Hertel 71206643 Jobber Drill Bit Wire 47 Hss Oxide

Product Description

The HERTEL 71206643 is a jobber-length twist drill bit sized to wire gauge 47, equivalent to 0.0785 inches in diameter. Manufactured from high speed steel with an oxide coating, this bit delivers reliable performance in general-purpose drilling applications. The standard 118-degree split point and right-hand spiral flute are designed to produce clean entry holes in ferrous and non-ferrous materials. With a 2-inch overall length and straight cylindrical shank, it seats securely in standard drill chucks without the need for adapters. Licensed machinists, maintenance technicians, and skilled tradespeople reach for this size when working with small-diameter through-holes in sheet metal, mechanical assemblies, and fabrication work.

This bit is well suited for light- to medium-duty production and maintenance drilling in shop and field environments. Its 1-inch flute length accommodates typical depth requirements for wire-gauge-sized holes in metal panels, brackets, and structural components. The regular spiral and tapered web configuration help evacuate chips efficiently during drilling, reducing the need for frequent bit withdrawal in through-hole operations. It is sold individually and is commonly purchased in multiples for tooling kits.

Key Features

• Wire gauge 47 size — 0.0785 inches diameter for precise small-bore drilling
• 118-degree standard drill point for general-purpose entry into ferrous and non-ferrous stock
• High speed steel construction with oxide coating for wear and corrosion resistance
• Right-hand cut with regular spiral flute for efficient chip evacuation
• Web-thinned, tapered web configuration reduces thrust and improves cutting efficiency
• Straight cylindrical shank fits standard drill chucks and collet holders

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with standard three-jaw drill chucks and collet systems accepting a 0.0785-inch straight cylindrical shank.

Installation Notes

This bit should be installed by a qualified machinist or technician familiar with proper drill press, hand drill, or CNC setup procedures. Secure the shank fully in the chuck and verify runout before drilling. Use appropriate cutting fluid when drilling hardened or thick ferrous materials to extend bit life. Always wear appropriate eye protection and ensure the workpiece is properly fixtured before operation.
