Chicago-latrobe 68833 Taper Length Drill Bit 33/64 in Hss

Product Description

The CHICAGO-LATROBE 68833 is a taper length drill bit designed for heavy-duty metal drilling in production and maintenance machining environments. Built from high speed steel with a bright uncoated finish, it features a 135-degree split point that self-centers on contact, reducing the need for a center punch and minimizing walking on hard surfaces. The parabolic flute geometry improves chip evacuation at higher feed rates, making it well suited for deeper holes where chip packing is a concern. At 0.5156 inches (33/64 inch) in diameter with an 8-inch overall length, this bit bridges the gap between jobber and extra-length drills for applications requiring greater reach without sacrificing rigidity.

The 68833 is intended for drilling alloy steel, carbon steel, aluminum, and other non-ferrous metals. The taper length configuration and tanged shank are matched to drill press chucks and spindles that accept taper-mount tooling, common in industrial shop floors, tool rooms, and heavy maintenance operations. The split point and heavy-duty grade designation make it appropriate for interrupted cuts and harder workpiece materials where a standard jobber bit would deflect or wear prematurely. Machinists and maintenance technicians working on structural components, fixtures, or equipment frames will find this bit a practical fit.

Key Features

• 135-degree split point for self-centering entry without a center punch
• Parabolic flute profile for efficient chip evacuation in deep holes
• High speed steel construction rated for alloy steel, carbon steel, aluminum, and non-ferrous metals
• Tanged shank for positive drive and secure seating in taper-mount spindles
• Tapered web configuration adds core strength and extends tool life under heavy feeds
• Bright uncoated finish — suitable for use with cutting fluid or dry as required by the application

Compatibility

Designed as an OEM-style replacement or direct-use taper length drill bit compatible with drill press spindles and taper-mount chucks accepting a 1/2-inch tanged shank. Rated for use in alloy steel, carbon steel, aluminum, and non-ferrous metals per manufacturer material application data.

Installation Notes

This bit is installed by machinists or maintenance technicians in taper-mount drill press spindles or compatible milling machine fixtures. Ensure the spindle and chuck are fully seated and the machine is powered down before changing tooling. Secure the tanged shank fully before operation to prevent slippage under torque. Use appropriate cutting fluid for steel applications to manage heat and extend tool life.
