Hertel 89323216 Taper Shank Drill Bit 1-1/16 in 3MT Hss

Product Description

The HERTEL 89323216 is a taper shank drill bit designed for drilling large-diameter holes in metal, wood, and general-purpose materials. It features a 1-1/16 inch cutting diameter, a 3 Morse Taper (3MT) shank for positive engagement in compatible drill press spindles and lathes, and a 118-degree point angle suited for a wide range of common materials. The bit is manufactured from high-speed steel (HSS) with an oxide finish that provides mild lubricity and corrosion resistance during storage and use. With an overall length of 11-1/4 inches and a flute length of 6-5/8 inches, it handles moderate-depth drilling applications in shop and field environments.

This drill bit is intended for general-purpose machining and metalworking applications. It is well suited for use in drill presses, milling machines, and engine lathes equipped with a 3MT spindle taper or sleeve adapter. Typical applications include through-hole and blind-hole drilling in mild steel, cast iron, aluminum, and similar workpiece materials. Machinists, toolroom technicians, and maintenance mechanics working in manufacturing, fabrication, and industrial maintenance settings are the primary users of this bit size and taper designation.

Key Features

• 1-1/16 inch (1.0625 inch) cutting diameter for large-bore hole making
• 3 Morse Taper (3MT) shank seats directly in compatible machine spindles without a separate chuck
• 118-degree point angle provides self-centering geometry suitable for general-purpose drilling
• High-speed steel construction maintains cutting edge integrity at elevated drilling temperatures
• Oxide finish offers mild corrosion resistance and reduces galling during initial cuts
• 6-5/8 inch flute length supports chip evacuation in moderate-depth holes

Compatibility

Designed for use in drill presses, lathes, and milling machines with a 3 Morse Taper spindle or a sleeve adapter that accepts a 3MT shank. No specific model compatibility was provided by the manufacturer for this part number.

Installation Notes

Installation is performed by machinists or maintenance mechanics familiar with Morse taper tooling. Ensure the spindle bore and taper shank are clean and free of chips or burrs before seating the bit — debris will cause misalignment and taper damage. Power down and lock out the machine before inserting or removing the bit. Use a drift key in the spindle slot to safely eject the taper shank; never strike the bit directly.
