Hertel C.40W.0119 Taper Length Drill 3/64 Inch Hss

Product Description

The HERTEL C.40W.0119 is a taper length twist drill bit designed for precision drilling in metal, wood, and composite materials. It measures 0.0469 inches (3/64 inch) in diameter with an overall length of 2.25 inches and a flute length of 1.125 inches. The bit is manufactured from high-speed steel (HSS) with a black oxide finish that reduces friction and provides mild corrosion resistance during cutting operations. The 118-degree standard point angle suits general-purpose drilling applications. A web-thinned, tapered web configuration reduces thrust and improves chip evacuation. This drill bit is sold individually and is a standard consumable tool stocked and used by machinists, maintenance technicians, and trade professionals.

This drill bit is suited for small-diameter precision work in light-gauge metals, plastics, and similar materials. The straight-cylindrical shank fits standard drill chucks across benchtop drill presses, CNC machines, and hand-held drill motors. The right-hand spiral flute design provides consistent chip removal during through-hole and blind-hole drilling. The taper length body gives additional reach compared to a jobber-length bit of the same diameter, making it useful in applications where standard-length bits cannot access the work.

Key Features

• 3/64 inch (0.0469 inch) diameter for small-hole precision drilling
• HSS construction provides hardness and heat resistance for metal drilling
• Black oxide finish reduces friction and provides mild corrosion resistance
• 118-degree standard point angle for general-purpose use
• Web-thinned tapered web reduces thrust and improves chip clearance
• Right-hand cut with regular spiral flute for consistent chip evacuation

Compatibility

Designed as a general-purpose taper length drill bit compatible with any standard drill chuck or collet system accepting a straight-cylindrical shank at 3/64 inch diameter.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard drill chuck or collet rated for the shank diameter. Ensure the chuck is fully tightened and the workpiece is securely clamped before operation. Use appropriate cutting fluid or coolant for metal drilling to extend tool life. Inspect the cutting edges before each use and replace worn or chipped bits to maintain hole quality and prevent tool breakage.
