Hertel 16692220 Solid Carbide Drill Bit 19/64 Inch

Product Description

The HERTEL 16692220 is a solid carbide jobber length drill bit designed for precision drilling in ferrous and non-ferrous metals, plastics, and composite materials. It measures 19/64 inches (0.2969 inches decimal) in diameter with an overall length of 3-3/4 inches and a flute length of 2-3/8 inches. The bit features a titanium nitride (TiN) coating that increases surface hardness and extends tool life in high-cycle production environments. A 118-degree standard point angle suits general-purpose drilling applications. Machinists, tool-and-die workers, and maintenance technicians working with CNC equipment or manual drill presses are the primary users of this tool.

This bit is suited for shop floor, production line, and maintenance applications where consistent hole quality and dimensional accuracy are required. The right-hand spiral flute design promotes efficient chip evacuation. The straight-cylindrical shank is compatible with standard drill chucks and collet holders. Web thinning reduces thrust requirements at the point, making it practical for hand-held and machine drilling alike. It belongs to the HERTEL Series 450 and is sold individually.

Key Features

• Solid carbide construction with C2 material grade for rigidity and wear resistance
• TiN coating increases surface hardness and reduces friction during cutting
• 118-degree standard point angle with web-thinned, tapered web configuration
• Right-hand cut with regular spiral flute for positive chip ejection
• 19/64 inch diameter with a tight tolerance of -0.0005 to 0.0000 inches
• No coolant-through design; compatible with external coolant or dry cutting setups

Compatibility

Designed as an OEM-style replacement and production-grade jobber drill for use in standard drill chucks and collet systems accepting a 19/64 inch straight-cylindrical shank. Fits within the 0.2500 to 0.3000 inch decimal drill bit size range.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotary cutting tools. Ensure the drill press, lathe, or CNC spindle is fully powered down and locked out before loading or changing bits. Secure the straight-cylindrical shank firmly in a properly sized chuck or collet to prevent runout. Always operate within the recommended speed and feed parameters for solid carbide tooling to avoid bit fracture.
