Extra Long Drill Bit 23/64 in HSS
The Chicago-Latrobe extra long drill bit targets machinists and maintenance crews who need to reach deep holes in steel or cast iron. Its 23/64 inch fractional size and 118 degree notched point suit general-purpose drilling on manual or CNC equipment. The 50520 model delivers the length required for through-hole work in thick plate or structural sections.
High Speed Steel Construction with Black Oxide
High speed steel body and black oxide finish resist wear and reduce galling during extended cuts. The 28 degree helix and 4xD proportion promote chip evacuation at the 5 1/2 inch maximum drilling depth. Users who need coolant-through capability or a split-point geometry for harder alloys should select a different tool.
