Overview

The NSI Industries SD1231678 Step Drill is a high-performance carbon steel M2 tool designed for precision drilling in metal studs, switch boxes, junction boxes, lighting fixtures, and other thin-gauge metal applications. This 2-flute split tip step drill features a 3/16" to 7/8" hole size range with 1/16" increments across 12 steps, enabling clean, burr-free holes without pre-punching. The 3/8" shank with three flats ensures a non-slip grip in drill chucks, while the self-drilling design eliminates the need for pilot holes in 10-gauge mild or stainless steel. Engineered for durability and efficiency, this step drill delivers consistent results in electrical, HVAC, and general fabrication work. Compatible with standard 3/8" drill drivers, it’s ideal for contractors and tradespeople seeking a versatile, time-saving solution for metalworking tasks. Made in the USA, the SD1231678 combines M2 high-speed steel for extended tool life and polished flutes for fast chip evacuation.
