Hertel 89323851 Taper Shank Drill Bit 1-19/32 in 5MT Hss

Product Description

The HERTEL 89323851 is a taper shank drill bit designed for drilling large-diameter holes in metal and other hard materials. It measures 1-19/32 inches (1.5938 inches decimal) in diameter and features a Number 5 Morse taper shank for secure seating in compatible taper-socket spindles and drill press quills. The 118-degree point angle suits general-purpose drilling across a broad range of workpiece materials. Constructed from high-speed steel with an oxide finish, the bit offers adequate heat and wear resistance for production and maintenance drilling applications. Licensed machinists, toolroom technicians, and maintenance mechanics are the typical installers.

This bit is suited for general-purpose metal drilling in manufacturing, fabrication, and maintenance environments. The 5MT shank fits large floor-standing drill presses, radial arm drills, and milling machine spindles equipped with a Number 5 Morse taper socket. With a flute length of 9-7/8 inches (9.875 inches) and an overall length of 16-7/8 inches (16.875 inches), the bit handles deep-hole drilling tasks where standard jobber-length bits cannot reach. It is sold individually and is a direct-use bit requiring no additional adapters beyond a matching 5MT socket.

Installation Notes

This bit is installed by licensed machinists or qualified maintenance personnel. Always power down and lock out the machine before seating or removing the taper shank. Clean both the shank and the socket bore before insertion to ensure full taper contact and prevent fretting. Use a drift key and drift slot to remove the bit safely — never strike the spindle housing directly.
