Chicago-latrobe 50448 Extra Length Drill Bit 3/32 in Hss

Product Description

The CHICAGO-LATROBE 50448 is a Series 120X extra length high speed steel drill bit designed for long reach drilling in ferrous metals and cast iron. The bit measures 0.0938 inches in diameter with an 8-inch overall length, giving it the extended reach needed to bore through deep sections or access confined workspaces that standard-length bits cannot reach. The oxide finish reduces friction and improves chip evacuation. A notched, web-thinned point at 118 degrees reduces entry thrust and starts cleanly without center-punching on most materials. Two spiral flutes with a tapered web configuration keep the bit running straight through the cut.

This bit is suited for metalworking applications in manufacturing, maintenance, and fabrication shops where standard jobber-length bits fall short. The 5.5-inch flute length and straight-cylindrical shank make it compatible with standard drill chucks on drill presses, lathes, and hand-held power drills. Primary workpiece materials listed by the manufacturer are cast iron and steel. The long reach design makes it a practical choice for structural steel work, heavy plate fabrication, and deep-hole operations in machine frames or weldments.

Key Features

• 0.0938 inch diameter with 8-inch overall length for deep-reach drilling
• High speed steel construction rated for cast iron and steel workpieces
• 118-degree notched, web-thinned point reduces entry thrust and improves centering
• Oxide finish lowers friction and helps resist heat buildup during cutting
• Straight-cylindrical shank fits standard 3-jaw drill chucks
• Right-hand cutting, two-flute spiral design with tapered web configuration

Compatibility

Designed as an OEM-style general-purpose extra length drill bit for use in standard drill chucks; compatible with drill presses, CNC drilling machines, and hand-held power drills accepting a 0.0938-inch straight-cylindrical shank.

Installation Notes

Installation and use should be performed by a qualified machinist or skilled trades professional. Secure the shank fully in the chuck and verify runout before drilling. Coolant-through operation is not supported on this bit; use cutting fluid applied externally when drilling steel to extend tool life and manage heat. Observe applicable shop safety standards and ensure the workpiece is clamped securely before beginning the cut.
