Hertel 84581099 Jobber Drill Bit No 35 Hss Oxide

Product Description

The HERTEL 84581099 is a No. 35 wire-size jobber-length drill bit designed for general-purpose holemaking in metal and other materials. Built from high speed steel with an oxide coating, this bit delivers reliable performance in production and maintenance drilling applications. The 135-degree split point reduces walking on contact and requires less thrust than a standard 118-degree point. The web-thinned, tapered web construction improves chip evacuation and reduces heat buildup at the cutting edge. This bit is suited for use by machinists, maintenance technicians, and trade professionals working with hand drills, drill presses, and CNC equipment.

The 84581099 is a heavy-duty grade jobber drill intended for repetitive holemaking tasks in shop and field environments. Its straight-cylindrical shank seats securely in standard three-jaw chucks. The regular spiral flute geometry and right-hand cutting direction make it compatible with conventional drill presses and handheld power tools. It is commonly used in HVAC, plumbing, electrical, and mechanical trades for drilling pilot holes, conduit knockouts, and fastener clearance holes in ferrous and non-ferrous stock.

Key Features

• No. 35 wire size (0.1100 inches decimal) for precise small-diameter drilling
• 135-degree split point reduces bit walking and lowers required thrust
• High speed steel construction with oxide coating for corrosion resistance and lubricity
• Web-thinned tapered web improves chip flow and reduces heat at the cutting zone
• Straight-cylindrical shank fits standard drill chucks without modification
• Heavy-duty grade jobber series meets NAS specification requirements

Compatibility

Designed as a standard jobber-length replacement drill bit for use in any three-jaw chuck or collet system accepting a 0.1100-inch straight-cylindrical shank.

Installation Notes

Install in a properly rated drill press, hand drill, or CNC spindle with a chuck or collet matched to the 0.1100-inch shank diameter. Ensure the workpiece is securely clamped before drilling. Use appropriate cutting fluid for ferrous materials to extend bit life and maintain dimensional accuracy. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
