Strovolt Premium TCT Annular Core Cutter 71mm Diameter x 50mm Depth Tungsten Carbide Tipped Mag Drill Bit

The Strovolt Premium TCT Annular Core Cutter (Part No: STRO787150) is a heavy-duty, large-diameter drilling solution designed for rapid, precision boring through thick steel plates, structural beams, and pipes. Boasting a substantial 71mm cutting diameter and 50mm cutting depth, this industrial-grade core drill bit outperforms traditional twist drills in speed, efficiency, and finish quality.

Engineered for the toughest job sites, the Strovolt TCT Cutter features premium micro-grain tungsten carbide tips welded to a hardened alloy steel body, enabling superior thermal stability and smooth penetration even under high torque loads. Its advanced multi-tooth geometry reduces vibration, optimizes chip evacuation, and delivers a clean, burr-free finish in a single pass—eliminating the need for pilot or step drilling.

This versatile 71x50mm annular cutter is essential for heavy fabrication, infrastructure projects, and metal drilling applications across industries. In structural steel fabrication, it rapidly creates large anchor holes and bolt patterns in bridge girders, columns, and base plates. For pressure vessels, tanks, and shipbuilding, it effortlessly penetrates thick-walled pipes, storage tanks, hull plates, and bulkheads. In heavy machinery manufacturing, it is indispensable for drilling components of mining equipment, cranes, and earthmovers. With its exceptional hardness and wear resistance, it cuts through stainless steel (INOX), cast iron, and high-tensile structural steel with ease.

Combining advanced engineering, premium materials, and a robust 31.75mm (1-1/4") Weldon shank designed to handle high torque, the Strovolt Premium TCT Annular Core Cutter delivers unmatched performance, efficiency, and productivity for large-diameter drilling operations in demanding industrial environments.
