Century Drill Tool Co Inc 47337 Sd Drill Bit 37/64 in

Product Description

The CENTURY DRILL TOOL CO INC 47337 is a 37/64 inch Silver and Deming style drill bit designed for heavy-duty drilling through wood, soft metals, and hard metals. The bit features a 135-degree split point for accurate starts and reduced walking on contact. A high-speed steel construction with a black oxide finish provides two-tone surface treatment that reduces heat buildup and minimizes friction during extended drilling operations. The 1/2 inch reduced shank allows use with standard 1/2 inch drill chucks, making it compatible with a wide range of corded and cordless drill platforms. Each package contains 2 bits.

Silver and Deming drill bits are a staple on job sites where standard jobber-length bits cannot reach required diameters. The 47337 is suited for residential and light commercial applications including metalworking, woodworking, HVAC rough-in, plumbing penetrations, and general fabrication work. The reduced shank design makes oversized drilling accessible without requiring a dedicated large-capacity chuck. Tradespeople such as pipefitters, plumbers, HVAC installers, and electricians commonly keep S and D bits on hand for boring large-diameter holes through structural materials.

Installation Notes

Silver and Deming bits should be installed securely in a 1/2 inch keyed or keyless chuck before operation. Always ensure the workpiece is clamped or secured before drilling to prevent rotation and injury. Use appropriate cutting fluid when drilling through hard metals to extend bit life. Operate at the correct RPM for the material and bit diameter — larger diameter bits require lower speeds to avoid overheating the cutting edge.
