Hertel 61699369 Screw Machine Drill Bit Wire 23 Hss

Product Description

The HERTEL 61699369 is a screw machine length drill bit sized to wire gauge number 23, with a decimal diameter of 0.154 inches. It is manufactured from high-speed steel with an oxide coating for improved lubricity and surface hardness during drilling operations. The bit features a standard 118-degree split point, two spiral flutes, and a straight cylindrical shank. Overall length is 2-1/16 inches, making it shorter than jobber-length bits and well suited for use in tight clearances or screw machine and turret lathe setups. Right-hand cut direction. General-purpose grade per ANSI specification.

This bit is designed for general-purpose drilling in metal, wood, and plastic in applications where a shorter, stiffer bit length improves accuracy and reduces deflection. Typical use cases include production drilling on screw machines, CNC turret lathes, and drill presses where controlled hole depth and positional accuracy are priorities. The 3xD flute-to-diameter ratio and 1-inch flute length support efficient chip evacuation at standard feed and speed rates for the material being drilled. Sold individually per package.

Key Features

• Wire gauge size 23, decimal equivalent 0.154 inches
• 118-degree standard point angle for general-purpose drilling
• High-speed steel construction for durability across a range of workpiece materials
• Oxide coating reduces friction and aids chip flow
• Screw machine length overall at 2-1/16 inches for reduced deflection in close-clearance setups
• Straight cylindrical shank compatible with standard drill chucks and collet holders
• ANSI specification designation, right-hand cut, two spiral flutes

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with standard drill chucks and collet systems accepting a straight cylindrical shank at 0.154 inches diameter.

Installation Notes

Install in a properly sized drill chuck or collet holder, ensuring the shank is fully seated and the chuck is tightened securely before operation. Power down and lock out the machine before changing bits. Verify spindle speed is appropriate for the workpiece material and bit diameter to prevent premature wear or breakage. Cutting fluid or coolant is recommended for metal drilling applications where possible.
