Chicago-latrobe 50341 Taper Length Drill Bit 0.0670 in

Product Description

The CHICAGO-LATROBE 50341 is a taper length, straight-shank drill bit designed for precision drilling in ferrous metals and general-purpose metalworking applications. The bit measures 0.0670 inches in diameter, corresponding to Wire Gauge #51, and is manufactured from high speed steel with a coated finish for improved wear resistance. The 118-degree standard point angle is a versatile geometry suited to a wide range of materials. The spiral flute configuration and web-thinned, tapered web design promote efficient chip evacuation and reduce entry resistance. Cutting direction is right-hand. This bit is sold individually and is typically purchased by machinists, tool and die technicians, and maintenance tradespeople working on precise small-diameter hole applications.

The 50341 fits into production and maintenance drilling operations involving alloy steel, carbon steel, and cast iron workpieces. The taper length body provides additional reach compared to jobber-length bits of the same diameter, making it well suited to deeper hole applications where a standard-length bit would fall short. The straight shank is compatible with standard drill chucks and collet-style toolholding found on drill presses, lathes, and hand-held power drills. Series 120 construction reflects a general-purpose grade intended for everyday shop and field use rather than specialized high-production tooling.

Key Features

• Wire Gauge #51 diameter: 0.0670 inches with a tight tolerance of +0.0000 to -0.0005 inches
• High speed steel construction with coated finish for enhanced wear resistance
• 118-degree standard point angle for general-purpose entry into steel and cast iron
• Spiral flute, web-thinned tapered web for efficient chip removal and reduced thrust
• Taper length body at 3.75 inches overall with a 2-inch flute length for extended reach
• Right-hand cut, straight shank — fits standard drill chucks without adapters

Compatibility

Designed for use in alloy steel, carbon steel, and cast iron applications. The straight shank at 0.0670 inches diameter is compatible with standard drill chucks and collet holders sized to accept small-diameter tooling in that range.

Installation Notes

Installation and use should be performed by qualified machinists or tradespeople familiar with small-diameter drill bits. Secure the workpiece firmly before drilling to prevent walking or bit deflection at this diameter. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and maintain hole tolerance. Inspect the cutting edges before each use — small-diameter bits are susceptible to breakage if run at incorrect feeds or speeds.
