Chicago-Latrobe 48927 Screw Machine Drill Bit
The Chicago-Latrobe 48927 is a screw machine drill bit sized at 27/64 in with a decimal equivalent of .4219. It is designed for machinists and maintenance technicians who need a left-hand cutting tool for specific screw machine applications.
High Speed Steel Construction With Bright Finish
The bit is manufactured from High Speed Steel with a bright, uncoated surface and a conventional 118 degree point angle. The left-hand cutting direction and non-coolant-through design imply it is suited for manual or automated screw machines where reverse rotation is required to extract fasteners or prevent workpiece tightening.
27/64 Inch Left-Hand Cutting Specification
The defining specification is the 27/64 in diameter combined with a left-hand cutting direction. This makes the bit the correct choice only for operations requiring that specific size and reverse rotation; it is not for buyers who need a right-hand cutting bit or a different diameter.

Questions about this item
Does the 118-degree point angle limit the materials I can drill effectively?
The 118-degree conventional point is designed for general-purpose drilling in mild steel, cast iron and non-ferrous metals; it is not optimised for hard alloys or deep-hole work.
What shank diameter does the 27/64-inch drill bit require in a chuck?
The shank matches the 27/64-inch (0.4219 decimal) drill diameter, so a three-jaw chuck must open to at least that size to grip it securely.
How do I install a left-hand cutting drill bit without damaging the flutes?
Insert the bit fully into the chuck, tighten evenly on all three jaws, then run the spindle in reverse (counter-clockwise) at the recommended speed for the material.
