Westward 3/16" HSS Black Oxide 118 Deg Jobber Drill Bit

3/16" HSS Jobber Drill Bit

This Westward drill bit is built for general-purpose drilling in metal, wood and plastic. The 3/16 inch diameter suits maintenance, fabrication and automotive tasks where a standard fractional size is required. It is aimed at technicians and DIY users who need a reliable, replaceable cutting tool for everyday workshop jobs.

118-Degree Conventional Point

The 118-degree point angle is the traditional choice for handheld drilling across a wide range of materials. It centres easily without a pilot hole but generates more thrust than split-point designs, so feed pressure must be controlled. The black oxide finish adds lubricity and corrosion resistance, yet the tool has no coolant-through capability, limiting its use in deep-hole or high-speed production work.

0.1875-Inch Decimal Equivalent

The bit’s 0.1875 inch decimal size matches a standard 3/16 fractional drill, fitting common chucks and tap-drill charts without conversion. High-speed steel construction handles typical shop materials, but the jobber length offers only moderate flute reach for deeper holes. Users needing extended reach, carbide wear life or through-coolant delivery will need a different tool specification.
