5/64 Jobber Drill Bit

The Chicago-Latrobe 44005 is a general-purpose jobber length drill bit sized at 5/64 inch. It is made from high-speed steel with a black oxide finish for corrosion resistance. The 118-degree conventional point suits standard drilling tasks in metal, wood and plastic. This fractional-inch bit targets maintenance technicians and workshop users needing a reliable small-diameter cutter.

Sustained drilling behaviour

High-speed steel construction maintains hardness during extended use, while the black oxide surface reduces friction and heat buildup. The 118-degree point angle distributes cutting forces evenly, helping the bit stay sharp longer under continuous load. Without coolant-through channels, operators should use external lubrication or peck drilling to manage temperature in deeper holes. Consistent feed pressure prevents work hardening at the cutting edges.

Installation and common issues

The straight shank fits standard three-jaw drill chucks and quick-change adapters without adapters. Its 0.0781 inch decimal equivalent matches common fractional drill charts for easy size verification. The most frequent problem is breakage caused by excessive feed force or misalignment in handheld drills. Using a centre punch mark and reducing pressure as the bit breaks through minimises snapping and ensures cleaner hole exits.

Questions about this item

Does the 118-degree point angle on the 5/64 bit generate noticeable heat during extended drilling?

The 118-degree conventional point is a general-purpose geometry; heat buildup depends on workpiece material, cutting speed and lubrication rather than the bit alone.

What shank type does the 44005 bit use so I know if it fits my drill chuck?

The jobber-length bit has a straight round shank sized to its 5/64 diameter, fitting any standard three-jaw chuck that accepts that capacity.

Will the black-oxide high-speed steel bit wear quickly when used alongside older cobalt bits in the same job?

Black-oxide HSS offers good wear resistance for general-purpose work; mixing it with cobalt bits is normal practice and each bit wears at its own rate.
