About this item:

• Bordo Cobalt Tough HSS-Co5 Step Tip Extreme Performance Reduced Shank Drill.
• Super-fast drilling in ferrous & non-ferrous metals and all timbers.
• Step Tip negates the need for a pilot drill in metals and provides extreme drilling speeds in ferrous and non-ferrous metals & all timbers.
• Flatted shank ensures no chuck slip – maximising torque transfer for fast drilling.
• Cobalt HSS Twist drills are extremely hard and provide superior performance and increased tool life especially in stainless steel and high tensile steel.
• Bronze Finish (gold oxide) surface treatment. The metallic brown coloured low temperature temper treatment is normally only used on cobalt tools for identification purposes.
