• Core drill with taper shank for enlarging pre-drilled or cast holes in a wide range of materials
• 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
• Morse taper shank allows the tool to be inserted directly into the machine's spindle to facilitate high torque applications such as large cut diameters
• When run in a counterclockwise direction (right hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging
• The A130 morse taper drill is especially suited for machine use and especially for column drilling machines
• Accurately ground from high quality high speed steel makes this a robust all rounder
• This specimen is steam relieving, which results in better retention of the cutting oil
