Chicago-Latrobe 7/16" HSS Jobber Drill Bit
This Chicago-Latrobe 44428 jobber drill bit has a 7/16 inch diameter and a 118 degree conventional point. It is made from High Speed Steel with a bright uncoated finish. The fractional inch size suits general purpose drilling tasks in a workshop.
Suitable for mechanics
The 0.4375 inch decimal equivalent fits standard drill chucks for handheld or press use. It lacks coolant holes so it is not for deep hole production or internal coolant systems. Buyers needing coated tips or specialised point geometry should look at other options.
118 degree conventional point angle
The 118 degree point angle is the critical specification that determines material suitability and cutting behaviour. This angle works well for mild steel, aluminium and wood. A different point angle would be required for hard alloys or specific high performance applications.
