135° self-centering point minimizes wandering when starting and ideal for thin materials
• Flute length designed for shallow hole drilling no deeper than 1.25mm x diameter
• Made from M2 High Speed Steel (HSS) offering the best combination of strength, heat & wear resistance
• Blue surface finish for ferrous applications. The steam oxide finish prevents chip build-up on the cutting edges and reduces cutting friction, especially in low carbon steels
