Chicago-latrobe 49703 3/64 in Taper Length Drill Bit Hss

Product Description

The CHICAGO-LATROBE 49703 is a taper length twist drill bit designed for general-purpose drilling in metal, wood, and similar materials. Built from high speed steel (HSS) with a coated finish, this bit measures 0.0469 inches (3/64 inch) in diameter and delivers a 118-degree standard point angle for reliable hole-starting without a center punch in most applications. The tapered web configuration and web-thinned geometry reduce cutting resistance and help clear chips efficiently. Overall length is 2.25 inches with a straight shank, making it compatible with standard drill chucks. Right-hand spiral flutes handle chip evacuation in typical through-hole and blind-hole drilling operations.

This drill bit is suited for light-duty production and maintenance drilling tasks encountered in HVAC fabrication, electrical rough-in, plumbing, and general metalworking. The 3/64-inch diameter is commonly used for pilot holes, sheet metal, and small-diameter through-holes in thin stock. The coated HSS construction holds up to repeated use in general-purpose shop and field environments. Each unit is sold individually, though the minimum order quantity is 12 pieces per order.

Installation Notes

Install into a properly sized drill chuck and tighten securely before use. Ensure the workpiece is clamped or fixtured to prevent movement during drilling. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life. Inspect the cutting edges for wear before each use and replace when the point shows signs of dulling or chipping.
