Hertel 61699278 Screw Machine Drill Bit Wire 5 Hss 118

Product Description

The HERTEL 61699278 is a screw machine length drill bit designed for general-purpose drilling in metal, wood, and plastic. It carries a wire gauge size of 5, equal to 0.2055 inches in decimal, and features a 118-degree standard point angle for reliable entry and consistent hole geometry. The shortened screw machine length body improves rigidity and reduces deflection compared to jobber-length bits, making it well suited for work in drill presses, CNC machines, and hand-held power drills where stub length is preferred. The bit is manufactured from high-speed steel with an oxide finish and is sold individually.

This drill bit fits standard general-purpose drilling applications across metalworking, mechanical assembly, and light fabrication environments. The 2-3/8 inch overall length and straight cylindrical shank allow direct chuck mounting without adapters. The right-hand cut and regular spiral flute geometry suit common production and maintenance drilling tasks. It is appropriate for machinists, millwrights, maintenance technicians, and trade professionals working in shop or field conditions where a compact, rigid drill bit is needed.

Key Features

• Wire size 5 diameter — 0.2055 inches decimal equivalent
• 118-degree standard point angle for general-purpose entry
• Screw machine length body improves rigidity and reduces deflection
• High-speed steel construction with oxide coating for corrosion resistance
• Right-hand cut with regular spiral fluting for efficient chip evacuation
• Straight cylindrical shank fits standard three-jaw chucks directly

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with any standard drill press, CNC drilling station, or hand-held power drill equipped with a chuck accepting a straight cylindrical shank in the 0.2000 to 0.2500 inch size range.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard keyed or keyless chuck. Secure the straight cylindrical shank firmly before operation and confirm the workpiece is clamped or fixtured to prevent movement. Follow applicable shop safety procedures and ANSI B11 machine tool standards when operating drill presses or CNC equipment. Do not exceed the recommended feed and speed ratings for the work material.
