Chicago-Latrobe 50466 Extra Long Drill Bit
The Chicago-Latrobe 50466 is a fractional-inch drill bit sized at 9/64 in with a 118-degree notched point. Made from high-speed steel with a black oxide finish, it offers a maximum drilling depth of 9 in. The 4xD design suits general-purpose machining tasks that require extended reach.
Check shank compatibility and workpiece thickness
Verify that your drill chuck accepts the 9/64 in shank before ordering. Confirm the workpiece thickness does not exceed the 9 in maximum drilling depth. The 28-degree helix angle influences chip evacuation, so ensure your application matches general-purpose machining parameters.
Black oxide finish and notched point improve
The black oxide coating reduces friction and resists corrosion during extended use. The 118-degree notched point aids in accurate hole starts without a centre punch. These features combine to maintain cutting performance across the full 9 in depth capacity.

Questions about this item
Does the 50466 drill bit come as a single piece or a set, and is a drill chuck included?
The 50466 is sold as an individual extra-long drill bit; a compatible drill chuck is not included and must be purchased separately.
How do I choose between fractional sizes like the 9/64 inch option for this model?
Select the 9/64 inch size when your project requires that exact fractional diameter; other fractional sizes are separate items under different part numbers.
What does the 118-degree point angle mean for drilling performance in a real machine?
The 118-degree point angle provides a general-purpose cutting geometry suitable for drilling into common materials like mild steel and wood on standard drill presses or hand drills.
