Chicago-Latrobe 44020 Jobber Bit

The Chicago-Latrobe 44020 is a 5/16 inch jobber length drill bit made from high speed steel. It features a conventional 118 degree point angle and a black oxide finish. This fractional inch bit suits general purpose drilling in metal, wood, and plastic for trade professionals and serious DIY users.

Installing and using the bit

Secure the 0.3125 inch shank firmly in a three jaw chuck or collet before starting the machine. Apply steady pressure and cutting fluid when drilling steel to prevent the high speed steel tip from overheating. The 118 degree point centres well but can wander on curved surfaces without a centre punch mark.

Check your drill and workpiece

Verify that your drill chuck capacity accepts a 5/16 inch shank diameter before ordering. Ensure the workpiece material is compatible with high speed steel and that you have adequate clearance for the jobber length flute. This bit has no coolant holes, so external lubrication is required for deep holes.
