Hertel 84580760 Jobber Drill Bit No 3 Hss Oxide

Product Description

The HERTEL 84580760 is a No. 3 wire-size jobber-length drill bit ground from high speed steel with an oxide coating. It carries a 135-degree split-point tip and a web-thinned, tapered web geometry that reduces the thrust needed to start a hole and keeps the point on center without a pilot. The bit runs a standard right-hand spiral flute with a 2.5-inch flute length and a total overall length of 3.75 inches. The straight-cylindrical shank diameter matches the decimal drill size at 0.2130 inches, making it compatible with standard drill chucks. Rated heavy duty grade and manufactured to NAS specification, this bit is suited for production and maintenance drilling in metals and general-purpose materials.

This bit is used in holemaking operations across a wide range of trade and industrial applications. Typical uses include drilling pilot holes for fasteners, conduit knockouts, sheet metal work, and general fabrication tasks. The jobber-length geometry balances rigidity and reach, making it appropriate for hand-held drills, drill presses, and light CNC setups. Electricians, pipefitters, ironworkers, and general maintenance technicians regularly reach for this wire-size range when working to NAS tolerance standards in production environments.

Key Features

• No. 3 wire size with 0.2130-inch decimal diameter for precise, repeatable hole sizing
• 135-degree split point reduces walking and lowers entry thrust on hard materials
• Web-thinned tapered web improves chip clearance and cutting efficiency
• High speed steel construction with oxide coating for wear and heat resistance
• Right-hand spiral flute with regular helix for efficient chip evacuation
• Manufactured to NAS specification for dimensional consistency

Compatibility

Designed as a standard jobber-length drill bit for use in any 3-jaw or keyed drill chuck that accepts a 0.2130-inch straight-cylindrical shank, including handheld drills, drill presses, and compatible machine tool spindles.

Installation Notes

Install and remove drill bits only with the drill or press fully powered off and the chuck key removed from the chuck before operation. Secure the workpiece before drilling to prevent spinning or movement. Use appropriate cutting fluid or coolant when drilling metals to extend tool life and maintain hole quality. Eye protection and appropriate PPE are required whenever operating drilling equipment.
