Hertel 79892311 Carbide Jobber Drill Bit No.13

Product Description

The HERTEL 79892311 is a solid carbide jobber-length drill bit sized to wire gauge No. 13 (0.1850 inches diameter) with a 118-degree standard point angle. Built from C2-grade carbide with a bright finish, it delivers consistent hole geometry in ferrous and non-ferrous materials where high-performance tooling is required. The web-thinned, tapered web design reduces thrust force at entry and improves chip evacuation. With an overall length of 2.75 inches and a 1.625-inch spiral flute, this bit suits precision drilling operations in production, maintenance, and fabrication environments. It is installed by machinists, toolroom technicians, and skilled tradespeople using standard drill presses, CNC machining centers, or hand-held power tools.

This bit is intended for applications requiring tight diameter tolerances in the 0.1500 to 0.2000 inch size range. The straight-cylindrical shank fits standard collets and drill chucks without modification. Right-hand cutting direction and regular spiral flute geometry make it suitable for through-hole and blind-hole work in metals, plastics, and composite materials where a solid carbide substrate outperforms high-speed steel alternatives.

Key Features

• Solid carbide C2-grade substrate for extended tool life in abrasive and hard materials
• No. 13 wire gauge size at 0.1850 inches decimal equivalent
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• Bright finish coating with 2-flute regular spiral for efficient chip clearing
• Straight-cylindrical shank at 0.1850 inches diameter for universal chuck compatibility
• Diameter tolerance of -0.0005 to 0.0000 inches for consistent, precise hole sizing

Compatibility

Designed as a jobber-length replacement drill bit for applications requiring a No. 13 wire gauge (0.1850 inch) solid carbide bit with a straight-cylindrical shank and 118-degree point in standard drill chucks and collet systems.

Installation Notes

Installation and use should be performed by qualified machinists or tradespeople familiar with rotary cutting tools. Ensure the drill press, lathe, or CNC spindle is powered down and locked out before inserting or removing the bit from the chuck or collet. Secure the shank fully in the holding device to the manufacturer-specified grip depth to prevent pullout. Coolant-through is not supported on this bit; apply external cutting fluid as appropriate for the workpiece material.
