296 Series High-Speed Steel Extra-Long Length Oil Hole Drill Bit, Black Oxide Finish, #3 Morse Taper Shank, Spiral Flute, 118 Degrees Notched Point, 33/64" Size, 12-1/2" Length (Pack of 1)

Michigan Drill high-speed steel extra-long length oil hole drill features coolant passages throughout the length of the body. These allow a coolant (air, oil or vapor mist) to reach the cutting edges. The resulting flow cools and lubricates the cutting edges and also aids in the extraction of chips. 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. 118 degrees notched point.
