Hertel 89323752 Taper Shank Drill Bit 1-23/32 in 5MT Hss

Product Description

The HERTEL 89323752 is a taper shank drill bit engineered for heavy-duty drilling in metal, cast iron, and similar ferrous materials. Built from high-speed steel with an oxide finish, it delivers consistent performance in general-purpose production and maintenance machining environments. The bit measures 1-23/32 inches (1.7188 inches decimal) in diameter, carries a 5 Morse taper shank for direct mounting in compatible machine spindles, and features a standard 118-degree drill point angle suited to a wide range of workpiece materials. Machinists, tool-and-die technicians, and maintenance mechanics are the primary users of this class of tooling.

This bit is appropriate for use in drill presses, lathes, milling machines, and radial arm drills equipped with a 5MT spindle taper. The 10-1/8 inch flute length accommodates deep-hole applications where chip evacuation over a long travel distance is required. With an overall length of 17-1/8 inches, it fits large-capacity machine tools commonly found in industrial shops and heavy maintenance facilities. General-purpose oxide finish provides basic lubricity and corrosion resistance during storage and cutting.

Key Features

• 1-23/32 inch (1.7188 inch) drill diameter for large-bore applications
• 5 Morse taper shank for direct, rigid mounting in 5MT machine spindles
• 118-degree drill point angle for general-purpose metal drilling
• High-speed steel construction for durability across ferrous and non-ferrous materials
• Oxide finish provides basic corrosion resistance and reduces galling
• 10-1/8 inch flute length supports deep-hole chip evacuation

Compatibility

Designed for use in machine tool spindles with a No. 5 Morse taper socket, including drill presses, lathes, and radial arm drills that accept 5MT tooling.

Installation Notes

Installation and use of large taper shank drill bits should be performed by qualified machinists familiar with machine tool operation and cutting tool safety. Ensure the machine spindle is fully de-energized and at a complete stop before inserting or removing the taper shank. Clean both the shank taper and the spindle socket of chips, oil, and debris before seating to ensure proper contact and concentricity. Follow the machine manufacturer's recommended speeds and feeds for the workpiece material and drill diameter to avoid tool breakage.
