Chicago-Latrobe 44408 1/8 in drill bit
The Chicago-Latrobe 44408 is a jobber length drill bit made from high speed steel. It features a 118 degree point angle and a left-hand helix design. The bright uncoated finish suits general purpose drilling tasks.
Suited for left-hand drilling operations
This bit suits mechanics and machinists who need to remove broken fasteners or operate in reverse. The left-hand helix prevents the bit from tightening a stuck screw. Buyers who need a standard right-hand cutting action should look at something else.
118 degree conventional point angle
The 118 degree conventional point angle determines how the bit starts and cuts in various materials. It centres well without a pilot hole in mild steel and wood. A different point angle would change the drilling behaviour entirely.

Questions about this item
How do I install the 1/8 in jobber drill in my drill chuck and what step is often missed?
Insert the 0.1250 in shank fully into the chuck jaws and tighten securely; the step often missed is verifying the bit runs true before starting the hole.
What maintenance or replacement will the high-speed steel 118° left-hand helix drill need later?
The bright uncoated HSS cutting edges will dull with use; plan to resharpen the conventional point to the original 118° angle or replace the bit when it no longer cuts cleanly.
What limit appears first during sustained drilling with this non-coolant-through jobber bit?
Heat builds quickly in the flute because there are no coolant holes; the bit loses hardness first, so reduce feed pressure or pause to let it cool.
