Chicago-Latrobe Jobber Drill 41/64" HSS 70241

This Chicago-Latrobe jobber drill bit is made from high-speed steel with a TiN coating. It has a fractional size of 41/64 inch and a decimal equivalent of .6406 inches. The conventional point features a 118-degree angle and is designed for non-coolant-through applications.

Suited for general-purpose drilling in metal

This drill suits users who need a 41/64 inch fractional bit for standard drilling tasks. It is not for buyers who require a coolant-through design. It is also not for those who need a different point angle or a different fractional size for their specific application.

Questions about this item

Will the 118-degree conventional point on the 70241 bit need regrinding after heavy use?

The 118-degree conventional point can be resharpened on a bench grinder or drill sharpener when it dulls, restoring the original cutting geometry without special equipment.

What stops the 41/64-inch HSS bit from drilling deeper in a single pass?

The jobber-length flute limits chip evacuation depth, so the bit must be withdrawn periodically to clear swarf when drilling beyond the flute length.
