1/4 Cobalt Drill Bit Set (Pack of 12) for DIY Enthusiasts

About this item

• When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging
• Cobalt steel tools are similar to high-speed steel, but with more cobalt for improved performance when cutting harder metals such as stainless steel or nickel alloys
• Gold oxide is a thinner oxide surface treatment than black oxide typically used to identify cobalt steel tools; performance is similar to uncoated tools
• Of course! However, I need the original text you want me to modify in order to help you. Please provide the lines you'd like me to rephrase.
• Round shanks allow use with a wide variety of toolholding systems
• Manufactured to National Aerospace standard 907
