Hertel 89323463 Taper Shank Drill Bit 1-37/64 in 5MT Hss

Product Description

The HERTEL 89323463 is a taper shank drill bit designed for heavy-duty drilling in metal, ferrous materials, and other general-purpose industrial applications. Built from high-speed steel with an oxide finish, this bit measures 1-37/64 inches (1.5781 inches decimal) in diameter and seats into a No. 5 Morse taper spindle. The 118-degree drill point angle is the standard geometry for general-purpose drilling, providing a reliable center point and consistent chip evacuation. At 16-7/8 inches overall length with a 9-7/8 inch flute, this bit handles deep-hole drilling in larger workpieces. Machinists, tool-and-die workers, and maintenance professionals are the primary users.

This drill bit is suited for use in drill presses, lathes, and milling machines equipped with a No. 5 Morse taper spindle or sleeve. The large diameter makes it appropriate for boring holes in structural steel, plate, cast iron, and similar materials in machine shops, fabrication facilities, and heavy industrial maintenance environments. The oxide finish provides light lubricity and corrosion resistance during storage and use. It is sold individually and fits standard No. 5 Morse taper tool holders without adapters.

Key Features

• 1-37/64 inch (1.5781 inch) diameter for large-bore drilling applications
• No. 5 Morse taper shank for direct mounting in compatible spindles and holders
• 118-degree drill point angle for general-purpose drilling on a wide range of materials
• High-speed steel construction provides toughness and heat resistance during prolonged cuts
• Oxide finish offers light corrosion resistance and reduces friction at the cutting interface
• 9-7/8 inch flute length supports deep-hole drilling with adequate chip clearance

Compatibility

Designed for use in drill presses, lathes, and boring machines fitted with a No. 5 Morse taper spindle or a compatible sleeve adapter. Suitable for general-purpose drilling in ferrous and non-ferrous metals.

Installation Notes

Installation is performed by machinists or qualified maintenance personnel. Before mounting, ensure the machine spindle and taper shank are clean and free of chips or burrs to ensure full taper seating. Power down and lock out the machine before inserting or removing the bit. Use a drift key and proper drift slot to remove the bit safely — never strike the taper shank directly with a hammer.
