Hertel 84580919 Jobber Drill Bit No 17 0.1730 in Hss

Product Description

The HERTEL 84580919 is a No. 17 wire-size jobber-length drill bit designed for general-purpose holemaking in metal, wood, and composite materials. It is manufactured from high speed steel with an oxide coating that provides lubricity and mild corrosion resistance during drilling operations. The 135-degree split point reduces walking on contact and requires less feed pressure than a conventional 118-degree point. The bit features a right-hand spiral flute with a regular helix, a straight cylindrical shank sized at 0.1730 inches in diameter, and is graded for heavy-duty use. It is sold individually but requires a minimum order quantity of 12 units per purchase.

This drill bit is suited for production and maintenance applications where consistent hole quality in metal is required. The No. 17 wire size at 0.1730 inches is commonly used to produce clearance holes for No. 10 machine screws and similar fastener prep work. It is appropriate for use in drill presses, CNC machining centers, and hand-held electric drills. Machinists, maintenance technicians, pipefitters, and sheet metal workers routinely use jobber-length bits of this specification for repetitive drilling tasks in shop and field environments.

Key Features

• 135-degree split point reduces bit walking and decreases required feed pressure at entry
• Web-thinned, tapered web configuration improves chip clearance and cutting efficiency
• Oxide coating adds surface lubricity and provides mild protection against corrosion
• High speed steel construction withstands heat generated during high-cycle metal drilling
• Right-hand cut with regular spiral flute for standard clockwise drill operation
• Straight cylindrical shank fits standard three-jaw drill chucks without adapters

Compatibility

Designed as a standard jobber-length drill bit compatible with any three-jaw chuck or collet system accepting a 0.1730-inch straight cylindrical shank. Conforms to NAS specification designation for this bit series.

Installation Notes

Install the shank fully and evenly into the drill chuck and tighten securely before operating. Ensure the workpiece is clamped or fixtured to prevent rotation during drilling. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and improve hole finish. Inspect the cutting edges for wear or chipping before each use and replace the bit when point geometry is compromised.
