Hertel 83245779 Solid Carbide Spade Drill Bit 1/16 Inch

Product Description

The HERTEL 83245779 is a solid carbide spade drill bit designed for precision drilling in hard steel and high-strength materials. It features a 118-degree point angle and a bright, uncoated finish that suits a wide range of general-purpose drilling applications. With an overall length of 1.5 inches and a flute length of 0.3125 inches, this is a compact bit built for tight-tolerance work. Right-hand cutting direction and a web thickness of 0.015 inches contribute to stable, accurate entry in demanding materials. Licensed machinists, toolmakers, and industrial maintenance technicians typically work with tooling in this class.

This drill bit is intended for use in hard steel and high-strength material applications where carbide's rigidity and wear resistance outperform high-speed steel alternatives. The 1/16-inch diameter makes it suitable for small-hole work in production machining, precision fabrication, and maintenance environments. The bright finish means no coating interference, which is preferred when working with materials sensitive to coating chemistry or when re-grinding is expected. It is sold and packaged as a single unit.

Key Features

• Solid carbide construction for superior hardness and wear resistance in hard steel and high-strength materials
• 118-degree drill point angle for standard entry geometry across a broad range of metals
• Bright uncoated finish — no coating to compromise close-tolerance hole sizing or regrind cycles
• Right-hand cutting direction for use with standard drill press and CNC spindle rotation
• Web thickness of 0.015 inches for stable core support at small diameters
• Tight diameter tolerance of +0.0000 to -0.0005 inches for precise hole sizing

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide drill bit for applications involving hard steel and high-strength materials requiring a 1/16-inch hole diameter with a 118-degree point geometry.

Installation Notes

This bit should be installed and operated by qualified machinists or maintenance professionals familiar with carbide tooling. Carbide is brittle — avoid lateral loading, interrupted cuts without proper setup, or use in hand-drill applications where flex and vibration can cause fracture. Verify spindle runout and collet or chuck condition before use, as even minor runout at this diameter accelerates premature breakage. Follow applicable workplace safety standards for rotating tooling and machine guarding.
