Strovolt Premium TCT Annular Core Cutter 68mm Diameter x 50mm Depth Tungsten Carbide Tipped Mag Drill Bit
Product Overview
The Strovolt STRO786850 is a professional-grade Tungsten Carbide Tipped (TCT) Annular Core Cutter engineered for heavy-duty hole making in industrial steel applications. With a robust 68mm cutting diameter and a 50mm cutting depth, this core drill bit is designed to bore through thick steel plates, girders, and pipes significantly faster and with greater precision than traditional twist drills.
Featuring advanced micro-grain carbide tips from premium manufacturers like Sandvik, the Strovolt TCT series offers superior thermal stability and wear resistance, ensuring prolonged tool life even in demanding environments. Its specialized multi-tooth geometry distributes the cutting load evenly, reducing vibration and ensuring smooth chip evacuation. This makes it the ideal choice for use with magnetic drilling machines (mag drills) in structural fabrication, shipbuilding, and heavy machinery repair.
The Strovolt 68x50mm TCT Annular Cutter is essential for large-scale fabrication projects involving structural steel components. It rapidly creates 68mm bolt holes in I-beams, H-beams, girders, and thick steel plates, significantly reducing production time compared to solid drilling. In the shipbuilding industry, it is indispensable for penetrating thick hull plates and bulkheads during new vessel construction or repair work. Additionally, it is widely used in the fabrication of mining equipment, cranes, earthmovers, and other heavy machinery, where it effortlessly cuts through high-tensile structural steel, stainless steel (INOX), and cast iron components.
One of the key advantages of this TCT core cutter is its ability to remove material only at the periphery, ejecting a solid slug or core. This process requires significantly less horsepower and time than solid drilling a 68mm hole, resulting in increased efficiency and productivity. Furthermore, the precision-ground cutting edges produce a reamer-quality, burr-free finish, eliminating the need for secondary grinding or deburring operations.
The Strovolt STRO786850 is constructed with a heat-treated, hardened alloy steel body designed to resist torsional stress and deformation, ensuring consistent performance and dimensional accuracy. The cutting tips are made from premium micro-grain tungsten carbide, renowned for its extreme hardness and wear resistance, enabling the tool to maintain its cutting edge even in abrasive environments.
With a standard 31.75mm (1-1/4") Weldon shank, this large-bore cutter is compatible with industry-standard magnetic drilling machines, ensuring a secure and stable connection capable of handling the high torque demands of heavy-duty drilling operations. Additionally, the TCT cutting technology allows for higher surface speeds than conventional high-speed steel (HSS) tools, further reducing production downtime and increasing overall efficiency.
Whether you're working on structural steel fabrication, pressure vessel construction, shipbuilding, or heavy machinery repair, the Strovolt STRO786850 Tungsten Carbide Tipped Annular Core Cutter is a reliable and high-performance solution for creating large, precise holes in even the toughest industrial materials.
