Hertel 84581206 Jobber Drill Bit No 46 Hss 135 Deg

Product Description

The HERTEL 84581206 is a No. 46 wire-gauge jobber-length drill bit engineered for precision holemaking in metal and similar materials. Built from high speed steel with an oxide coating, this bit runs a 135-degree split point that reduces walking on entry and lowers the thrust required to start a hole. At 0.0810 inches in diameter and 2.125 inches overall length, it fits applications where tight tolerances and small-bore accuracy matter. The two-flute spiral design clears chips efficiently during drilling. A web-thinned, tapered web configuration further reduces cutting resistance. This bit is a standard tool for machinists, maintenance technicians, and trade professionals who work with small-diameter holes in production or field settings.

This drill bit is suited for holemaking tasks in light to heavy-duty trade and manufacturing environments. Its straight-cylindrical shank seats directly in standard drill chucks without adapters, making it practical for handheld drills, drill presses, and CNC setups. The NAS specification designation indicates it meets established dimensional and performance standards for jobber-series drill bits. It is a common choice when consistent hole quality at the No. 46 wire size is required across repeat operations.

Key Features

• No. 46 wire size, 0.0810-inch diameter for precise small-bore drilling
• 135-degree split point reduces walking and lowers entry thrust
• High speed steel construction with oxide coating for heat and wear resistance
• Web-thinned, tapered web reduces cutting resistance through the material
• Two-flute regular spiral design promotes efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a standard jobber-series replacement or working drill bit for any drill chuck accepting a 0.0810-inch straight-cylindrical shank, covering the 0.0500 to 0.1000 inch drill bit size range per NAS specification.

Installation Notes

Install and remove drill bits only when the drill or drill press is fully powered down and the chuck is stationary. Secure the straight-cylindrical shank firmly in the chuck to the full depth of the chuck jaws to prevent runout. Use appropriate cutting fluid or coolant for the material being drilled where recommended by shop practice. Inspect the split point for wear or chipping before each use, as a damaged point will reduce hole accuracy and increase tool deflection.
