Hertel 89324321 Taper Shank Drill Bit 53/64 in 3MT Hss

Product Description

The HERTEL 89324321 is a taper shank drill bit designed for drilling precise, clean holes in metal and general-purpose materials. It features a 53/64-inch diameter (0.8281 inches decimal), a 3 Morse Taper shank for secure seating in compatible spindles and drill presses, and a 118-degree point angle suited for a wide range of workpiece materials. The bit is manufactured from high-speed steel with an oxide finish that provides corrosion resistance and reduces friction during cutting. Overall length is 10.75 inches with a flute length of 6.125 inches, giving adequate chip clearance on deeper cuts. Machinists, tool-and-die workers, and maintenance technicians are the typical end users.

This drill bit is used in machine shop, manufacturing, and maintenance environments where a Morse Taper spindle is present. Typical applications include drilling through mild steel, cast iron, aluminum, and similar materials on drill presses, lathes, and milling machines equipped with a 3MT socket. The 118-degree general-purpose point geometry makes it suitable for production drilling and repair work alike. It is sold as a single unit.

Key Features

• 53/64-inch diameter (0.8281 inches) for precise hole sizing
• 3 Morse Taper shank seats securely in 3MT-compatible spindles without a separate chuck
• 118-degree point angle provides general-purpose performance across a broad range of metals
• High-speed steel construction maintains hardness and edge retention at elevated cutting temperatures
• Oxide finish reduces friction and offers mild corrosion protection
• 6.125-inch flute length supports chip evacuation on deeper holes

Compatibility

Designed for use in drill presses, lathes, and milling machines equipped with a 3 Morse Taper spindle or sleeve. A 3MT-to-smaller-taper adapter sleeve is required if the machine spindle is a different Morse Taper size.

Installation Notes

Installation is performed by machinists or maintenance technicians familiar with Morse Taper tooling. Before seating or removing the bit, ensure the machine is fully powered down and the spindle has come to a complete stop. Clean both the taper shank and the spindle socket of chips and oil before seating to ensure full contact and prevent slippage. Use a drift key through the spindle slot to remove the bit; do not strike the spindle housing directly.
