Strovolt Premium TCT Annular Core Cutter 75mm Diameter x 50mm Depth Tungsten Carbide Tipped Mag Drill Bit Part No: STRO787550

The Strovolt STRO787550 is a heavy-duty 75mm Diameter x 50mm Depth Tungsten Carbide Tipped (TCT) Annular Core Cutter engineered for extreme drilling performance in industrial steel fabrication. With its substantial cutting dimensions, this core drill bit is designed to bore large holes through thick steel plates, structural beams, and pipes with unmatched speed and precision.

Featuring premium micro-grain carbide tips welded to a hardened alloy steel body, the Strovolt TCT Annular Cutter series is built to handle the high torque and heat generated during large-diameter drilling. 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 core cutter is essential for heavy industrial applications such as structural fabrication, creating anchor holes and bolt patterns in bridge girders, columns, and base plates. It's ideal for drilling large inlets/outlets in thick-walled pipes, pressure vessels, and storage tanks in the oil and gas industry. In shipbuilding, it effortlessly penetrates thick hull plates and bulkheads. The STRO787550 is also invaluable for the fabrication of mining equipment, cranes, earthmovers, and other heavy machinery, easily cutting through stainless steel, cast iron, and high-tensile structural steel.

With its 31.75mm (1-1/4") Weldon shank, industry-standard for cutters over 60mm to handle high torque, the Strovolt TCT Annular Cutter operates at higher surface speeds than HSS tools, reducing production downtime. Its annular design removes material only at the periphery, ejecting a large solid slug/core, requiring significantly less horsepower and time than solid drilling a 75mm hole.
