Chicago-latrobe 53160 Taper Shank Drill Bit 15/16 in 3MT Hss

Product Description

The CHICAGO-LATROBE 53160 is a taper shank twist drill bit designed for heavy-duty hole-making in metal, fabrication, and general machining applications. Built from high speed steel with an oxide finish, it measures 15/16 inch (0.9375 inches) in diameter and carries a Morse Taper 3 (3MT) shank for direct mounting in compatible drill presses, lathes, and milling machines. The 118-degree standard point angle suits a broad range of materials, and the web-thinned tip reduces thrust and improves chip clearance at the start of the cut. Overall length is 10.75 inches with a flute length of 6.125 inches.

This bit is suited for production and job-shop environments where a rigid, non-adjustable taper shank connection is preferred over a straight shank. Typical applications include structural steel fabrication, machine shops, maintenance and repair operations, and toolroom work. The right-hand spiral flute with regular helix efficiently evacuates chips during through-hole and blind-hole drilling. It is a general-purpose tool appropriate for machinists, millwrights, ironworkers, and industrial maintenance technicians.

Key Features

• High speed steel construction for durability across a wide range of metals and general-purpose materials
• Oxide finish improves lubricity and provides mild corrosion resistance during storage and use
• 3MT taper shank seats directly in Morse Taper 3 spindles without a chuck
• 118-degree standard point angle with web thinning for reduced entry thrust and cleaner starts
• Right-hand, regular-helix spiral flute for efficient chip evacuation
• Series 110 designation indicates a standard-length, general-purpose geometry

Compatibility

Designed for use in drill presses, lathes, and milling machines equipped with a Morse Taper 3 spindle or sleeve. A reducing or extension sleeve may be required for spindles of a different Morse Taper designation.

Installation Notes

Installation is performed by machinists or millwrights. Power down and lock out the machine before inserting or removing the taper shank. Clean both the shank taper and the spindle socket thoroughly before seating to ensure full contact and prevent runout. Never force a mismatched taper into a spindle; use the correct drift key and knockout bar to remove the bit safely after use.
