Overview

The NSI Industries SDS11821 SDS drill bit is a precision-engineered tool for heavy-duty masonry and concrete drilling. With a 1-1/8" diameter and 21" overall length, this bit delivers a 17" effective drilling depth, making it ideal for deep hole applications in construction, renovation, and infrastructure projects. The SDS shank ensures secure power transfer when paired with compatible SDS hammer drills, eliminating slippage and maximizing impact force for faster, cleaner drilling. Manufactured in the US by NSI Industries, this bit is built for durability and consistent performance in demanding conditions. Compatible with standard SDS-plus and SDS-max systems, it supports a wide range of hammer drills and rotary hammers.
