Hertel 71206973 Jobber Drill Bit Wire 80 Hss Oxide

Product Description

The HERTEL 71206973 is a wire gauge size 80 jobber length drill bit designed for precision drilling in metalworking, machining, and light fabrication applications. Built from high speed steel with an oxide coating, it delivers reliable performance in general-purpose drilling where tight tolerances and small-diameter holes are required. The bit measures 0.0135 inches in decimal diameter and features a 118-degree point angle with a standard point type, making it suitable for a wide range of common materials including mild steel, aluminum, and plastics. It is sold individually and intended for use with drill presses, CNC equipment, or handheld power tools capable of holding a straight-cylindrical shank at this diameter.

This drill bit is sized for fine-detail work where a wire gauge 80 hole is specified, commonly encountered in electronics assembly, instrument manufacturing, mold making, and precision machining shops. The 3/4-inch overall length and 1/8-inch flute length make it appropriate for shallow-hole applications in confined workpieces. The right-hand spiral flute geometry provides standard chip evacuation for general-purpose use. This bit is sold one piece per package with a minimum order quantity of 12 units, making it suitable for shop stocking where small-diameter bits are consumed frequently.

Key Features

• Wire gauge size 80 at 0.0135 inches decimal diameter for fine-tolerance drilling
• High speed steel construction with oxide coating for general-purpose durability
• 118-degree standard point angle with web-thinned, tapered web configuration
• Regular spiral, two-flute design with right-hand cutting direction
• Straight-cylindrical shank for compatibility with standard chucks and collets
• No coolant-through requirement — suitable for dry or light-lubricant drilling

Compatibility

Designed as a general-purpose jobber length drill bit for use in any drill press, CNC machining center, or handheld power tool equipped with a chuck or collet capable of gripping a 0.0135-inch straight-cylindrical shank.

Installation Notes

Installation and use of small-diameter wire gauge drill bits should be performed by machinists or trade professionals familiar with high-speed drilling equipment. Secure the straight-cylindrical shank fully in the chuck or collet before operation to prevent runout and bit breakage. At this diameter, excessive feed pressure is the primary cause of bit failure — use light, consistent feed rates. Always power down and lock out the machine before changing bits.
