Product Identity
This Chicago-Latrobe 44241 jobber drill bit is a fractional-inch cutting tool sized at 41/64 inch with a decimal equivalent of .6406. It suits maintenance technicians and machinists who need a general-purpose bit for drilling mild steel, cast iron or similar ferrous materials.
Setup Check
Confirm your drill chuck accepts a straight-shank bit of this diameter and that the machine delivers adequate torque at the correct speed for high-speed steel. The 118-degree conventional point requires no pilot hole but does demand rigid workpiece clamping to prevent wandering on hard surfaces.
Build & Daily Use
The bright uncoated high-speed steel construction resists heat during dry cutting because the design includes zero coolant holes. Expect reliable chip evacuation in through-holes up to standard jobber depth, though the lack of coating means more frequent resharpening compared with treated alternatives.

Questions about this item
Does the Chicago-Latrobe 44241 drill bit come individually or in a set, and is a drill chuck included?
The Chicago-Latrobe 44241 is sold as a single jobber-length drill bit. A compatible drill chuck or power tool is not included and must be supplied separately.
How do I know the 41/64 inch size with 0.6406 decimal equivalent is the right capacity for my hole?
Choose the 41/64 in size when your drawing or fastener specification calls for a 0.6406 inch diameter hole; the fractional and decimal figures are two expressions of the same drill-bit diameter.
What does the 118-degree point angle mean for everyday drilling in steel or wood?
The 118-degree conventional point on this high-speed-steel bit is a general-purpose geometry that centres easily and cuts cleanly in mild steel, aluminium and wood without specialised pilot holes.
