Hertel 85703395 Jobber Drill Bit 1/8 Inch Hss 118 Degree

Product Description

The HERTEL 85703395 is a jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastics. Ground from high speed steel with a bright uncoated finish, it runs a standard 118-degree point angle with web thinning applied for easier center starting and reduced thrust. The straight-cylindrical shank measures 1/8 inch in diameter, making it compatible with standard three-jaw chucks. Two spiral flutes with a regular helix evacuate chips efficiently during through-hole drilling. Overall length is 2.75 inches with a flute length of 1.625 inches. This bit is sold individually and is a staple in maintenance, fabrication, and trade service kits.

This bit is suited for light-duty drilling tasks in residential and commercial maintenance environments, HVAC and plumbing rough-in work, electrical trade drilling, and general fabrication. Its 1/8-inch diameter is commonly used for pilot holes, sheet metal penetrations, and small-diameter through holes. The right-hand cut and standard spiral type make it straightforward to run in any variable-speed drill or drill press at appropriate feed and speed rates for the workpiece material.

Key Features

• 118-degree standard point angle with web thinning for reduced entry thrust
• High speed steel construction for general-purpose durability across multiple materials
• Bright uncoated finish suitable for use with cutting fluid when needed
• Two-flute regular spiral design for consistent chip evacuation
• Straight-cylindrical shank fits standard three-jaw chucks without modification
• Tapered web configuration adds rigidity to the cutting zone

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard three-jaw chucks and drill presses accepting a 1/8-inch straight shank.

Installation Notes

This bit is installed and used by machinists, maintenance technicians, electricians, plumbers, and HVAC technicians. Secure the shank fully in the chuck before drilling and verify the workpiece is clamped or fixtured to prevent rotation. Use appropriate cutting speeds for the workpiece material and apply cutting fluid when drilling ferrous metals to extend bit life. Replace the bit when point geometry is visibly worn or when heat discoloration indicates the temper has been compromised.
