Hertel 89323901 Taper Shank Drill Bit 33/64 in 2MT Hss

Product Description

The HERTEL 89323901 is a taper shank drill bit designed for general-purpose drilling in metal, wood, and similar materials. It features a 33/64-inch (0.5156-inch decimal) diameter, a No. 2 Morse taper (2MT) shank for secure seating in compatible drill presses and milling machines, and a 118-degree point angle suited to a wide range of workpiece materials. Constructed from high-speed steel with an oxide finish, the bit resists heat buildup and light corrosion during normal shop use. Licensed machinists, tool-and-die technicians, and maintenance professionals are the typical end users for this style of bit.

This bit is intended for use in drill presses, lathes, and milling machine spindles equipped with a No. 2 Morse taper socket. The 33/64-inch diameter is a standard fractional size commonly called for in through-hole and clearance-hole applications across general manufacturing and maintenance environments. The 118-degree split point angle starts cleanly on flat and curved surfaces without a center punch on most metals. With a 4-5/8-inch flute length and an 8-1/2-inch overall length, this bit handles moderate-depth holes in a single pass without the need for peck-drilling on typical workpiece thicknesses.

Key Features

• 33/64-inch diameter (0.5156 inches decimal) for standard fractional clearance and through-hole applications
• No. 2 Morse taper (2MT) shank seats securely in compatible drill press and lathe spindles without a separate chuck
• 118-degree point angle provides broad compatibility with ferrous and non-ferrous metals
• High-speed steel construction maintains cutting edge integrity at elevated operating temperatures
• Oxide finish reduces friction and offers light corrosion resistance during storage and use
• 4-5/8-inch flute length allows chip evacuation on moderate-depth holes

Compatibility

Designed for use in any drill press, lathe tailstock, or milling machine spindle accepting a No. 2 Morse taper (2MT) tooling socket. General-purpose fitment for standard fractional drill applications in maintenance, manufacturing, and fabrication settings.

Installation Notes

Installation and removal of Morse taper tooling should be performed by a qualified machinist or toolroom technician. Ensure the spindle and taper shank are clean and free of chips or burrs before seating the bit — debris on the taper surfaces causes runout and premature wear. Use a proper drift and mallet to eject the bit from the spindle socket; do not pry against the flutes. Power down and lock out the machine before any tooling change.
