Hertel 83245894 Solid Carbide Spade Drill Bit 13/32 in

Product Description

The HERTEL 83245894 is a solid carbide spade drill bit designed for drilling into hard steel and high-strength materials where standard high-speed steel tooling falls short. It features a 118-degree point angle, a bright polished finish, and a drill bit diameter of 0.4062 inches (13/32 inches) with a tight diameter tolerance of +0.0000 to -0.0005 inches. Overall length is 2.75 inches with a flute length of 1.125 inches. This bit is suited for machinists, tool-and-die technicians, and metalworking professionals who require close-tolerance hole-making in demanding materials.

This drill bit is intended for use in ferrous metals, hard steels, and high-strength alloys where carbide cutting geometry is necessary to maintain dimensional accuracy and tool life. It is appropriate for use in drill presses, CNC machining centers, and manual milling machines in industrial, manufacturing, and job-shop environments. Its compact overall length makes it a practical choice for applications requiring rigid, short-reach tooling setups.

Key Features

• Solid carbide construction provides superior hardness and wear resistance compared to HSS in hard-steel applications
• 118-degree point angle with 20-degree body included angle for accurate entry and consistent chip formation
• Bright polished finish reduces friction and aids chip evacuation
• Tight diameter tolerance of +0.0000 to -0.0005 inches supports close-tolerance hole requirements
• Compact 2.75-inch OAL with 1.125-inch flute length for rigid short-reach setups

Compatibility

Designed as an OEM-style solid carbide spade drill bit suitable for use in standard drill chucks and collet-style toolholders that accept a 13/32-inch shank in drill presses, CNC machining centers, and milling machines rated for carbide tooling.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling technician familiar with carbide tooling requirements. Ensure the machine spindle and toolholder are clean and properly seated before securing the bit to prevent runout. Carbide tooling is brittle and susceptible to chipping under interrupted cuts or excessive lateral load — do not use in hand drills or unstable fixturing. Follow your machine manufacturer guidelines for feed rate and spindle speed when working with carbide drill bits in hard materials.
