Chicago-latrobe 49705 Taper Length Drill Bit 5/64 in Hss

Product Description

The CHICAGO-LATROBE 49705 is a taper length twist drill bit designed for precision drilling in general-purpose metalworking applications. Manufactured from high speed steel with a coated finish, this bit measures 5/64 inch (0.0781 inches) in diameter and features a standard 118-degree split point with web thinning to reduce walking and improve centering on entry. The spiral flute geometry and tapered web configuration promote efficient chip evacuation during drilling. At 3-3/4 inches overall length with a 2-inch flute, the taper length format provides extended reach compared to jobber-length bits while maintaining rigidity. Machinists, toolroom technicians, and maintenance tradespeople rely on this bit for consistent performance on ferrous metals.

This drill bit is suited for use in drill presses, CNC machining centers, and hand-held power drills where a straight shank is required. It is optimized for drilling alloy steel, carbon steel, and cast iron in both production and maintenance repair environments. The right-hand cut spiral flute configuration is compatible with standard right-hand spindle rotation. The Series 120 designation places this bit in CHICAGO-LATROBE general-purpose tooling line, appropriate for shop environments handling a variety of ferrous workpieces at moderate cutting speeds.

Key Features

• High speed steel construction for durability across alloy steel, carbon steel, and cast iron
• 118-degree standard point angle with web thinning for improved entry and reduced thrust
• Coated finish to extend tool life and reduce friction during cutting
• 2-inch spiral flute length promotes chip evacuation in deeper holes
• Straight shank at 0.0781 inches diameter fits standard drill chucks without adapters
• Tapered web configuration maintains core strength through the full flute length

Compatibility

Designed as a general-purpose replacement or stock drill bit for standard 3-jaw drill chucks accepting straight shank bits at 5/64 inch (0.0781 inches) diameter. Suitable for use in drill presses, CNC equipment, and portable power drills operating with right-hand spindle rotation.

Installation Notes

Installation and use of this drill bit should be performed by machinists or qualified tradespeople familiar with proper tooling practices. Secure the straight shank firmly in a calibrated chuck before operation and verify runout is within acceptable tolerance. Ensure the workpiece is clamped securely and the spindle speed is appropriate for the material and diameter being drilled. Disconnect power to the machine before changing or inspecting tooling.
