Hertel 85703809 Jobber Drill Bit Wire 3 Hss 118 Degree

Product Description

The HERTEL 85703809 is a jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastics. Built from high-speed steel (HSS) with a bright uncoated finish, it is sized to wire gauge No. 3, which corresponds to a decimal diameter of 0.2130 inches. The 118-degree standard point angle and web-thinned tip reduce entry force and walking on flat surfaces. The right-hand spiral flute design evacuates chips efficiently during through-hole and blind-hole drilling. At 3.75 inches overall length with a 2.5-inch flute length, this bit fits standard drill chucks and drill press setups used daily in fabrication and maintenance work.

This bit is suited for light- to medium-duty drilling applications in residential and commercial maintenance, mechanical fabrication, HVAC installation, plumbing rough-in, and electrical work where a wire-gauge No. 3 hole diameter is required. The straight-cylindrical shank accepts standard 3-jaw chucks on both handheld drills and drill presses. The tapered web construction adds rigidity and reduces the tendency to flex under load, making it reliable for repeated production use. Licensed tradespeople and experienced DIYers working with metal or composite materials will find this a dependable everyday bit.
