Overview

NSI Industries NHSD7 is a high-speed steel (HSS) twist drill engineered for precision drilling in ferrous and non-ferrous metals, including steel, aluminum, brass, and cast iron. This #7 drill size, with a 0.2010-inch diameter, features a 118° tip angle for clean entry and reduced burr formation, ensuring dimensional accuracy in medium-depth applications up to 1.5 inches. The bright finish provides corrosion resistance, while the 3-5/8" overall length delivers optimal reach for controlled chip evacuation in tight spaces. Supplied in a 10-piece pack, the NHSD7 reduces downtime from tool changes in general fabrication, maintenance, and repair work. Compatible with standard drill presses and handheld drills with 1/4" shank capacity, this HSS construction offers superior heat resistance and extended tool life compared to carbon steel drills. The drill’s precision-ground flutes enhance chip removal and reduce friction, improving efficiency in high-volume operations. Ideal for general-purpose metalworking tasks, including drilling pilot holes, countersinks, and through-holes in sheet metal, structural components, and machined parts. NSI Industries' precision engineering ensures reliable results across a range of applications, from automotive repairs to light industrial fabrication.
