Cleveland 59/64 Inch HSS Jobber Drill Bit
This Cleveland drill bit is a fractional-inch cutting tool made from high-speed steel with a bright, uncoated finish. It features a 118-degree point angle and a straight shank designed for general-purpose drilling in metal and other materials. The jobber length provides standard reach for a wide range of machine shop and maintenance tasks.
Suited for general metalworking
Machinists and technicians drilling holes of this specific fractional size in steel, cast iron or non-ferrous alloys will find the high-speed steel construction appropriate. The bright finish suits applications where a coating is not required or where coolant is used. Buyers needing a coated bit for extended life in abrasive or high-temperature materials should look at alternative surface treatments.
59/64 inch diameter with .9219 decimal equivalent
The bit cuts a hole diameter of 59/64 inch, which is .9219 in decimal form, offering precise sizing for clearance or tap drill requirements. High-speed steel provides sufficient hardness for standard drilling speeds in ferrous metals. The 118-degree point centres well but may walk on very hard or angled surfaces without a centre punch or pilot hole.

Questions about this item
What chuck size is needed to hold the 59/64" straight shank?
A chuck that opens to at least .9219" (59/64") is required to grip the straight shank securely.
Can this 118-degree HSS bit drill into hardened steel that older carbon-steel bits cannot?
High-speed steel with a 118-degree point handles harder materials better than carbon steel, but very hard steels may still need cobalt or carbide.
How can I confirm the bit is cutting correctly after I start drilling?
Look for continuous, straw-coloured chips and a steady feed; blue chips or chatter mean the bit is dull or the speed is wrong.
