Chicago-Latrobe 44008 118 Degree Jobber Length Drill Bit

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.
