• High Speed Steel tool - 14mm cutting diameter. Good for most general purpose applications, featuring a combination of hardness and toughness for wear resistance
• 1/2 Inch Reduced Shank - Expanding the size range capacity of a portable drill chuck. Common flute and overall length for minimal adjustment during tool changes
• Black Finish - Black nitride coating increases hardness and wear resistance, allowing it to maintain its sharpness and cutting efficiency longer, and also provides corrosion resistance. 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
