Hertel 83245845 Solid Carbide Spade Drill Bit 7/32 in

Product Description

The HERTEL 83245845 is a solid carbide spade drill bit ground to a 118-degree included point angle and sized at 7/32 inches (0.2188 inches) in diameter. Built from solid carbide stock with a bright polished finish, this bit delivers tight diameter tolerances of +0.0000 to -0.0005 inches, making it suitable for precision drilling operations where hole size consistency matters. Overall length is 2 inches with a flute length of 19/32 inches. Licensed HVAC technicians, machinists, and maintenance trades use spade-style carbide bits when working with hard steel and high-strength materials that would rapidly dull high-speed steel tooling.

This bit is rated for use in hard steel and high-strength material applications where carbide cutting geometry is required to maintain edge integrity. The short overall length of 2 inches and compact flute geometry make it well suited for confined-space drilling operations and benchtop drill press work on ferrous and alloy stock. It is sold individually as a single-piece unit.

Key Features

• Solid carbide construction resists wear when drilling hard steel and high-strength alloys
• 118-degree spade point angle for positive centering and reduced thrust
• Bright polished finish reduces friction and aids chip evacuation
• Tight diameter tolerance of +0.0000 to -0.0005 inches for consistent hole sizing
• Compact 2-inch overall length suits tight-clearance drilling setups
• Single-piece packaging with no minimum order requirement beyond one unit

Compatibility

Designed as an OEM-style replacement or aftermarket option for standard 7/32-inch spade drill bit applications in drill presses, CNC equipment, and hand-held drilling operations on hard steel and high-strength materials.

Installation Notes

Carbide drill bits are brittle and should be handled carefully to avoid chipping the cutting edge prior to use. Secure the workpiece firmly before drilling and ensure the spindle is properly aligned to prevent lateral loading, which can fracture carbide tooling. Use appropriate cutting fluid or coolant when drilling hard or high-strength steel to extend tool life and maintain dimensional accuracy. Inspect the cutting edge before each use and replace if chipping or edge wear is observed.
