Best Reduced Lubrication

uxcell 28mm Reduced Shank Drill Bit HSS 6542 Black Oxide with 1/2 Inch Straight Shank

High Speed Steel tool - 28mm 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.
