Top 10 Best 5/8 Drill Bit

Constructed of M-2 high speed steel for the best combination of strength, heat resistance, and wear resistance. Standard 118 degree point. for use in wood, metal, and plastic.

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. Round shanks allow use with a wide variety of toolholding systems. When run in a counterclockwise direction right-hand cut spiral fluted tools evacuate chips up and out of the cut to reduce clogging. Manufactured to National Aerospace standard 907.

High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance. Black oxide treatment adds lubricity and creates small pockets on the surface of the tool that act to hold coolant near the cutting edge. Round shanks allow use with a wide variety of toolholding systems. When run in a counterclockwise direction right-hand cut spiral fluted tools evacuate chips up and out of the cut to reduce clogging. Ideal for drilling in low and medium tensile strength materials.

High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance. Gold and black surface treated for use in stainless steel and other hard metal drilling. Round shanks allow use with a wide variety of toolholding systems. When run in a counterclockwise direction right-hand cut spiral fluted tools evacuate chips up and out of the cut to reduce clogging. Heavy duty 135 degree split point.
