Reviews Black Oxide Drill Bit

Cleveland 950E High Speed Steel Extra Long Length Drill Bit, Black Oxide, Round Shank, 118 Degree Notched Point, 1/2\ Dia. x 10\ Lg (Pack of 1)

Extra-long length drill bit reaches farther and drills deeper than a jobber or long length drill bit.
High-speed steel (HSS) provides hardness for wear resistance.
Black oxide finish reduces wear while promoting chip and coolant flow on ferrous materials.
Self-centering 118-degree notched point penetrates material more easily than a conventional point without a pilot hole, and maintains a sharp cutting edge.

High Speed Steel tool - 20mm cutting diameter. Good for most general purpose applications, featuring a combination of hardness and toughness for wear resistance.
Reduced Shank - Expanding the size range capacity of a portable drill chuck. Common flute and overall length for minimal adjustment during tool changes.
Black Oxide Finish - Black oxide treatment adds lubricity. Small pockets on the surface of the tool that act to hold coolant near the cutting edge.
Wide Application - Design for drilling in low and medium tensile strength materials, such aluminum, iron, copper, brass and metal.
Please Note: To make clean and precise holes, water is required for lubrication and cooling when drilling metals. Increased use of water lubrication will extend drill bit life.
