Hertel 89324362 Taper Shank Drill Bit 57/64 in 3MT Hss

Product Description

The HERTEL 89324362 is a taper shank drill bit designed for high-speed steel drilling applications in metal fabrication, machining, and general industrial work. It measures 57/64 inch (0.8906 inch decimal) in diameter and features a No. 3 Morse taper shank for secure, self-centering mounting in compatible spindles and drill presses. The 118-degree point angle is the standard geometry for general-purpose drilling in steel, cast iron, and non-ferrous metals. An oxide finish provides basic lubricity and corrosion resistance. Licensed machinists and tool-and-die professionals are the primary installers and operators of this bit.

This bit is suited for production drilling and general-purpose hole-making in machine shop environments, maintenance facilities, and metal fabrication shops. The No. 3 Morse taper shank fits drill press spindles, lathes, and milling machines equipped with a 3MT socket or sleeve. At 10.75 inches overall length with a 6.125-inch flute, it handles moderate depth-to-diameter drilling tasks in both ferrous and non-ferrous workpiece materials.

Key Features

• 57/64 inch diameter with 0.8906 inch decimal equivalent for precision sizing
• No. 3 Morse taper (3MT) shank for self-centering, high-torque drive engagement
• 118-degree point angle for general-purpose drilling across common metal types
• High-speed steel construction maintains edge integrity under standard cutting speeds
• Oxide finish reduces friction and provides light corrosion protection
• 6.125-inch flute length supports chip evacuation in moderate-depth holes

Compatibility

Designed for use in drill press spindles, lathe tailstocks, and milling machine quills equipped with a No. 3 Morse taper socket or a 3MT sleeve adapter.

Installation Notes

Installation and operation should be performed by qualified machinists or trained shop personnel. Always power down and lock out the machine before seating or removing the taper shank. Ensure the taper socket and shank are clean and free of chips or burrs before insertion to achieve full contact and prevent slippage. A drawbar or drift key appropriate to the machine should be used for proper seating and removal.
