Hertel 83245902 Solid Carbide Spade Drill Bit 7/16 in

Product Description

The HERTEL 83245902 is a solid carbide spade drill bit designed for drilling hard steel and high-strength materials where standard high-speed steel tooling falls short. It features a 118-degree drill point angle and a 20-degree body included angle, geometry that promotes clean entry and controlled chip formation in demanding ferrous applications. The bright, uncoated finish maintains tight dimensional tolerances straight from the factory. With an overall length of 2-3/4 inches and a flute length of 1-3/16 inches, this bit is sized for precision short-hole work on CNC machining centers, drill presses, and manual lathes in production and maintenance environments.

This drill bit is suited for machining operations on hard steel, high-strength alloys, and similarly tough ferrous materials. Its 0.4375-inch diameter and right-hand cutting direction make it a standard fit for production shops, tool rooms, and industrial maintenance applications where carbide tooling is required to achieve consistent hole quality and acceptable tool life. It is sold and packaged individually, making it practical for both single-job replacement and batch procurement.

Key Features

• Solid carbide construction provides rigidity and wear resistance for hard and high-strength steel applications
• 118-degree drill point angle for efficient penetration and reduced thrust in ferrous materials
• Bright, uncoated finish with a tight diameter tolerance of +0.0000 to -0.0005 inches
• Right-hand cutting direction, compatible with standard drill press and CNC spindle rotation
• 2-3/4 inch overall length with 1-3/16 inch flute length for short-hole drilling precision
• Web thickness of 0.05 inches for core strength without excessive drilling resistance

Compatibility

Designed as an OEM-style solid carbide drill bit for use in drilling hard steel and high-strength materials; confirm spindle speed and feed rate compatibility with your specific machine tool setup before use.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with carbide tooling requirements. Ensure the drill chuck or collet is clean and properly torqued to the machine manufacturer's specification before seating the bit. Carbide is brittle compared to high-speed steel — avoid lateral loading, interrupted cuts without proper setup, or drop impacts that can chip the cutting edge. Consult your machine tool's feed and speed charts for the appropriate parameters when drilling hard or high-strength steel.
