Hertel 85707354 Jobber Drill Bit Wire 13 0.185in Hss Tin

Product Description

The HERTEL 85707354 is a jobber-length twist drill bit designed for general-purpose hole-making in metal, wood, and plastic. Built from high speed steel (HSS) with a titanium nitride (TiN) coating, it delivers extended wear resistance and reduced friction compared to uncoated HSS tooling. The bit measures 3.5 inches overall length with a 2-5/16-inch flute length and a straight-cylindrical shank diameter of 0.1850 inches, matching wire gauge size 13. The 118-degree standard point angle and regular spiral flute geometry suit a wide range of general machining, maintenance, and fabrication applications. Machinists, maintenance technicians, and tradespeople install this bit using standard drill presses, cordless drills, and hand-held power drills.

This bit is suited for production drilling and maintenance work in light manufacturing, HVAC fabrication, electrical rough-in, and general mechanical service. The wire size 13 designation and 0.1850-inch decimal diameter make it a common choice when drilling clearance holes for fasteners in sheet metal and structural steel. The 2-flute spiral design promotes chip evacuation during through-hole drilling in ferrous and non-ferrous materials. It is sold as a single unit, making it a practical replacement or addition to an existing drill index.

Key Features

• High speed steel construction with TiN coating for improved wear resistance and tool life
• Wire size 13 — 0.1850-inch decimal diameter with straight-cylindrical shank
• 118-degree standard point angle for general-purpose drilling across common materials
• Regular spiral flute with web-thinned, tapered web configuration for easier penetration and chip clearance
• 3.5-inch overall length with 2-5/16-inch flute length — standard jobber proportions
• Right-hand cut, 2-flute design compatible with conventional drill presses and handheld drivers

Compatibility

Designed as a general-purpose jobber-length drill bit fitting any standard drill chuck that accepts a 0.1850-inch straight-cylindrical shank.

Installation Notes

Secure the shank fully in the chuck and verify runout before drilling production holes. Always wear appropriate eye protection and secure the workpiece before starting the drill. For extended tool life, use cutting fluid when drilling ferrous metals. Replace the bit at the first sign of chatter, oversized holes, or excessive heat discoloration on the cutting edges.
