General-purpose jobber drill bit
The Chicago-Latrobe 44008 is a 1/8-inch jobber length drill bit designed for general-purpose drilling in metal, wood and plastic. Its 118-degree conventional point angle suits a wide range of handheld and bench-top drilling tasks. The high-speed steel body with black oxide finish resists wear and reduces chip welding during use. This fractional-inch bit fits standard three-jaw chucks without adapters.
Straightforward chuck fit and common pitfalls
The 0.1250-inch decimal shank seats directly in any 1/8-inch or larger drill chuck, so no special collets or sleeves are required. The non-coolant-through design means chips must be cleared manually in deep holes. Overheating occurs quickly if feed pressure is too high or cutting fluid is omitted in steel. The conventional point can walk on hard surfaces unless a centre punch mark is used first.
Steady cutting under sustained load
The high-speed steel construction maintains hardness during extended drilling sessions better than carbon-steel alternatives. Black oxide coating helps retain lubricity when the bit runs warm, reducing galling in aluminium and mild steel. Without internal coolant holes, heat builds up in holes deeper than three diameters, so periodic withdrawal is necessary. The 118-degree point stays sharp longer in abrasive materials than sharper split-point designs.

Questions about this item
How can I confirm the 118-degree point is cutting cleanly after I start drilling?
A properly sharpened 118-degree conventional point will centre itself without wandering and produce continuous, straw-coloured chips in mild steel; if the bit walks or creates powdery dust, re-sharpen or replace it.
What comes in the package and what must I supply myself?
The box contains the single 44008 jobber-length bit made of high-speed steel with black-oxide finish; you must provide a drill chuck that accepts a 1/8-inch shank and any cutting fluid you prefer.
When should I choose the 44008 over other fractional sizes?
Select the 44008 when the drawing or tap chart calls for a 0.1250-inch (1/8-inch) hole; other fractional sizes in the same series have different decimal equivalents and will not match that specification.
