Hertel C.40W.1905 Taper Length Drill Bit 0.75in Hss

Product Description

The HERTEL C.40W.1905 is a taper length drill bit designed for heavy-duty drilling applications in metal and industrial materials. Built from high-speed steel (HSS) with a black oxide finish, it measures 0.75 inches (3/4 inch) in diameter with a 118-degree standard point angle. The taper length body provides additional flute length compared to a jobber-length bit, giving machinists and tooling technicians deeper reach without switching to a longer specialty drill. Web thinning reduces thrust at the point for cleaner entry, and the tapered web configuration adds rigidity through the flute. This bit is turned by a straight-cylindrical shank compatible with standard drill chucks.

This drill bit is suited for machine shop, fabrication, and maintenance environments where drilling into steel, cast iron, aluminum, and similar materials is routine. The taper length format is a common choice when jobber-length bits lack the reach for deeper hole applications in fixtures, frames, or structural components. Right-hand spiral flute geometry handles the majority of general-purpose drilling operations on vertical mills, drill presses, and hand-held industrial drills.

Key Features

• 0.75 inch diameter HSS construction for strength in ferrous and non-ferrous metals
• 118-degree standard point angle for general-purpose drilling
• Black oxide finish reduces friction and provides mild corrosion resistance
• Web-thinned point reduces drilling thrust and improves chip ejection
• Taper length flute (5.875 inches) extends reach beyond standard jobber-length bits
• Straight-cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a general-purpose taper length drill bit for use in standard drill presses, knee mills, CNC machining centers, and industrial hand drills equipped with a 3/4 inch or larger drill chuck.

Installation Notes

Installation and use should be performed by machinists or qualified tooling technicians familiar with rotating cutting tools. Secure the shank fully in the drill chuck and verify runout before drilling. Always wear appropriate eye protection and use proper work-holding to prevent part movement. Cutting speed and feed rate should be set according to the workpiece material and machine capability to avoid overheating the cutting edge.
