33/64 inch Extra Long Drill Bit

The Chicago-Latrobe 50580 is a high-speed steel drill bit designed for deep-hole drilling tasks. Its 118-degree notched point angle suits general-purpose machining across various materials. The extra-long body provides a maximum drilling depth of 7 1/2 inches for extended reach applications.

Check Chuck Capacity and Workpiece Thickness

Verify that your drill chuck accepts a 33/64 inch shank before ordering. Ensure the workpiece thickness does not exceed the 7 1/2 inch maximum drilling depth. Confirm the 118-degree point angle matches the material hardness you intend to machine.

High-Speed Steel Construction

The high-speed steel body offers durability for general-purpose use while the black oxide finish adds corrosion resistance. A 28-degree helix angle supports standard chip evacuation during deep drilling. The fractional inch sizing ensures compatibility with imperial tooling systems.

Questions about this item

Does the 50580 bit arrive alone or with a case and any accessories?

The 50580 is supplied as a single extra-long drill bit; no case, index or additional accessories are included.

How do I know the 33/64 inch size is the right one for my job?

Choose the 33/64 inch bit when the hole diameter must match that exact fractional size; the 118-degree notched point and 7 1/2 inch depth capacity suit general-purpose machining in that diameter.

What does the 118-degree point angle mean when I am drilling?

The 118-degree notched point centres quickly in steel and other general-purpose materials, reducing wander at the start of each 7 1/2 inch deep hole.
