General-purpose jobber drill bit
The Chicago-Latrobe 44013 is a fractional-inch twist bit sized at 13/64 in with a conventional 118-degree point. It is made from high-speed steel with a black oxide finish for general-purpose drilling in metal, wood and plastic. The jobber length suits standard drill chucks and everyday workshop tasks.
Black oxide finish and conventional point
The black oxide coating reduces friction and resists corrosion during repeated use. A conventional 118-degree point centres quickly without a split-point design, while the solid construction has no coolant holes for dry drilling. These attributes suit hand-held or bench-mounted drilling where flood coolant is not used.
13/64 inch fractional size
The decimal equivalent is 0.2031 in, fixing the hole diameter for tap-drill or clearance-hole requirements. Buyers needing a different fractional size, a metric diameter, a split-point geometry or a coolant-through shank must choose another bit. This item is restricted from sale in certain states.

Questions about this item
Will the 13/64 inch high-speed steel tip need resharpening after repeated drilling?
Yes, the conventional 118-degree point on this high-speed steel bit will dull with use and can be resharpened to restore cutting performance.
What stops me from drilling deeper than the jobber-length flutes allow?
The jobber-length flute design limits chip clearance, so drilling deeper than the flute length risks clogging and bit binding.
Does the black-oxide finish keep the bit cool enough for all-day drilling in steel?
The black-oxide coating reduces friction and helps dissipate heat, but sustained high-speed drilling in steel will still generate noticeable heat.
