Chicago-latrobe 53162 Taper Shank Drill Bit 31/32 in Hss 3MT

Product Description

The CHICAGO-LATROBE 53162 is a taper shank drill bit designed for heavy-duty drilling in metal, wood, and general-purpose materials. It accepts a Morse taper shank (3MT) for use in drill presses, lathes, and milling machines equipped with a matching spindle taper. The bit is manufactured from high speed steel with an oxide finish, measuring 31/32 inch (0.9688 inches) in diameter with an 11-inch overall length. A 118-degree standard point angle and right-hand spiral flute geometry make this a reliable choice for production and maintenance drilling across a wide range of shop and field applications.

This drill bit is suited for use in machine shop environments, metal fabrication facilities, and maintenance departments where a taper shank drill is required for larger-diameter hole work. The 3MT shank seats directly into compatible taper-bore spindles without a chuck, providing rigid tool holding for accurate, repeatable results. The regular spiral and web-thinned point reduce thrust and help initiate the cut cleanly, making this bit appropriate for both ferrous and non-ferrous materials in general-purpose production settings.

Key Features

• 31/32 inch diameter with a tight tolerance of +0.0000 to -0.0012 inches for accurate hole sizing
• 3MT (Morse Taper No. 3) shank for direct spindle mounting without a drill chuck
• High speed steel construction with oxide finish for wear resistance and corrosion protection
• 118-degree standard point angle with web-thinned geometry to reduce thrust and improve starting
• Right-hand cut, regular spiral flute with 6.375-inch flute length for efficient chip evacuation
• General-purpose Series 110 design suited for a broad range of materials and drilling applications

Compatibility

Designed for use in drill presses, lathes, and milling machines fitted with a No. 3 Morse Taper spindle bore.

Installation Notes

Installation and removal of taper shank drill bits should be performed by a qualified machinist or tool and die technician. Power down and lock out the machine before seating or removing the bit from the spindle. Use a proper drift key and soft mallet to eject the taper shank — do not use excessive force or strike the shank directly. Verify the taper bore is clean and free of chips or burrs before seating the bit to ensure full contact and prevent slippage during operation.
