Century Drill Tool Co Inc 47346 Sd Drill Bit 23/32 in

Product Description

The CENTURY DRILL TOOL CO INC 47346 is a 23/32-inch Silver and Deming style drill bit engineered for heavy-duty cutting in wood, soft metals, and hard metals. It features a 135-degree split point for fast, accurate starts with reduced walking on hard surfaces. The high-speed steel construction carries a two-tone black oxide finish that resists heat and friction buildup during demanding drilling operations. This package includes 2 bits and is sized for use with standard 1/2-inch chuck drill presses and heavy-duty hand drills. Licensed tradespeople and experienced machinists rely on this style of bit for larger-diameter hole work that exceeds standard jobber-length drill capacity.

The 47346 Silver and Deming bit is well-suited for drilling oversized holes in structural steel, plate metal, hardwood, and similar materials encountered in fabrication, maintenance, and construction trades. The 1/2-inch reduced shank allows full-size drill presses and 1/2-inch chuck power drills to accept this large-diameter bit without requiring a specialty chuck. The black oxide surface treatment provides lubricity and corrosion resistance, helping the cutting edges maintain performance across repeated use cycles on tough substrates.

Installation Notes

Silver and Deming bits should be installed and operated by experienced tradespeople familiar with metal-cutting drill press or heavy-duty hand drill procedures. Secure the workpiece with appropriate clamps or vise before drilling to prevent rotation. Use cutting fluid when drilling hard metals to reduce heat and extend bit life. Inspect the chuck and bit shank for secure seating before powering on the tool.
