Chicago-Latrobe 44412 Jobber Drill Bit
This Chicago-Latrobe 44412 jobber drill bit is a high-speed steel cutting tool designed for general-purpose drilling tasks. It features a conventional 118-degree point angle suitable for a wide range of materials. The bright, uncoated finish provides a standard surface for everyday workshop use.
Suited for general metalwork.
This bit suits mechanics and fabricators drilling standard fractional holes in mild steel, aluminium, or plastic where a 3/16 inch diameter is required. It is not intended for buyers who need coolant-through capability for deep-hole evacuation or a coated surface for extended wear in abrasive alloys. Users requiring a split-point geometry for self-centering without a pilot hole should look at a different design.
3/16 inch fractional diameter defines fit
The decisive specification is the 3/16 inch fractional diameter with a decimal equivalent of .1875, which determines the exact hole size produced. The 118-degree point angle governs how the bit engages the workpiece across common materials. Match this diameter and point angle to your application requirements to confirm compatibility.

Questions about this item
How do I install the 3/16" jobber bit in my drill chuck, and what step is often missed?
Open the chuck fully, insert the shank until it seats against the jaws, then tighten securely; the step often missed is verifying the bit runs true before drilling.
When will the 118-degree high-speed steel tip need replacement?
Replace the bit when the cutting lips show visible rounding or chipping, or when drilling requires noticeably more pressure and produces discoloured chips.
What limit appears first during sustained drilling with the .1875-inch diameter?
Heat buildup at the tip is the first limit; without coolant holes the bit loses hardness quickly, so pause frequently to let it cool.
