Hertel 89323174 Taper Shank Drill Bit 1-1/32 in 3MT Hss

Product Description

The HERTEL 89323174 is a taper shank drill bit designed for drilling large-diameter holes in metal, wood, and general-purpose materials. It carries a 1-1/32 inch (1.0313 inch decimal) cutting diameter and uses a No. 3 Morse Taper (3MT) shank for direct mounting in compatible taper-socket spindles, tailstocks, and drill press quills. The 118-degree point angle suits general-purpose drilling across a wide range of workpiece materials. Constructed from high-speed steel with an oxide finish, the bit resists heat buildup during extended cutting operations. Machinists, tool-and-die workers, and maintenance mechanics typically reach for this bit when a standard straight-shank drill cannot provide adequate torque transfer at larger diameters.

This bit fits production machining, maintenance repair, and fabrication environments where a 3MT taper socket is available on the machine spindle or drill press quill. The 6.5 inch flute length provides adequate chip clearance for moderate-depth holes, and the 11.125 inch overall length suits standard drill press and lathe tailstock setups. General-purpose applications include through-hole and blind-hole drilling in ferrous and non-ferrous metals, plastics, and similar industrial materials.

Key Features

• 1-1/32 inch (1.0313 inch) cutting diameter for large-bore hole production
• No. 3 Morse Taper shank for positive drive and easy quill removal with a drift key
• 118-degree point angle suits general-purpose drilling across common workpiece materials
• High-speed steel construction provides heat resistance during extended cutting cycles
• Oxide finish reduces friction at the cutting edge and provides light corrosion resistance
• 6.5 inch flute length supports effective chip evacuation in moderate-depth applications

Compatibility

Designed for use in any drill press, milling machine, or lathe tailstock equipped with a No. 3 Morse Taper socket. A 3MT-to-larger-taper sleeve adapter may be required when the machine spindle uses a larger taper designation.

Installation Notes

Installation and removal should be performed by a qualified machinist or maintenance mechanic. Power off and lock out the machine before seating or removing the bit. Clean the taper shank and socket thoroughly before insertion to ensure full contact and prevent slippage. Use a proper drift key and a soft mallet to drive the bit free from the socket — never strike the cutting end of the bit directly.
