Drillco Nitro Series 400N 1/16" - 1/2" X 1/64ths Black/Gold Finish Jobber Length Drill Bit Set with straight shank is made of high-speed steel that provides long durability when drilling hard materials. Drill bit with spiral flute has a 135 split point that helps to penetrate hard materials without a pilot hole and produces small chips to reduce clogging. It is recommended for use in stainless steel and other hard metal drilling. It increases hardness for drilling stainless steel and other hard metals. It resists corrosion and increases the hardness of the drill bit for additional wear resistance. Spiral fluted tool eliminates the chips and reduces clogging. It is suitable for most general-purpose applications, offering a combination of hardness and toughness for wear resistance. It conforms to ANSI specifications.
