Hertel 89323315 Taper Shank Drill Bit 1-43/64 in 5MT Hss

Product Description

The HERTEL 89323315 is a taper shank drill bit designed for drilling large-diameter holes in metal and other industrial materials. It accepts a No. 5 Morse taper (5MT) shank, fitting directly into compatible spindles, tailstocks, and drill press quills without an adapter. The cutting end features a 118-degree point angle suited for general-purpose drilling in a wide range of ferrous and non-ferrous materials. The bit is manufactured from high-speed steel (HSS) with an oxide finish that provides moderate lubricity and corrosion resistance during service. At 1-43/64 inches (1.6719 inches) in diameter, this is a heavy-duty tool intended for production and maintenance machining environments.

This drill bit is used in machine shops, maintenance and repair operations, and industrial production settings where large-diameter holes are required. It is suited for use in floor-standing drill presses, radial arm drills, lathes, and milling machines equipped with a No. 5 Morse taper socket. The general-purpose 118-degree point geometry makes it appropriate for drilling mild steel, cast iron, aluminum, and similar workpiece materials. Machinists, toolroom technicians, and industrial maintenance professionals are the primary installers and operators of this tool.

Key Features

• 1-43/64 inch (1.6719 inch) drill diameter for large-bore applications
• No. 5 Morse taper (5MT) shank for direct spindle mounting without a sleeve adapter
• 118-degree drill point angle for general-purpose cutting in common metals
• High-speed steel construction provides durability and heat resistance during drilling
• Oxide finish offers moderate lubricity and surface protection
• 10-1/8 inch flute length supports deep-hole drilling with adequate chip clearance

Compatibility

Designed for use in machines equipped with a No. 5 Morse taper spindle or socket, including floor-standing drill presses, radial arm drills, and lathe tailstocks configured for 5MT tooling.

Installation Notes

Installation is performed by machinists or maintenance technicians familiar with Morse taper tooling. Clean both the taper shank and the spindle socket thoroughly before seating to ensure full contact and prevent fretting. Never use a hammer to seat or remove the shank — use a drift key in the spindle drift slot for proper removal. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit.
