Top 10 Best 9/16 Drill Bit For Metal

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.

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.

Made of high speed steel. 6-inches overall length. 118 degree drill point. 12-inches straight shank.

Premium cobalt high speed steel construction for proven capability and durability to drill holes in wood, plastic, aluminum, copper, stainless, sheet metals and many other types of materials. Superior gold titanium and black nitride dual coating finish holds up lubricant better for smoother drilling, and is 80 more durable and corrosion resistant than regular black enamel finish. 135 Split point design at tip increases cutting speed with self-centering feature and prevents drill walking or wobbling. 12 Inch reduced shank with tri-flatted end locks onto 3-jaw power tools chuck more securely and eliminates slips. Set includes 8 pieces 6 long silver deming drill bits in a heavy duty aluminum storage case for easy carrying and organization 916, 58, 1116, 34, 1316, 78, 1516, 1.

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.

Speed helix design for three times faster drilling than standard bits. Last 50 percent longer than high-speed steel. Easier drilling, reduced heat and extended drill bit life. Available in jobber length, stubby length, extended length aircraft, 12 In. reduced shank Silver and Deming. For use in steel, copper, aluminum, brass, oak, maple, MDF, pine, PVC, polycarbonate, acrylic, ABS, nylon and composite materials.

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 12 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..

916 HSS 38IN DRILL BIT. 916 HSS 38IN DRILL BIT. 916 HSS 38IN DRILL BIT. 916 HSS 38IN DRILL BIT. 916 HSS 38IN DRILL BIT. 135 degree split point drills on contact and prevents walking. Parabolic flute design improves chip ejection in metal and wood drilling applications. Black oxide coated for greater wear resistance. Helix is 31 degrees which minimizes the over aggressiveness of a true parabolic flute.

POINT DESIGN 135 split point design increases cutting speed with self-centering feature and prevents drill bit walking or wobbling on working surface.. REDUCED SHANK with THREE FLATS 12 reduced shank drill bit with tri-flat is designed to eliminate drill bits spinning in the chuck and ensures grip. Superior black oxide finish offers great wear resistance.. WIDE FLUTE Parabolic flute design improves chips removal and prolongs drill bits life while drilling in metal and wood.. GENERAL PURPOSE It is ideal for drilling steel, copper, aluminum, brass, oak, maple, pines, PVC, ABS, polycarbonate, acrylic, nylon and composite materials.. PACKAGING 3 pcs in one package. Each drill bit is in one plastic tube, and three tubes are in one paper carton. This packaging protects drill bit well from bomping against each other and also is convienent for storage..
