Chicago-latrobe 50455 Extra Length Drill Bit 0.1094 in Hss

Product Description

The CHICAGO-LATROBE 50455 is a Series 120X extra length high speed steel drill bit built for long reach drilling applications. The bit measures 0.1094 inches in diameter with an 8-inch overall length, giving technicians and machinists the extended reach needed to bore through deep cavities, stacked materials, or confined workspaces that standard length bits cannot access. The oxide finish provides light corrosion resistance during storage and reduces friction at the cutting edge. With a 118-degree notched point angle and web-thinned, tapered web construction, the bit centers reliably and requires less thrust to penetrate the workpiece.

This drill bit is designed for right-hand cutting in cast iron and steel, making it a practical choice for HVAC, mechanical, and industrial trades that regularly drill through ferrous materials on the job. The straight-cylindrical shank seats directly in standard drill chucks without adapters. The 5.5-inch spiral flute length evacuates chips efficiently during deep-hole operations. It is sold individually and fits general purpose production and maintenance drilling where a longer reach is required.

Key Features

• Extra length design at 8 inches OAL enables long reach drilling in deep or obstructed workspaces
• 118-degree notched point with web thinning reduces thrust and improves centering on ferrous materials
• High speed steel construction withstands heat generated during steel and cast iron drilling
• Oxide finish provides light surface protection and reduces chip welding
• Straight-cylindrical shank fits standard 3-jaw drill chucks without additional tooling
• Diameter tolerance held to +0.0000 to -0.0005 inches for consistent hole sizing

Compatibility

Designed for general purpose long reach drilling in cast iron and steel workpieces. Fits any standard drill chuck accepting a 0.1094-inch straight-cylindrical shank.

Installation Notes

Installation and use of this bit should be performed by a qualified machinist or trade professional familiar with drilling operations on ferrous materials. Secure the shank fully in the drill chuck and verify concentricity before operation. Always wear appropriate eye and face protection when drilling metal. Follow applicable workplace safety standards and equipment manufacturer guidelines for spindle speed selection based on material and diameter.
