Hertel 79891685 Jobber Drill Bit Wire 67 Solid Carbide

Product Description

The HERTEL 79891685 is a wire gauge size 67 jobber length drill bit machined from solid carbide with a bright finish coating. It measures 0.0320 inches in diameter and 1.125 inches overall, with a flute length of 0.375 inches. The 118-degree standard point angle and web-thinned, tapered web geometry reduce entry thrust and improve chip evacuation in small-diameter drilling applications. The regular spiral flute design promotes consistent chip flow. This bit is suited for machinists, tool and die professionals, and precision fabrication shops working in tight-tolerance applications where a high-performance carbide tool is required.

This drill bit is designed for small-diameter, high-precision drilling where dimensional accuracy is critical. The diameter tolerance of -0.0005 to 0.0000 inches makes it appropriate for close-tolerance hole production in harder workpiece materials where high-speed steel tooling would wear prematurely. The straight cylindrical shank seats directly into standard collets and chucks. It is sold individually and is a practical choice for production drilling or low-clearance fixture work where compact overall length is an advantage.

Key Features

• Wire gauge size 67 at 0.0320 inches diameter with tight tolerance of -0.0005 to 0.0000 inches
• Solid carbide construction rated Material Grade C2 for high-performance applications
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• Bright finish coating on a regular spiral, two-flute configuration
• Right-hand cut with straight-cylindrical shank for standard collet or chuck mounting
• Compact 1.125 inches overall length with 0.375 inches of flute length

Compatibility

Designed as an OEM-style replacement or production tooling option for standard jobber length drill bit applications requiring a wire gauge size 67 solid carbide bit with a straight cylindrical shank.

Installation Notes

Installation and use of this bit should be performed by a qualified machinist or tooling professional. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the straight cylindrical shank firmly in a properly sized collet or drill chuck to prevent runout, which is especially critical at this small diameter. Do not exceed the spindle speed or feed rate recommended for solid carbide tooling in the workpiece material being drilled.
