Chicago-latrobe 50403 Taper Length Drill Bit 0.2420 in

Product Description

The CHICAGO-LATROBE 50403 is a taper length drill bit designed for general-purpose drilling in ferrous metals and industrial materials. Built from high speed steel with a coated finish, this bit measures 0.2420 inches in diameter and carries a standard 118-degree point angle. The taper length body provides additional reach beyond a jobber-length bit without sacrificing rigidity, making it a practical choice for production drilling and maintenance work. Web thinning at the tip reduces thrust and improves cut initiation. Licensed tradespeople and industrial machinists reach for this bit when standard-length drills fall short.

This drill bit is suited for drilling into alloy steel, carbon steel, and cast iron in both shop and field environments. The straight shank accommodates standard drill chucks across a wide range of portable and stationary equipment. The right-hand spiral flute clears chips efficiently in through-hole and blind-hole applications. It is a fit for general machining, mechanical contracting, and fabrication scenarios where a reliable, mid-reach drill bit is required on a regular basis.

Key Features

• High speed steel construction for durability in steel and cast iron
• 118-degree standard point angle for general-purpose drilling
• Coated finish to extend cutting life and reduce friction
• Web-thinned tip reduces entry thrust and improves penetration
• Right-hand spiral flute with tapered web for efficient chip evacuation
• Straight shank compatible with standard drill chucks

Compatibility

Designed for use in alloy steel, carbon steel, and cast iron applications. Fits standard drill chucks accepting a 0.2420-inch straight shank. Series 120 taper length configuration.

Installation Notes

Installation and use are performed by machinists, millwrights, or qualified tradespeople using standard drill presses, lathes, or hand-held power drills. Secure the workpiece before drilling and verify chuck grip on the straight shank before operation. Wear appropriate eye protection and follow applicable shop safety protocols when drilling ferrous materials. Inspect the cutting edge before each use and replace the bit if chipping or wear is evident.
