Hertel 89323042 Taper Shank Drill Bit 2-3/16 in 5MT Hss

Product Description

The HERTEL 89323042 is a taper shank drill bit designed for drilling large-diameter holes in metal and other rigid materials. It features a 2.1875-inch (2-3/16 inch) diameter cutting edge, a No. 5 Morse Taper (5MT) shank for secure registration in compatible spindles and tailstocks, and a 118-degree point angle suited for general-purpose drilling on a wide range of workpiece materials. The tool is manufactured from high-speed steel with an oxide finish that provides a measure of corrosion resistance and reduces friction during cutting. Overall length is 17.375 inches with a flute length of 10.25 inches. This bit is installed by machinists, tool-and-die tradespeople, and industrial maintenance technicians.

This drill bit is intended for general-purpose production and maintenance drilling where a large-diameter hole is required in a single pass or as a finishing step after piloting. The 5MT taper shank seats directly into Morse taper spindles found on drill presses, lathes, radial arm drills, and similar machine tools. The oxide finish makes it appropriate for use with cutting fluids or in dry drilling conditions on ferrous and non-ferrous metals, plastics, and similar structural materials.

Key Features

• 2-3/16 inch (2.1875 inch) cutting diameter for large-bore applications
• No. 5 Morse Taper shank for positive self-holding engagement in compatible spindles
• 118-degree point angle for general-purpose drilling across common workpiece materials
• High-speed steel construction provides hardness and heat resistance during extended cuts
• Oxide finish reduces surface friction and offers basic corrosion resistance
• 10.25-inch flute length supports chip evacuation in deep-hole drilling

Compatibility

Designed for use in machine tool spindles and tailstocks that accept a No. 5 Morse Taper shank, including drill presses, engine lathes, and radial arm drilling machines equipped with a 5MT socket or sleeve.

Installation Notes

Installation and removal must be performed with the machine powered down and the spindle fully stopped. The taper shank and receiver socket should be wiped clean and free of chips or oil before seating to ensure proper engagement and runout control. A Morse taper drift and drift slot should be used for safe removal — never use a hammer blow directly on the shank body. Operators should select appropriate cutting speeds and feeds for the workpiece material and apply cutting fluid where recommended to extend tool life.
