Hertel 89324222 Taper Shank Drill Bit 1-1/64 in 3MT Hss

Product Description

The HERTEL 89324222 is a taper shank drill bit designed for drilling large-diameter holes in metal, cast iron, and similar materials. It carries a 3MT (Morse Taper 3) shank that seats directly into compatible drill press spindles and lathes, eliminating the need for a separate chuck on heavy-duty setups. The cutting diameter is 1-1/64 inches (1.0156 inches decimal), with a 118-degree point angle suited for general-purpose work on a wide range of workpiece materials. The body is ground from high-speed steel with an oxide finish that provides basic lubricity and corrosion resistance during storage and use.

This bit is intended for use in drill presses, lathes, and milling machines equipped with a No. 3 Morse Taper spindle socket. It fits general-purpose metalworking applications in machine shops, maintenance facilities, and industrial fabrication environments. The 6-1/2 inch flute length supports drilling deeper bores while maintaining chip evacuation, and the 11-1/8 inch overall length accommodates setups where extended reach is required. Machinists, tool-and-die workers, and maintenance mechanics are the primary installers.

Key Features

• 1-1/64 inch (1.0156 inch) cutting diameter for close-tolerance large-bore work
• No. 3 Morse Taper shank seats directly in compatible spindles without a chuck
• 118-degree point angle for general-purpose drilling across common metals
• High-speed steel construction for durability under moderate heat and cutting loads
• Oxide finish for basic corrosion resistance and reduced galling during use
• 6-1/2 inch flute length supports deep-hole drilling with adequate chip clearance

Compatibility

Designed for use in drill presses, lathes, and milling machines equipped with a No. 3 Morse Taper (3MT) spindle socket. Suitable for general-purpose drilling in ferrous and non-ferrous metals.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician. Ensure the machine spindle is fully de-energized and at rest before seating or removing the taper shank. Clean both the shank taper and the spindle socket of chips, oil, and debris before insertion to achieve proper seating and prevent runout. A drift pin and soft mallet are standard tools for ejecting the shank from the spindle after use.
