Chicago-latrobe 50493 Extra Length Drill Bit 0.2812 in Hss

Product Description

The CHICAGO-LATROBE 50493 is an extra length drill bit designed for long-reach drilling applications in metal fabrication, maintenance, and industrial trades. Built from high speed steel (HSS) with an oxide finish, it provides solid wear resistance in demanding cutting environments. The bit measures 0.2812 inches in diameter with an 8-inch overall length, giving technicians and machinists the extended reach needed to bore holes in deep cavities, structural members, or hard-to-access workpiece locations. A notched point and web-thinned construction reduce entry force and improve chip clearance on start-up. The 118-degree drill point angle is a standard general-purpose geometry suited for a wide range of ferrous materials.

This bit is intended for use in cast iron and steel workpieces across general-purpose drilling tasks. It fits within the Series 120X product line and suits shops, maintenance crews, and field technicians who need extended reach beyond what a jobber-length bit can provide. The spiral flute design promotes consistent chip evacuation during through-hole and deep-bore operations. The straight-cylindrical shank is compatible with standard three-jaw drill chucks found on bench drills, drill presses, and hand-held electric drills. Typical users include machinists, pipefitters, ironworkers, and maintenance mechanics working on steel and cast iron structures.

Key Features

• High speed steel construction delivers durability in steel and cast iron applications
• Oxide finish improves surface hardness and provides basic corrosion resistance
• Notched point and web-thinned design reduce thrust requirements and improve centering
• 118-degree drill point angle suits general-purpose ferrous material drilling
• Right-hand spiral flute with tapered web promotes efficient chip removal

Compatibility

Designed as a general-purpose extra length drill bit for use in steel and cast iron workpieces. Fits standard three-jaw drill chucks accepting a 0.2812-inch straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with drill press and rotary tool operation. Secure the workpiece firmly before drilling and ensure the chuck is properly tightened on the straight-cylindrical shank before operation. Always wear appropriate eye protection and follow applicable shop safety standards when operating cutting tools. Do not exceed the recommended feed rate or spindle speed for the workpiece material to avoid premature bit wear or breakage.
