Hertel 71206379 Jobber Drill Bit Wire Size 20 Hss

Product Description

The HERTEL 71206379 is a jobber-length drill bit in wire gauge size 20, with a decimal diameter of 0.1610 inches. Made from high speed steel with an oxide coating, it is built for general-purpose drilling in metal, wood, and plastic. The bit features a 118-degree standard point angle, a 2-flute regular spiral flute design, and a web-thinned tapered web for improved chip evacuation and easier starting. Overall length is 3.25 inches with a 2.125-inch flute length. The straight-cylindrical shank seats in standard drill chucks. This bit is used by machinists, pipefitters, electricians, and general trade technicians for everyday hole-making tasks.

This bit is suited for light to medium-duty drilling applications in shop and field settings. Its wire gauge sizing makes it a go-to for tapping clearance holes, precision layouts, and any work requiring tight diameter tolerances in the 0.1500 to 0.2000-inch range. The oxide finish provides a degree of lubricity and corrosion resistance during operation. Right-hand cut orientation is standard for conventional drill press and hand-drill use. Sold individually, with a minimum order quantity of 12 units per order.

Installation Notes

Install and remove drill bits only with the drill unpowered and the chuck fully stopped. Use appropriate work-holding to secure the workpiece before drilling. Match spindle speed to material type per standard machining reference tables. Inspect the cutting edges for wear or chipping before each use and replace bits that show damage to avoid workpiece defects or bit breakage.
