Hertel 16691719 Jobber Drill Bit 1/8 in Solid Carbide Tin

Product Description

The HERTEL 16691719 is a jobber-length drill bit designed for precision drilling in hard and abrasive materials. Built from solid carbide grade C2 and finished with a Titanium Nitride (TiN) coating, this bit delivers extended tool life and reduced friction in demanding production and maintenance environments. It measures 1/8 inch in diameter with a 2-1/4 inch overall length and a 1-1/4 inch flute length. The standard 118-degree point angle and web-thinned, tapered web geometry promote clean entry and reduce thrust requirements. This bit is sold individually and is suited for machinists, fabricators, and maintenance technicians working with ferrous and non-ferrous metals.

This drill bit is appropriate for use in CNC machining centers, drill presses, and hand-held power drills where tight tolerances and clean bore quality are required. It is well suited for light-duty precision work in metal fabrication shops, tool rooms, and industrial maintenance settings. The straight-cylindrical shank accommodates standard drill chucks across a wide range of equipment. Coolant-through capability is not supported on this model.

Key Features

• Solid carbide C2 grade construction for hardness and wear resistance in abrasive materials
• Titanium Nitride (TiN) coating reduces friction and extends cutting life
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust and clean entry
• 2-flute regular spiral flute design promotes chip evacuation
• Right-hand cut with straight-cylindrical shank for broad chuck compatibility
• Diameter tolerance of -0.0005 to 0.0000 inches for consistent, close-tolerance bore sizing

Compatibility

Designed as a replacement-style jobber-length drill bit for use in standard drill chucks accepting a 1/8 inch straight-cylindrical shank, across CNC and manual drilling equipment in the 0.1000 to 0.1500 inch diameter range category.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician. Ensure the drill chuck is fully de-energized and the spindle is at a complete stop before inserting or removing the bit. Secure the shank fully within the chuck jaws and verify concentricity before beginning any operation. Carbide tooling is brittle and should not be subjected to side loading, impact, or excessive feed rates that exceed the bit's rated capacity.
