Left-Hand Helix Jobber Drill Bit
This Chicago-Latrobe 44426 drill bit features a 13/32 in diameter with a 118 degree point angle. The left-hand helix design suits specific extraction tasks. High speed steel construction provides durability for general purpose drilling. It is a fractional inch jobber length tool.
Replaces standard right-hand bits for extractor use
Switch to this bit when a left-hand rotation is required to back out damaged fasteners. The conventional point starts cleanly in metal without a pilot hole. Bright uncoated finish preserves the factory geometry. The jump is worth it when standard bits cannot engage the broken stud.
Check drill chuck capacity and rotation direction
Verify your chuck accepts a 13/32 in shank before ordering. Confirm the power tool offers a reverse function for left-hand cutting. Ensure the workpiece material suits high speed steel without coolant. No coolant holes are present on this model.

Questions about this item
What chuck size is needed for the 13/32 in shank on this jobber drill?
A 13/32 in (0.4063 in) chuck capacity is required to hold the straight shank of this high-speed steel drill bit.
How should the left-hand helix bit be started to avoid wandering on the first hole?
Use a centre punch mark and light feed pressure; the 118-degree conventional point cuts on the left-hand spiral so reverse spindle rotation is essential.
When does the bright uncoated 118-degree point need resharpening or replacement?
Resharpen when the cutting lips show visible wear or the drill produces discoloured chips; the uncoated HSS can be reground multiple times before replacement.
