Chicago-Latrobe 53144 Drill Bit
This Chicago-Latrobe 53144 drill bit is a general-purpose cutting tool designed for machinists and maintenance technicians. It is manufactured from high speed steel to provide a balance of hardness and toughness for standard drilling operations. The taper shank design allows for direct mounting into compatible machine spindles or sleeves. It suits workshop tasks requiring a reliable 11/16 inch hole diameter.
11/16 inch capacity and application limits
The bit drills a precise 11/16 inch diameter hole suited for general-purpose metalworking in ferrous and non-ferrous materials. Its high speed steel construction offers adequate wear resistance for moderate production runs and maintenance work. The tool runs out in high-volume production or when drilling abrasive alloys that demand cobalt or carbide substrates for extended life. It is not for buyers who need larger diameters or specialised coatings for exotic materials.
118 degree conventional point geometry
The 118 degree conventional point angle is the critical specification determining suitability for standard drilling tasks. This geometry centres easily without a pilot hole and performs reliably across common steels and cast iron. A different point angle would be required for hard materials or deep-hole drilling where chip evacuation and thrust force differ. The black oxide finish adds lubricity and corrosion resistance during use.

Questions about this item
Will the 11/16 in taper shank fit directly into my older drill press spindle without a sleeve?
The 11/16 in drill bit uses a taper shank designed to seat in a matching Morse taper socket; check your press spindle taper size to confirm direct fit.
How can I confirm the 118 degree point is cutting correctly after installation?
A properly sharpened 118 degree conventional point produces clean, centred holes with minimal wander and consistent chip formation in steel.
Does the 53144 package include any cutting fluid or only the high speed steel bit?
The box contains the single black oxide high speed steel taper shank drill bit; cutting fluid or coolant must be purchased separately.
