Chicago-latrobe 50318 Taper Length Drill Bit 0.1405 in

Product Description

The CHICAGO-LATROBE 50318 is a taper length, straight-shank drill bit engineered for general-purpose drilling in metals and ferrous materials. Manufactured from high speed steel with an oxide finish, it features a 118-degree standard point angle and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. The bit measures 0.1405 inches in diameter, corresponding to wire size 28, with a 3-inch spiral flute length and an overall length of 5-3/8 inches. It is sold individually and is a right-hand-cut tool suited for use in standard drill presses, hand drills, and CNC setups where consistent hole quality is required in production or service environments.

This drill bit is designed for cutting alloy steel, carbon steel, and cast iron. The taper length body provides added rigidity over jobber-length bits, making it well suited for deeper holes where standard-length bits lack the reach or stability required. It fits any chuck accepting a straight shank and is appropriate for machine shops, fabrication facilities, HVAC rough-in work, plumbing rough-in, and general metal trades requiring a reliable wire-gauge drill in the 0.14-inch range.

Key Features

• High speed steel construction provides durability across alloy steel, carbon steel, and cast iron applications
• 118-degree standard point angle for general-purpose metal drilling
• Web-thinned, tapered web design reduces cutting thrust and improves chip flow
• Oxide finish enhances surface hardness and provides light corrosion resistance
• Taper length body (5-3/8 inches overall) offers extended reach beyond standard jobber-length bits
• Right-hand spiral flute for use with conventional clockwise-rotating spindles

Compatibility

Designed as a general-purpose taper length drill bit for use in standard straight-shank chucks. Rated for alloy steel, carbon steel, and cast iron material applications per Series 120 specifications.

Installation Notes

Install in a properly sized chuck and confirm the shank is fully seated and secured before operation. Power down or de-energize the drill press or machine tool before changing bits. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life, noting that this bit is not configured for coolant-through delivery. Follow applicable shop safety practices and wear eye protection during all drilling operations.
