Chicago-Latrobe 54065 Cobalt Jobber Drill Bit
This Chicago-Latrobe 54065 jobber length drill bit is made from cobalt steel with a titanium nitride coating. It features a 135 degree split point for accurate starts and reduced walking. The fractional size is 23/64 in with a decimal equivalent of .3594. It suits general purpose drilling in metal, wood and plastic.
For machinists and maintenance crews drilling
The bit is designed for jobber length applications and non coolant through use. It has zero coolant holes and a standard shank. Buyers needing coolant fed drilling or extra long reach should look at other tooling. The split point geometry helps in handheld and machine use alike.
23/64 in fractional size with 135 degree split point
This single specification determines fit for the required hole diameter and start quality. The .3594 decimal equivalent matches the fractional callout exactly. Cobalt construction with TiN coating supports longer life in ferrous materials. Verify the drill chuck capacity and workpiece thickness before purchase.

Questions about this item
What size drill chuck is needed to hold the 23/64 in shank?
A chuck that opens to at least 0.3594 in (23/64 in) will grip the bit securely.
Will the 135 degree split point start cleanly in steel hardened by older high-speed bits?
The 135 degree split point is designed to self-centre and reduce walking in hard materials such as work-hardened steel.
How can I confirm the TiN coating is intact after the first few holes?
The cutting edges should retain a gold-coloured finish; loss of that colour on the lips indicates the coating has worn away.
