Hertel 61698817 Screw Machine Drill Bit 21/32 Inch Hss

Product Description

The HERTEL 61698817 is a screw machine length drill bit designed for high-speed steel cutting in metal fabrication, machining, and industrial drilling applications. Built from high-speed steel with an oxide coating, this bit measures 21/32 inches (0.6562 inches) in diameter with a 118-degree standard point angle and a 4-1/2 inch overall length. The shorter screw machine length body improves rigidity and reduces deflection compared to jobber-length bits, making it well suited for production drilling on drill presses, lathes, and CNC equipment. Installation and use are handled by machinists and trade professionals working in general-purpose metal drilling applications.

This bit is appropriate for general-purpose drilling in ferrous and non-ferrous metals. The 2-7/8 inch flute length provides adequate chip clearance for the diameter class. The right-hand spiral flutes and standard 118-degree point geometry make it compatible with conventional drilling setups without requiring specialized tooling or point preparation. The straight cylindrical shank fits standard drill chucks across a wide range of machine platforms.

Key Features

• 21/32 inch diameter (0.6562 inches) for precise fractional sizing
• High-speed steel construction with oxide coating for wear resistance
• 118-degree standard point angle for general-purpose metal drilling
• Screw machine length body reduces deflection and improves rigidity
• Right-hand cut with 2-flute regular spiral for efficient chip evacuation
• Straight cylindrical shank fits standard drill chucks

Compatibility

Designed as a general-purpose screw machine length drill bit conforming to ANSI specifications, compatible with standard drill chucks accepting a straight cylindrical shank in the 21/32 inch diameter range.

Installation Notes

This bit is installed and operated by machinists and trained drilling professionals. Secure the shank fully in a properly rated drill chuck before use and verify chuck runout is within acceptable limits for the diameter. Always power down and de-energize the machine before changing bits. Follow applicable shop safety standards and manufacturer recommendations for cutting speed and feed rate based on workpiece material.
