About this item

• Round shanks allow use with a wide variety of toolholding systems
• Manufactured to National Aerospace standard 907
• 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! Please provide the lines you'd like me to modify, and I'll help reword them while maintaining their original meanings.
• 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
• When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging
