Overview

NSI Industries NHSD43E is a precision-engineered high-speed steel (HSS) twist drill designed for professional metalworking applications, including aerospace, automotive, and industrial fabrication. This #43 drill bit features a 118-degree tip angle, optimized for efficient chip evacuation and reduced walking during drilling operations, which enhances accuracy in tight-tolerance applications. The black oxide finish provides superior wear resistance and lubricity, extending tool life by up to 50% compared to uncoated drills in high-production environments. With an overall length of 2-1/4 inches and a 1/8" shank size, this drill is engineered for confined spaces and precision work in sheet metal, aluminum, brass, and mild steel, delivering consistent performance in both manual and CNC machining operations. The HSS construction maintains cutting edge integrity at elevated temperatures up to 1000°F, ensuring durability in demanding conditions. The specific geometry of the NHSD43E reduces burr formation by 30% and minimizes secondary finishing operations, making it ideal for fabricators, machinists, and maintenance professionals requiring reliable, medium-duty drilling solutions. NSI Industries, a trusted name in metalworking tools, includes this drill in their specialized cutting tool lineup, meeting industrial drilling requirements where repeatable performance and tight tolerances are critical.
