Hertel 89324123 Taper Shank Drill Bit 2-17/32 in 5MT Hss

Product Description

The HERTEL 89324123 is a taper shank drill bit designed for boring large-diameter holes in metal, steel, and other hard materials. It carries a 2-17/32 inch (2.5313 inch decimal) cutting diameter and mounts via a No. 5 Morse taper shank, which seats directly into compatible taper-socket spindles on drill presses, lathes, and radial arm drills. The high-speed steel construction with an oxide finish provides wear resistance and heat tolerance during general-purpose drilling. A 118-degree point angle suits flat-starting applications in ferrous metals. The flute length runs 11.25 inches and the overall length is 18.75 inches.

This bit is suited for production and maintenance drilling operations in industrial and heavy trade environments. Machinists, tool-and-die shops, and maintenance mechanics reach for large-diameter taper shank bits when a straight-shank chuck cannot grip the required size. The No. 5 Morse taper is typically found on larger floor-model drill presses and machine tool spindles. This bit handles general-purpose material removal in ferrous stock and is sold as a single unit.

Key Features

• 2-17/32 inch (2.5313 inch) cutting diameter for large-bore applications
• No. 5 Morse taper shank for direct spindle mounting without a chuck
• 118-degree drill point angle for general-purpose drilling in ferrous metals
• High-speed steel construction tolerates elevated cutting temperatures
• Oxide finish adds surface hardness and mild corrosion resistance
• 11.25-inch flute length provides chip clearance in deep-hole work

Compatibility

Designed for use in machine tool spindles and drill press quills equipped with a No. 5 Morse taper socket. Confirm spindle taper designation before installation.

Installation Notes

Installation is performed by machinists or qualified maintenance mechanics. Power down and lock out the machine before seating or removing the taper shank. Clean both the shank taper and the spindle socket thoroughly before insertion to ensure full seating contact. Never use a chuck adapter smaller than the rated taper designation, and use a proper drift key and soft mallet to eject the bit safely.
