Chicago-Latrobe 52463 118° Drill Bit
This Chicago-Latrobe 52463 drill bit features a 118-degree point angle and a 63/64 in size. It is made from high speed steel with a black oxide finish. The 1/2 reduced shank allows use in chucks that cannot accept larger shanks. It suits general-purpose drilling in metal and wood.
Machinists needing 63/64 in holes with 1/2 chucks
Machinists who need a 63/64 in hole but only have a 1/2 in chuck capacity will find this bit suitable. The reduced shank bridges that gap directly. Buyers who need a larger shank for heavier feed pressure or a different point angle for specialised materials should look at other options.
118-degree point angle and 63/64 in diameter
The 118-degree point angle and 63/64 in diameter are the primary specifications that determine fit for the application. The high speed steel construction and black oxide finish support standard drilling tasks. Verify the required hole size and point geometry match these figures before purchase.

Questions about this item
How do I install the 1/2 reduced shank into my drill chuck, and what step is commonly missed?
Open the chuck fully, insert the reduced shank until it seats against the jaws, then tighten securely; the step often missed is verifying the shank is centred before final tightening.
What maintenance or replacement will the 118° high-speed steel bit need after extended drilling?
The black oxide finish resists wear, but the cutting edges will dull over time; plan to resharpen the 118° point angle or replace the bit when drilling performance drops.
At what point does the 63/64 in diameter bit reach its limit during sustained heavy drilling?
Heat buildup in the high-speed steel is the first limit; excessive temperature softens the cutting edges, so use cutting fluid and allow cooling breaks to maintain hardness.
