Hertel 89324354 Taper Shank Drill Bit 61/64 in 3MT Hss

Product Description

The HERTEL 89324354 is a taper shank drill bit designed for general-purpose metal drilling in industrial and shop environments. Built from high-speed steel with an oxide finish, this bit measures 61/64 inches (0.9531 inches) in diameter and seats into a No. 3 Morse taper spindle. The 118-degree point angle is the standard geometry for drilling into mild steel, cast iron, aluminum, and similar materials. With an overall length of 11 inches and a flute length of 6.375 inches, it reaches depth requirements that straight-shank bits typically cannot. Machinists and toolroom technicians are the primary users.

This drill bit is suited for use in drill presses, lathes with tailstock chucks, and milling machines equipped with a No. 3 Morse taper spindle. It is a general-purpose tool appropriate for production drilling and maintenance operations in metal fabrication, tooling, and manufacturing environments. The oxide finish provides a degree of surface hardness and lubricity that helps extend service life during standard drilling cycles.

Key Features

• 61/64 inch diameter (0.9531 inches decimal) for precise hole sizing
• No. 3 Morse taper shank for secure, self-holding spindle engagement
• 118-degree split point angle — standard geometry for general-purpose metal drilling
• High-speed steel construction handles elevated cutting temperatures
• Oxide finish reduces friction and provides corrosion resistance during storage
• 6.375-inch flute length supports deeper hole drilling applications

Compatibility

Designed for use in any machine spindle or tailstock accepting a No. 3 Morse taper shank, including standard drill presses, engine lathes, and milling machines configured for 3MT tooling.

Installation Notes

Installation is performed by machinists or qualified toolroom personnel. Before inserting the bit, ensure the machine is fully powered down and the spindle is at rest. Clean the taper shank and the spindle socket thoroughly — any chips or debris will prevent full seating and can cause runout. Drive the taper shank home with a firm, controlled strike using a soft mallet; removal requires a drift key through the spindle slot. Follow applicable shop safety protocols and machine manufacturer guidelines for spindle speeds appropriate to the material and bit diameter.
