Hertel 89324347 Taper Shank Drill Bit 3 in 5MT Hss

Product Description

The HERTEL 89324347 is a large-diameter taper shank drill bit designed for heavy-duty drilling in metal, steel, and similar materials. Built from high-speed steel (HSS) with an oxide finish, this bit delivers consistent performance in general-purpose machining applications. The 3-inch diameter and 5 Morse taper (5MT) shank make it suited for large floor-standing drill presses, radial arm drills, and boring mills that accept MT5 spindles. The 118-degree point angle provides a versatile cutting geometry for a wide range of ferrous and non-ferrous workpieces. Machinists and toolroom technicians rely on this size class for production drilling, jig work, and structural fabrication where a standard jobber-length bit cannot reach the required depth.

This bit is intended for use in industrial and commercial machine shop environments. The 14-inch flute length accommodates deep-hole applications where chip evacuation and coolant access are critical concerns. The 21.75-inch overall length provides ample clearance in deep-bored setups. It is typically installed and operated by journeyman machinists, tool and die makers, or structural fabricators working with large spindle machines. The oxide finish offers light corrosion resistance during storage and helps with initial lubrication at the cutting edge during use.

Key Features

• 3-inch diameter cutting edge for large-bore drilling operations
• 5 Morse taper (5MT) shank for positive drive and easy removal with a drift key
• 118-degree point angle suits general-purpose drilling in a broad range of materials
• 14-inch flute length supports deep-hole drilling with improved chip clearance
• High-speed steel construction maintains cutting hardness under elevated heat
• Oxide finish provides light corrosion resistance and surface lubricity

Compatibility

Designed for use in drill presses, radial arm drills, and milling machines equipped with a No. 5 Morse taper (5MT) spindle socket.

Installation Notes

Installation requires a machine spindle with a No. 5 Morse taper socket; ensure the taper socket is clean and free of chips or burrs before seating the shank. Power down and lock out the machine before inserting or removing the bit. A drift key and mallet are the standard tools for ejecting a Morse taper shank from the spindle. Use appropriate cutting fluid for the workpiece material to extend tool life and manage heat buildup at the cutting edge.
