Hertel 89323109 Taper Shank Drill Bit 3-3/16 in 5MT Hss

Product Description

The HERTEL 89323109 is a large-diameter taper shank drill bit engineered for general-purpose drilling in metal and industrial materials. It accepts a No. 5 Morse taper shank, making it compatible with heavy-duty drill presses and milling machines equipped with 5MT spindles. The cutting end features a 118-degree point angle suited for drilling into most ferrous and non-ferrous metals. Manufactured from high-speed steel with an oxide finish, the bit provides adequate heat and wear resistance for production environments. At 3.1875 inches in diameter, this is a heavy industrial tool intended for machine-tool operators and maintenance machinists working in fabrication, manufacturing, or heavy industrial maintenance settings.

This bit is designed for stationary machine-tool applications where a 5MT taper spindle is available. Typical installations include large floor-standing drill presses, radial arm drills, and milling machine setups used in industrial fabrication shops, shipyards, and heavy equipment maintenance facilities. The 14.625-inch flute length accommodates deep-hole drilling passes, and the 24.5-inch overall length is suited to machines with adequate quill or spindle travel to handle this size.

Key Features

• No. 5 Morse taper shank fits 5MT spindle sockets on heavy-duty drill presses and mills
• 118-degree point angle for general-purpose drilling in ferrous and non-ferrous metals
• High-speed steel construction provides heat resistance during high-load cuts
• Oxide finish reduces friction and offers basic corrosion resistance
• 14.625-inch flute length supports deep-hole drilling passes

Compatibility

Designed for use in machine tools equipped with a No. 5 Morse taper spindle socket, including heavy-duty floor drill presses and radial arm drill presses configured for large-diameter tooling.

Installation Notes

This drill bit is installed by a machinist or qualified machine-tool operator. Power down and lock out the machine before seating or removing the taper shank. Clean both the tool shank and spindle taper bore thoroughly before seating to ensure full contact and prevent slippage under load. Use a proper drift key and striking bar to safely eject the bit from the spindle — never strike the spindle housing directly.
