Overview

NSI Industries TCT238S is a shallow-cut tungsten carbide hole cutter engineered for precision work on sheet metal, metal plate, stainless steel, and aluminum. With a 2-3/8" cutting diameter and 3/16" cutting depth, this tool delivers clean, burr-free holes in thin materials without deep penetration. The 3/8" arbor size ensures compatibility with standard drill chucks and power tools, making it a versatile addition to any metalworking setup. Unlike deep-cut hole cutters, the shallow-cut design minimizes material waste and reduces the risk of warping or distortion in thin-gauge metals. Ideal for HVAC, electrical, and general fabrication applications where clean entry and exit points are critical. The TCT238S is built for durability and repeatable performance in high-volume production environments. Its tungsten carbide construction provides extended tool life, resisting wear from abrasive materials like stainless steel and aluminum. The 3/16" cutting depth is specifically optimized for thin materials, preventing over-cutting while maintaining hole integrity. The 3/8" arbor size matches common drill chuck sizes, allowing seamless integration with corded drills, drill presses, and magnetic base drills without requiring adapters. Backed by NSI Industries' reputation for industrial-grade cutting tools, the TCT238S is designed for professionals who demand consistent results. It excels in applications requiring frequent hole cutting, such as ductwork fabrication, electrical panel installation, and metal enclosure assembly. The cutter's shallow profile also reduces the risk of tool deflection, ensuring straighter, more accurate holes compared to deeper-cut alternatives. With a focus on efficiency and precision, the TCT238S is a reliable choice for workshops and production lines where downtime and material waste must be minimized.
