Chicago-Latrobe #43 Jobber Drill Bit
This Chicago-Latrobe drill bit is a #43 jobber length bit made from high speed steel with a black oxide finish. It features a conventional 118 degree point angle and a decimal equivalent of 0.0890 inches. The bit is designed for general purpose drilling applications.
Suited for general purpose drilling in metal
This bit suits users needing a specific #43 wire gauge size for precise hole drilling. It is not intended for buyers who require coolant through capabilities or bits with specialized coating technologies. Those needing different diameters or point angles should look at other options.
118 degree point angle for general use
The 118 degree conventional point angle determines suitability for standard drilling tasks across common materials. This angle provides reliable centering and chip evacuation for general purpose work. Match the point angle to your specific material and drilling requirements for best results.

Questions about this item
How do I install the #43 jobber drill bit in my drill chuck, and what step do people often get wrong?
Insert the shank fully into the chuck jaws, then tighten securely; the common mistake is not seating the bit completely, which causes run-out and premature wear.
What maintenance or replacement will the #43 HSS drill bit need after extended use?
The black oxide coating on the high speed steel will wear away; resharpen the 118° conventional point when cutting performance drops, or replace the bit if the diameter falls below .0890.
What limit appears first when drilling continuously with the #43 jobber bit?
Heat buildup at the 118° point softens the high speed steel, causing rapid edge dulling; use cutting fluid and peck drilling to manage temperature.
