Hertel 85703908 Jobber Drill Bit Wire 13 Hss 118 Degree

Product Description

The HERTEL 85703908 is a jobber-length drill bit in wire gauge size 13, with a decimal diameter of 0.1850 inches. It is manufactured from high speed steel with a bright, uncoated finish and a standard 118-degree split point. The 2-flute spiral flute design with a tapered web and web-thinned point supports efficient chip evacuation and clean entry in a wide range of materials. At 3.5 inches overall length with a 2.3125-inch flute length, this bit fits standard drill chucks via its straight-cylindrical shank. It is suited for general-purpose drilling applications performed by machinists, maintenance technicians, and skilled tradespeople.

This bit is designed for general-purpose drilling in metals, plastics, and wood composites. The 0.1850-inch diameter falls within the 0.1500 to 0.2000 inch size range for jobber-length tooling. The right-hand cutting direction and regular spiral type make it compatible with standard drill presses, hand drills, and CNC drilling setups where a straight-shank jobber bit is required. No coolant-through capability is present, so external coolant or cutting fluid should be applied manually when drilling harder ferrous metals.

Key Features

• Wire gauge size 13 with 0.1850-inch decimal diameter
• High speed steel construction for general-purpose drilling in metal, plastic, and wood
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust and easier starting
• 2-flute regular spiral design promotes efficient chip removal
• Bright uncoated finish — compatible with cutting fluids for extended tool life
• Straight-cylindrical shank fits standard 3-jaw drill chucks

Compatibility

Designed as a general-purpose jobber-length drill bit suitable for use in standard drill presses, portable hand drills, and CNC drilling equipment accepting a straight-cylindrical shank in the 0.1850-inch diameter range.

Installation Notes

Installation is performed by machinists and general maintenance technicians. Secure the straight shank firmly in the drill chuck before operation and verify runout before drilling precision holes. When drilling ferrous metals, apply a cutting fluid manually to the work surface to manage heat and extend bit life. Inspect the point and cutting edges for wear or chipping before each use, and replace the bit if the web-thinned point shows visible damage.
