High Quality Material - High Speed Steel M2 Black and Gold, resists corrosion, ensures outstanding durability, sharpness and capability, reduces the friction and runs cooler..
Black and Gold Oxide Finish - Premium gold titanium and black nitride dual coating can apply lubricant better for smoother drilling and is more durable and corrosion resistant than the regular black surface..
135-degree & Split Point - Increases cutting speed with self-centering and prevents walking, clears chips and particles faster. The split point tip can increase the wear resistance. 135-degree penetrates hard material without a pilot hole and produces small chips to reduce clogging..
Special Design - Unique tri-flat shank and 1/2” reduced shank can lock onto chuck to permit portable drilling. The special design can drill tough and high-tensile strength materials. The bit is only suitable for portable drilling with 1 / 2 "drill chuck,not applicable to other drill chuck sizes..
General Purpose - It is ideal for drilling steel, copper, aluminum, brass, oak, maple, MDF, pine, PVC, polycarbonate, acrylic, ABS, nylon and composite materials..

Set of 15 jobber length drill bits includes inch sizes 1/16" through 1/2" in 1/32" increments.
High-speed steel (HSS) provides hardness for wear resistance.
Black oxide finish reduces bit wear while promoting chip and coolant flow on ferrous material.
118-degree conventional point for a range of drilling applications.
Jobber length drill bit has a midrange drilling depth suitable for general-purpose drilling applications.
