Chicago-latrobe 50333 Taper Length Drill Bit 0.0890 in Hss

Product Description

The CHICAGO-LATROBE 50333 is a taper length drill bit designed for precision drilling in ferrous metals and general-purpose machining applications. Built from high speed steel with a coated finish, this bit measures 0.0890 inches in diameter and carries a standard 118-degree drill point angle. The tapered web configuration and web-thinned tip reduce cutting resistance and improve centering accuracy. At 4.25 inches overall length with a 2.25-inch spiral flute, it offers more reach than a jobber-length bit while maintaining rigidity. Right-hand cut with a straight shank, it fits standard drill chucks without adapters. Machinists, maintenance technicians, and tool-and-die workers are the typical installers.

This bit is suited for drilling alloy steel, carbon steel, and cast iron in production and maintenance environments. The Series 120 taper length geometry is a common choice when jobber-length bits lack the reach for deeper hole applications or when a longer flute length is needed to clear chips effectively. The 0.0890-inch diameter corresponds to wire gauge size No. 43, making it a standard reference size for tapping and clearance hole work in light steel fabrication and repair shops.

Key Features

• 0.0890 inch diameter, wire gauge size No. 43 for standard tapping and clearance applications
• 118-degree standard point angle with web-thinned, tapered web for reduced entry force
• High speed steel construction with coated finish for wear resistance
• Spiral flute, regular spiral type promotes effective chip evacuation
• 4.25 inch overall length provides extended reach versus standard jobber bits
• Right-hand cut, straight shank fits conventional drill chucks and spindles

Compatibility

Designed for use in alloy steel, carbon steel, and cast iron. Compatible with any standard drill chuck or spindle accepting a 0.0890 inch straight shank. General-purpose fitment for bench drills, drill presses, and CNC drilling applications requiring wire gauge No. 43 diameter.

Installation Notes

Secure the shank fully in the drill chuck before operation and verify concentricity to avoid bit deflection. Use appropriate cutting fluid or coolant when drilling steel to extend tool life and maintain dimensional tolerance. Inspect the cutting edges for wear before each use, especially when drilling hardened alloy steels. Follow applicable shop safety standards and machine guarding requirements during operation.
