Chicago-latrobe 68811 Taper Length Drill Bit 11/64 in

Product Description

The CHICAGO-LATROBE 68811 is a taper length drill bit designed for demanding metal-cutting applications in industrial and trade environments. Manufactured from high speed steel (HSS) with a bright/uncoated finish, it measures 11/64 inch (0.1719 inches) in diameter and spans 5.75 inches in overall length. The 135-degree split point promotes self-centering on contact, reducing the need for a center punch on flat stock. A parabolic flute geometry improves chip evacuation and lowers cutting resistance during deeper passes. This bit is part of the CHICAGO-LATROBE Series 120DH heavy-duty line and is appropriate for use by machinists, maintenance technicians, and trade professionals working with metal substrates.

The 68811 is engineered for right-hand cutting in alloy steel, carbon steel, aluminum, and other non-ferrous metals. The taper length configuration provides additional reach compared to a standard jobber bit, making it well suited for drilling in recessed areas or where a longer flute length is required to clear chips effectively. The 4.125-inch flute length and tanged shank contribute to stability in taper-shank drill press spindles and compatible chucks. This bit is a single-piece, individually packaged unit suited for shop use, field maintenance, or toolroom inventory.

Compatibility

Suitable for use in alloy steel, carbon steel, aluminum, and non-ferrous metals. Compatible with taper-shank drill press spindles and chucks that accept an 11/64 inch tanged shank. Part of the CHICAGO-LATROBE Series 120DH heavy-duty taper length drill bit line.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with drill press and hand-drill operation. Secure the workpiece before drilling and ensure the spindle or chuck is properly tightened before starting the tool. Inspect the shank and flutes for damage or wear before each use. Follow applicable shop safety standards and equipment manufacturer guidelines when selecting cutting speeds and feeds for the workpiece material.
