Hertel 83245795 Solid Carbide Spade Drill Bit 7/64 Inch

Product Description

The HERTEL 83245795 is a solid carbide spade drill bit designed for drilling into hard steel and high strength materials where standard high-speed steel bits fail or wear prematurely. It measures 7/64 inch (0.1094 inches) in diameter with an overall length of 1-1/2 inches and a flute length of 7/16 inch. The 118-degree point angle is a standard geometry suited for flat entry into metallic workpieces, while the 10-degree body included angle and 0.015-inch web thickness support rigidity and chip clearance. The bright, uncoated finish maintains dimensional accuracy and suits applications where coating buildup would compromise tight tolerances. Right-hand cutting direction. Installed by machinists and tool-and-die professionals in CNC and manual drilling operations.

This bit is intended for use in ferrous metals and high-strength alloys, including hardened steels and similar difficult-to-machine materials. The solid carbide construction provides the rigidity needed to maintain accuracy in deep or interrupted cuts where flex in the tool body would cause drift or premature failure. Typical applications include precision hole-making in manufacturing, maintenance, and production environments where consistent diameter tolerance is critical. The compact overall length of 1-1/2 inches makes it well suited for tight-clearance fixturing and short-reach spindle setups.

Key Features

• Solid carbide construction resists wear in hard steel and high-strength alloys
• 118-degree point angle provides standard flat-entry geometry for metallic workpieces
• Bright uncoated finish maintains diameter tolerance of +0.0000 to -0.0005 inches
• 10-degree body included angle and 0.015-inch web thickness support rigidity and chip flow
• Right-hand cutting direction compatible with standard spindle rotation
• Compact 1-1/2 inch overall length suits tight-clearance and short-reach applications

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide spade drill bit for standard drill chucks and collet holders accepting 7/64 inch shank diameters in CNC machining centers, drill presses, and manual lathes operating on hard steel and high-strength material workpieces.

Installation Notes

This bit should be installed and operated by qualified machinists or tooling professionals familiar with carbide tooling handling. Secure the shank fully in a collet or chuck rated for the intended RPM before operation. Solid carbide is brittle — avoid side loading, interrupted cuts at high feed rates without proper setup, or dropping the tool on hard surfaces. Follow your machine manufacturer's recommended speeds and feeds for carbide tooling in the workpiece material being drilled.
