Westward #7 Jobber Drill Bit
The Westward #7 HSS black-oxide jobber drill bit is a high-speed steel twist bit with a 118-degree conventional point and a decimal size of .2010 inch. It is aimed at machinists, maintenance technicians and DIY users who need a general-purpose bit for drilling mild steel, cast iron and similar ferrous metals.
Replacing dull or undersized bits
A fresh #7 bit restores clean hole size when an older bit has worn below .2010 inch or when a smaller pilot hole must be opened to the exact wire-gauge diameter. The upgrade is worth it when hole tolerance matters for tapping, reaming or fastener fit and the current tool shows wandering, chatter or oversize entry.
Limits of the 118-degree point
The standard 118-degree point works well in rigid setups with flood or mist coolant but can walk on curved surfaces or in handheld drilling without a centre punch. Black-oxide finish aids chip flow in steel yet offers less heat resistance than coated alternatives, so sustained high-speed runs in tough alloys may reduce edge life. Prop 65 warnings apply.

Questions about this item
What drill chuck size is needed for the 0.2010 inch diameter shank?
Use a standard drill chuck that accepts a 0.2010 inch straight shank; the jobber length bit fits common three-jaw chucks without a special adapter.
How do I start the hole correctly with the 118 degree conventional point?
Center-punch the workpiece, apply steady pressure, and let the 118 degree point self-centre without wandering; do not force the bit or use excessive speed.
When should the black oxide coating be considered worn and the bit replaced?
Replace the bit when the black oxide finish has worn off the cutting lips, the 118 degree point shows visible rounding, or the 0.2010 inch diameter no longer cuts cleanly.
