Chicago-latrobe 50313 Taper Length Drill Bit 0.154 in Hss

Product Description

The CHICAGO-LATROBE 50313 is a taper length, high speed steel twist drill bit designed for production and general-purpose drilling in metalworking applications. It carries a wire gauge size of 23, equal to 0.1540 inches in diameter, with a 118-degree standard point angle and a spiral flute configuration. The straight shank measures 0.1540 inches in diameter and seats directly into standard drill chucks. Web thinning at the tip reduces thrust and improves chip evacuation in tougher materials. This bit is suited for use by machinists, maintenance technicians, and metalworking tradespeople who need a reliable drill bit for repetitive, precise hole-making in steel and iron substrates.

This bit is intended for drilling alloy steel, carbon steel, and cast iron in shop, plant, and field maintenance environments. The taper length body provides greater reach than jobber-length bits, making it well suited for deeper hole applications or situations where standard-length bits fall short. The coated finish extends tool life in higher-cycle operations. It is sold individually but requires a minimum order quantity of 12 units per purchase.

Key Features

• High speed steel construction for general-purpose metalworking in alloy steel, carbon steel, and cast iron
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust
• 3.0-inch flute length with regular spiral geometry for efficient chip removal
• Coated finish for improved wear resistance and extended tool life
• Straight shank at 0.1540 inches diameter for direct chuck mounting with no adapter required
• Right-hand cut, taper length Series 120 configuration for deeper reach versus jobber-length alternatives

Compatibility

Designed for use in standard drill chucks accepting a 0.1540-inch straight shank. Suitable for drilling alloy steel, carbon steel, and cast iron as specified by the manufacturer for Series 120 general-purpose taper length drill bits.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trained metalworking technicians. Secure the straight shank firmly in a properly sized drill chuck before operation and confirm the workpiece is clamped or fixtured before drilling. Always wear appropriate eye protection and follow applicable machine shop safety procedures when operating drilling equipment. Do not exceed the rated material application range for this bit.
