Hertel 83245985 Carbide Jobber Drill Bit No. 80

Product Description

The HERTEL 83245985 is a solid carbide jobber-length drill bit sized to wire gauge No. 80, with a decimal diameter of 0.0135 inches. It features a standard 118-degree split point with web thinning for improved centering and reduced thrust on entry. The bright, uncoated finish is suited for general-purpose drilling where coating is not required. With an overall length of 0.75 inches and a flute length of 0.1875 inches, this is a precision micro drill designed for machinists, toolmakers, and production shops working with small-diameter bores in non-ferrous and soft materials.

This drill bit is rated for primary use in aluminum and non-ferrous materials. Its straight cylindrical shank and right-hand spiral flute make it compatible with standard collet chucks, drill chucks, and CNC spindle tooling. Typical applications include instrument manufacturing, electronics assembly, and precision machining where tight-diameter tolerances and consistent chip evacuation are required in very small hole work.

Key Features

• Solid carbide construction rated Material Grade C2 for general-purpose machining
• Wire gauge No. 80 diameter at 0.0135 inches with a tolerance of -0.0005 to 0.0000 inches
• 118-degree standard point angle with web thinning for accurate entry and reduced thrust
• Bright/uncoated finish for direct use in aluminum and non-ferrous workpiece materials
• Right-hand cut with regular spiral flute geometry for controlled chip removal
• Straight cylindrical shank at 0.0135 inches for compatibility with standard micro drill chucks

Compatibility

Designed as an OEM-style replacement or direct drop-in for No. 80 wire gauge drill applications requiring a solid carbide jobber-length bit with a straight shank and 118-degree point.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Secure the shank fully within the collet or chuck to the recommended grip depth before operation. Power down and lock out the spindle before changing or inspecting tooling. Micro-diameter carbide drills are brittle and should not be used in hand-held drill applications; use only in rigid machine setups to prevent breakage.
