Hertel C.40W.0714 Taper Length Drill 9/32 Hss

Product Description

The HERTEL C.40W.0714 is a taper length twist drill bit ground from high-speed steel (HSS) with a black oxide finish. It cuts a 9/32-inch (0.2812-inch) diameter hole and features a standard 118-degree split point with web thinning for reduced thrust and cleaner entry. The flute length measures 3-7/8 inches with an overall length of 6-1/4 inches, giving it more reach than a jobber-length bit without sacrificing rigidity. Machinists, maintenance technicians, and tool-and-die tradespeople use this bit for drilling through mild steel, cast iron, aluminum, wood, and plastics where standard jobber bits fall short in depth.

This bit is suited for general-purpose drilling in production and maintenance environments. The taper length configuration makes it a practical choice when a jobber bit cannot reach the full required depth in deep-hole applications such as structural drilling, fixture fabrication, or machinery repair. It fits any drill press, milling machine, or hand drill with a straight-shank chuck capable of accepting a 9/32-inch shank. Right-hand spiral flutes evacuate chips efficiently during through-hole drilling.

Key Features

• 9/32-inch (0.2812-inch) diameter with matching straight-cylindrical shank for positive chuck grip
• 118-degree standard point angle with web thinning for reduced entry thrust
• Tapered web configuration and regular spiral flutes for consistent chip evacuation
• Black oxide finish provides mild lubricity and corrosion resistance during use
• 6-1/4-inch overall length gives added reach versus standard jobber-length drills
• Right-hand cut for use with conventional drill press and hand-drill rotation

Compatibility

Designed as an OEM-style taper length drill for use in any straight-shank chuck rated to accept a 9/32-inch diameter shank on drill presses, milling machines, or portable hand drills.

Installation Notes

Install and remove this bit with the machine fully powered down and the chuck key secured before starting the spindle. Secure the workpiece with clamps or a vise - never hand-hold a workpiece being drilled on a press. Use appropriate cutting fluid on ferrous materials to extend bit life and reduce heat buildup. Dispose of metal chips and worn bits in accordance with local shop safety guidelines.
