Descriptions

• Sutton Tools Heavy Duty Cobalt panel drills have been developed to drill holes for rivets in flat and curved panels and used in sheet metal fabrication
• The 5% cobalt formula improves abrasive & heat resistance, for tougher materials such as stainless steel
• The double ended design doubles the life of the drill bit

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
• Double ended design increases drill life. Ensure that the chuck jaws are fully tightened
• Made from HSS Co. The 5% cobalt formula improves abrasive & heat resistance, for increased strength at higher cutting temperatures
• Colour Tempered surface finish enables identification of cobalt tool material
