【Material】- High speed steel 6542 is designed to ensure sharp and fast execution in metal surface for clean results;14mm cutting diameter. Good for most general purpose applications, featuring a combination of hardness and toughness for wear resistance
【Advantage】-Expanding the size range capacity of a portable drill chuck. Common flute and overall length for minimal adjustment during tool changes
【Special Design】-Black oxide treatment adds lubricity. Small pockets on the surface of the tool that act to hold coolant near the cutting edge
【Wide Applications】- Design for drilling in low and medium tensile strength materials, such aluminum, iron, copper, brass and metal
