Chicago-Latrobe 44016 Jobber Drill Bit
The Chicago-Latrobe 44016 is a jobber-length drill bit made from high-speed steel with a black oxide finish. It features a 118-degree conventional point angle and a 1/4-inch fractional size with a 0.2500 decimal equivalent. Designed for general-purpose drilling, it suits maintenance, fabrication and automotive tasks.
Suits general-purpose metal and wood drilling
This bit suits users drilling steel, cast iron, aluminium or wood in handheld or press-mounted drills. The 118-degree point centres easily without a pilot hole. Builders needing coolant-through capability, carbide tips or specialised coatings for high-temperature alloys should look at other tooling.
Black oxide finish aids chip flow
The black oxide surface treatment helps reduce friction and improves chip evacuation during drilling. It also provides a degree of corrosion protection for storage. No coolant holes or specialised coatings are included, so cutting fluid must be applied externally for demanding metalwork.

Questions about this item
What drill chuck size is needed to hold the 1/4 inch shank of this jobber bit?
A chuck that opens to at least 1/4 inch (0.2500 decimal equivalent) will grip the straight shank securely.
Will the 118 degree conventional point start cleanly in the mild steel I usually drill with older high-speed-steel bits?
Yes, the 118 degree point angle is the standard geometry for general-purpose drilling in mild steel and works the same way as older HSS bits.
How can I confirm the bit is cutting correctly once it is in the chuck?
The bit should produce continuous chips, run without excessive vibration, and leave a round hole at the 0.2500 diameter.
