This Chicago-Latrobe extra long drill bit measures 45/64 in and is made from high speed steel with a black oxide finish. The 118 degree notched point and 28 degree helix suit general purpose machining. It provides a maximum drilling depth of 9 in at a 4xD ratio.

Check your setup before ordering

Verify that your drill chuck accepts a 45/64 in shank and that the machine delivers enough torque for a 9 in flute length. Confirm the 118 degree point angle matches the material you plan to cut. Buyers needing a different diameter or a shorter overall length should select another bit.
