Hertel 02387868 Reduced Shank Drill Bit 7/8 in Hss

Product Description

The HERTEL 02387868 is a reduced shank drill bit engineered for general-purpose drilling in low and medium tensile strength materials. It features a 7/8 inch cutting diameter with a reduced 1/2 inch straight-cylindrical shank, allowing it to fit standard 1/2 inch drill chucks without requiring a larger chuck capacity. The bit is manufactured from high-speed steel (HSS) with an oxide finish for basic corrosion resistance. Overall length is 6 inches with a 3 inch flute length and a 118-degree standard point angle. Right-hand spiral flutes evacuate chips efficiently during through-hole and blind-hole drilling operations. Machinists, maintenance technicians, and fabricators are the typical users.

This bit is suited for drilling in low and medium tensile strength materials including mild steel, aluminum, plastics, and similar workpiece materials. The reduced shank design makes it particularly useful when a large-diameter hole is needed but only a 1/2 inch chuck is available, a common situation on portable drill presses, hand drills, and light-duty drill presses found in maintenance and production environments. The 3 inch maximum drilling depth accommodates most standard thickness stock and structural members encountered in field and shop applications.

Key Features

• 7/8 inch cutting diameter with reduced 1/2 inch straight-cylindrical shank for standard chuck compatibility
• High-speed steel construction provides adequate hardness and toughness for ferrous and non-ferrous materials
• 118-degree standard point angle for general-purpose drilling across a wide range of materials
• Oxide finish provides basic surface protection against corrosion during storage and use
• Right-hand spiral flutes promote efficient chip evacuation during drilling
• 6 inch overall length with 3 inch flute length supports drilling to 3 inches maximum depth

Compatibility

Designed for use with 1/2 inch capacity drill chucks on portable drills, drill presses, and similar drilling equipment. Intended for low and medium tensile strength workpiece materials.

Installation Notes

Secure the shank fully in the chuck and verify the bit is centered before beginning drilling. Always power down and de-energize or unplug the drilling equipment before changing bits. Use appropriate workholding to secure the workpiece and prevent rotation during drilling. Eye protection and appropriate PPE should be worn in accordance with applicable shop safety standards.
