Hertel 85703940 Jobber Drill Bit Size 17 Hss 0.1730 in

Product Description

The HERTEL 85703940 is a jobber length drill bit designed for general-purpose hole-making in metal, wood, and plastic. Built from high speed steel with a bright, uncoated finish, it cuts right-hand and features a standard 118-degree point angle that suits a wide range of common drilling applications. The straight-cylindrical shank seats securely in standard drill chucks. At 3-3/8 inches overall length with a 2-3/16 inch flute length, this is a compact, balanced bit sized for benchtop drill presses, hand drills, and production setups. The wire gauge size 17 corresponds to a decimal diameter of 0.1730 inches. It is sold individually and is a staple for maintenance techs, fabricators, and trade professionals who drill frequently in mixed materials.

This bit is suited for general production and maintenance drilling in residential and commercial environments. The 0.1730-inch diameter falls within the 0.1500 to 0.2000 inch drill bit size range, making it a mid-range wire gauge option. Typical applications include pilot holes, clearance holes, and general through-hole work in ferrous and non-ferrous metals as well as wood and thermoplastics. The tapered web and web-thinned geometry reduce thrust at the cutting face, helping maintain control during entry.

Installation Notes

Installation is performed by machinists, maintenance technicians, and trade professionals using standard 3-jaw or keyless drill chucks. Secure the shank fully in the chuck before operation and confirm the bit runs true before drilling. Always wear appropriate eye protection and secure the workpiece before applying feed pressure. For metal drilling, use a cutting fluid or lubricant to extend bit life and improve hole quality.
