15.5 mm Jobber Drill Bit
The Chicago-Latrobe 47368 is a general-purpose jobber length drill bit manufactured from high-speed steel with a black oxide finish. It features a conventional 118 degree point angle and a non-coolant-through design. This accessory is suited for standard drilling tasks in a workshop environment.
Best for standard metal drilling.
This bit suits users drilling common materials where a conventional point performs well. It lacks coolant holes, so it is not intended for machines requiring through-tool coolant delivery. Buyers needing internal coolant channels or specialised point geometries for exotic alloys should look elsewhere.
118 degree conventional point angle
The 118 degree point determines how the bit engages the workpiece and manages chip formation in general-purpose applications. It is the primary specification that defines suitability for standard drilling versus specialised high-performance or deep-hole requirements.

Questions about this item
How much heat does the 15.5 mm high-speed-steel bit generate during prolonged drilling?
The 118-degree conventional point and black-oxide finish are designed to dissipate heat efficiently while the high-speed-steel body resists softening during extended use.
What shank size must my drill chuck accept for the 15.5 mm jobber bit to fit?
The bit uses a standard straight shank matching its 15.5 mm diameter, so a chuck capacity of at least 15.5 mm or 0.6102 inch is required.
Will the 118-degree point on this 15.5 mm bit start cleanly in the softer metals I usually drill with older cobalt bits?
Yes, the 118-degree conventional point is intended for general-purpose drilling and centres reliably in mild steel, aluminium and other softer alloys without walking.
