Hertel 61698650 Screw Machine Drill Bit 19/32 in Hss

Product Description

The HERTEL 61698650 is a screw machine length drill bit designed for general-purpose drilling in metal fabrication, machining, and maintenance applications. Built from high-speed steel with an oxide coating, this bit measures 19/32 inches (0.5938 inches decimal) in diameter and features a 118-degree standard point angle optimized for starting and penetrating common ferrous and non-ferrous materials. The shorter screw machine length body reduces deflection in close-clearance setups such as drill presses, CNC turret machines, and hand-held drilling applications where a stub-length bit is preferred. Right-hand cutting direction and a straight-cylindrical shank provide straightforward chuck compatibility across standard equipment.

This bit is suited for production and job-shop environments where consistent hole quality in steel, cast iron, aluminum, and similar materials is required. The 3xD flute-to-diameter ratio and 2-flute spiral design promote chip evacuation in moderate-depth holes. Machinists, tool-and-die technicians, millwrights, and maintenance mechanics will find this a dependable general-purpose option when drilling within the 0.5000 to 0.6000 inch diameter range.

Key Features

• 19/32 inch (0.5938 inch decimal) diameter for precise hole sizing
• 118-degree standard point angle for broad material compatibility
• High-speed steel construction with oxide coating for wear resistance
• Screw machine (stub) length reduces deflection in tight setups
• 2-flute regular spiral design promotes efficient chip evacuation
• Right-hand cut, straight-cylindrical shank fits standard three-jaw chucks

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with standard drill presses, CNC turret machines, and hand-held drilling equipment accepting a straight-cylindrical shank in the 0.5000 to 0.6000 inch diameter range. Meets ANSI specification designation.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tools. Secure the shank fully in the chuck before operation and verify spindle speed is appropriate for the material and bit diameter. Always wear appropriate eye protection and ensure the workpiece is properly clamped or fixtured before drilling. Do not use a dull or damaged bit, as this increases heat buildup and breakage risk.
