Chicago-Latrobe 44036 118 Degree Jobber Length Drill Bit 9/16 in

Chicago-Latrobe 44036 Jobber Drill Bit

The Chicago-Latrobe 44036 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 9/16 inch fractional diameter with a decimal equivalent of .5625. The bit is non coolant through with zero coolant holes. It is designed for standard drilling applications in a workshop environment.

Suitable for general purpose drilling tasks

This bit suits users needing a standard high speed steel drill for common materials where a conventional point is adequate. It is not for buyers who require coolant through capability for deep hole drilling or chip evacuation. It is also not for operators needing specialised point geometries such as split points for reduced walking or specific angles for hard alloys. The lack of coating beyond black oxide limits wear resistance in high volume production.

9/16 inch diameter with 118 degree point

The .5625 inch diameter provides a standard fractional size for common fastener clearance or tapping operations. The jobber length offers typical flute length and overall reach for general bench work. Headroom runs out when drilling depths exceed the flute capacity for chip removal without coolant through assistance. The 118 degree point handles general materials but runs out of performance in very hard steels or abrasive composites where specialised geometry or premium substrates are required.
