Chicago-latrobe 50302 Taper Length Drill Bit 0.1890 in

Product Description

The CHICAGO-LATROBE 50302 is a taper length twist drill bit designed for general-purpose drilling in ferrous metals and alloys. Built from high speed steel (HSS) with a coated finish, it carries a standard 118-degree split point and a web-thinned, tapered web configuration that improves chip evacuation and reduces walking on entry. The straight shank measures 0.1890 inches in diameter, matching the cutting diameter, and the overall length is 6 inches with a flute length of 3.625 inches. This bit belongs to the Chicago-Latrobe Series 120 and is suited for production and maintenance drilling operations performed by machinists, millwrights, and general trade professionals.

The 50302 is rated for use in alloy steel, carbon steel, and cast iron. Right-hand spiral flutes evacuate chips efficiently during through-hole and blind-hole drilling. The bit does not require coolant through the shank, making it compatible with standard drill presses, lathes, or hand-held equipment where straight-shank tooling is accepted. Taper length geometry provides additional rigidity compared to jobber-length bits of the same diameter, making it a practical choice when drilling deeper holes or when added reach is needed in confined locations.

Key Features

• 0.1890 inch cutting diameter, Wire Size 12 designation
• 118-degree standard point angle with web-thinned tapered web for easier starting
• High speed steel construction with coated finish for extended service life
• Right-hand cut, regular spiral flute for efficient chip removal
• Taper length body at 6 inches OAL provides added reach and rigidity over jobber-length equivalents
• Straight shank, no threading — compatible with standard chucks and collets

Compatibility

Designed for use in alloy steel, carbon steel, and cast iron applications. Fits any standard drill chuck or collet accepting a 0.1890 inch straight shank. Suitable for drill presses, manual lathes, and hand-held drilling equipment as part of the Chicago-Latrobe Series 120 general-purpose line.

Installation Notes

This bit should be installed by a machinist or qualified trade professional using a properly sized chuck or collet. Ensure the drilling machine is powered down and locked out before changing tooling. Diameter tolerance is +0.0000 to -0.0007 inches, so verify fit with gauging if close-tolerance hole sizing is required. Do not exceed the recommended feed and speed parameters for the workpiece material to avoid premature tip wear or bit breakage.
