Cleveland C09680 31/64" Jobber Drill Bit
The Cleveland C09680 is a fractional-inch jobber drill bit sized at 31/64 inch with a decimal equivalent of .4844. It is manufactured from High Speed Steel with a steam oxide finish and a 118-degree point angle. This accessory is designed for general-purpose drilling tasks using compatible power tools.
Suited for fractional sizing and HSS durability
This bit suits machinists and maintenance personnel who require the specific 31/64 inch fractional diameter and the wear resistance of High Speed Steel. The 118-degree point angle supports standard drilling in common materials. Buyers needing a different diameter, a metric size, or a split-point geometry for self-centering should look at other options.
31/64 inch fractional diameter with 118-degree point
The decisive specification is the 31/64 inch cutting diameter paired with a 118-degree point angle. This combination determines the hole size produced and the bit's suitability for standard drilling applications in steel, cast iron, and similar workpiece materials. Verify that your application requires this exact fractional size and point geometry before purchase.

Questions about this item
Should I choose the 31/64 inch size or a different fraction for my job?
Select 31/64 inch when the hole must be exactly .4844 decimal; pick the next size up or down only if the drawing allows that tolerance.
What does the 118 degree point angle do once the bit is in the drill?
The 118 degree point centres quickly in steel and general metal without a pilot hole and gives a strong tip for handheld or press work.
How does the steam oxide finish on this high speed steel bit affect drilling?
Steam oxide holds cutting fluid better than bright finish, reducing friction and extending edge life in ferrous metals.
