Chicago-Latrobe 44430 Left-Hand Jobber Drill
This Chicago-Latrobe 44430 drill bit is a jobber-length tool designed for creating holes in metal and other materials. Its left-hand helix direction allows it to operate in reverse rotation, which is useful for extracting broken fasteners or working with specific machinery setups. The bright, uncoated high-speed steel construction provides a standard cutting surface for general-purpose drilling tasks.
118-Degree Conventional Point Limits
The 118-degree conventional point angle is suited for general drilling across a range of materials but requires proper centring to prevent walking on hard or smooth surfaces. As a non-coolant-through bit with zero coolant holes, it relies on external lubrication or peck drilling cycles to manage heat and evacuate chips effectively during deeper cuts. The jobber length offers standard reach and rigidity for typical workshop applications.
15/32 Inch Diameter Fit
The critical specification is the 15/32 inch diameter, which corresponds to a decimal equivalent of .4688 inches. This exact fractional size determines compatibility with specific tap drill charts, clearance hole requirements, or fastener specifications. Buyers needing a different diameter, a coated surface for extended wear, or a split-point geometry for self-centring must select an alternative bit.

Questions about this item
Should I choose the 15/32 in size or look for another diameter?
The 15/32 in diameter equals .4688 in decimal, matching the exact fractional size listed for this jobber bit.
What does the 118 degree point angle do when I am drilling?
The 118° conventional point centres quickly in steel and general-purpose materials without needing a pilot hole.
How does the left-hand helix affect the way the bit cuts?
The left-hand helix pulls chips outward in reverse rotation, which helps extract broken studs or bolts.
