Chicago-latrobe 50732 Extra Length Drill Bit 0.2344 in Hss

Product Description

The CHICAGO-LATROBE 50732 is a 120X-series extra length drill bit designed for long reach drilling in ferrous and cast iron materials. Built from high speed steel with an oxide finish, this bit measures 0.2344 inches in diameter with a 12-inch overall length and a 9-inch flute length, giving it the extended reach needed for deep-hole applications where standard-length bits fall short. The two-flute, right-hand spiral design with a notched 118-degree point and web-thinned, tapered web configuration delivers clean entry and efficient chip evacuation. This bit is suited for professional machinists, maintenance technicians, and metalworking tradespeople who routinely drill through thick stock or stacked material.

The 50732 is intended for long reach drilling applications in cast iron and steel workpieces. Its straight cylindrical shank, measuring 0.2344 inches in diameter and 3 inches in length, seats securely in standard drill chucks and collet holders. The regular spiral flute geometry promotes consistent chip removal during extended plunge operations, making this bit a practical choice for production environments, tool and die work, and heavy maintenance tasks where precision and reach are both required.

Key Features

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with metal drilling operations. Ensure the drill press, lathe, or handheld drill is fully powered down and the chuck is released before inserting or removing the bit. Secure the shank fully in the chuck or collet to the specified gripping depth before operating, and verify chuck key removal prior to starting the spindle. Always wear appropriate eye protection and follow applicable workplace safety standards when drilling cast iron or steel.
