Hertel 85704450 Jobber Drill Bit 11/64 in Hss Tin

Product Description

The HERTEL 85704450 is a jobber-length drill bit designed for general-purpose metal drilling applications. Built from high speed steel (HSS) with a titanium nitride (TiN) coating, it delivers improved surface hardness and extended tool life compared to uncoated HSS. The 118-degree standard point angle suits a wide range of common materials. At 3.25 inches overall length with a 2.125-inch spiral flute, this bit handles typical through-hole and blind-hole work across sheet metal, mild steel, aluminum, and similar substrates. The straight-cylindrical shank fits standard three-jaw drill chucks without modification. Installation is straightforward for machinists, maintenance technicians, and trade professionals working with handheld or bench-mounted drilling equipment.

This bit is sized at 11/64 inch (0.1719 inch decimal equivalent), placing it in the 0.1500 to 0.2000 inch drill size range. It is suited for light-duty hole-making tasks in residential, commercial, and light industrial settings. Common applications include pilot holes for fasteners, conduit knock-outs in thin-wall enclosures, and general fabrication work. The web-thinned, tapered web configuration reduces thrust requirements and improves chip evacuation during cutting. The regular spiral flute geometry supports consistent chip flow in most standard drilling setups.

Key Features

• High speed steel construction with TiN coating for extended wear resistance
• 118-degree standard point angle for general-purpose use across common materials
• Web-thinned tapered web reduces cutting thrust and improves chip clearance
• Right-hand cut, 2-flute regular spiral flute for reliable chip evacuation
• Straight-cylindrical shank compatible with standard three-jaw drill chucks
• No coolant-through requirement simplifies setup in field and shop environments

Compatibility

Designed as a general-purpose jobber-length drill bit suitable for use in standard handheld drills, drill presses, and CNC drill chucks accepting an 11/64-inch straight-cylindrical shank.

Installation Notes

This drill bit is installed by trade professionals and machinists using standard three-jaw chucks on handheld or stationary drilling equipment. Ensure the chuck is fully tightened and the workpiece is properly secured before beginning drilling. Use appropriate cutting fluid when drilling steel to reduce heat buildup and prolong bit life. Inspect the cutting edges for wear before each use and replace the bit if chipping or dulling is observed.
