Hertel C.40W.0476 Taper Length Drill Bit Hss 0.1875 in

Product Description

The HERTEL C.40W.0476 is a taper length twist drill bit designed for precision drilling in metal, fabrication, and general machining applications. Built from high-speed steel (HSS) with a black oxide finish, this bit offers corrosion resistance and reduced friction during cutting. The 118-degree standard point angle suits a wide range of common drilling tasks. The web-thinned, tapered web design reduces thrust requirements at the cutting tip, making it easier to start and maintain accurate holes. It weighs 0.4 pounds and measures 5.75 inches in overall length with a 3.375-inch flute length. A licensed machinist, tool-and-die professional, or skilled maintenance technician will find this a reliable, production-grade drill for everyday hole-making operations.

This drill bit is suited for ferrous and non-ferrous metals, plastics, and general-purpose shop materials where a taper length drill provides deeper reach than a jobber-length bit without requiring extensions. The straight cylindrical shank at 0.1875 inches diameter fits standard drill chucks on bench drill presses, magnetic drills, and hand drills. Right-hand spiral flutes clear chips efficiently during through-hole and blind-hole drilling. The regular spiral and tapered web configuration support consistent cutting performance across repetitive production runs or one-off repair work.

Key Features

• HSS construction provides hardness and heat resistance suitable for metal drilling
• Black oxide coating reduces friction and provides light corrosion protection
• 118-degree standard point angle for general-purpose drilling across common materials
• Web-thinned tapered web reduces drilling thrust and improves hole-starting accuracy
• Taper length body offers greater reach than standard jobber bits without extensions
• Right-hand spiral flutes promote efficient chip evacuation from the cut zone

Compatibility

Designed as a direct-fit taper length drill bit for use in any standard drill chuck accepting a 0.1875-inch straight cylindrical shank, including bench drill presses, magnetic drills, and hand-held electric drills.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician familiar with drill press or hand-drill operation. Ensure the drill chuck is fully tightened and the workpiece is secured before beginning operation. Use appropriate cutting fluid when drilling hard metals to extend tool life and maintain hole quality. Inspect the cutting edges for wear or chipping before each use and replace the bit if damage is observed.
