Strovolt Premium TCT Annular Core Cutter 46mm Diameter x 50mm Depth Tungsten Carbide Tipped Mag Drill Bit Heavy Duty Structural Steel Cutter
Product Overview
The Strovolt STRO784650 is a premium Tungsten Carbide Tipped (TCT) Annular Core Cutter engineered for heavy-duty drilling in demanding industrial environments. Boasting a substantial 46mm cutting diameter and an extended 50mm cutting depth, this professional-grade core drill bit is the ultimate solution for boring clean, large-diameter holes in tough metals, including Stainless Steel, Cast Iron, Hardened Steel, and exotic alloys.
Unlike traditional twist drills that require massive horsepower, heavy feed pressure, and time-consuming pre-drilling, the Strovolt TCT Annular Cutter revolutionizes the drilling process by cutting only the periphery of the hole and ejecting a solid slug. This innovative geometry significantly reduces energy consumption, minimizes wear on your magnetic drill, and delivers a burr-free finish in seconds, making it indispensable for production environments where tool life and speed are critical.
Engineered with Advanced Micro-Grain Carbide Tips, the STRO784650 withstands higher temperatures and abrasion than High-Speed Steel (HSS) cutters, ensuring superior performance and extended tool life. The Triple-Edge Geometry features a specialized 3-ply tooth geometry (inner, middle, outer) that splits the chip load, reducing cutting resistance and preventing chatter, which is crucial when drilling larger diameters like 46mm.
The Strovolt 46mm x 50mm TCT Cutter is a versatile workhorse for a wide range of applications in fabrication and heavy industry. In structural steel applications, it is essential for drilling 46mm clearance holes for large anchor bolts in I-beams, columns, and base plates. It is also ideal for creating tapping holes or inlets in thick-walled pipes, flanges, and pressure vessels in process piping applications. For heavy machinery repair, it is used for re-boring pivot points and mounting holes on excavators, cranes, and mining equipment. Additionally, it effortlessly cuts through Stainless Steel (INOX), Hardox, and high-tensile structural steel (St52), making it perfect for hard alloy fabrication projects. The Strovolt TCT Cutter is also an excellent choice for construction projects, such as bridge retrofitting and railway infrastructure, where on-site drilling is required.
The STRO784650 features a precision 19.05mm (3/4") Weldon Shank, ensuring a secure fit in all major magnetic drill brands, including Alfra, Hougen, Evolution, Nitto, and Euroboor. Its precision internal bore facilitates smooth slug ejection immediately after the cut is complete, ensuring efficient operation and minimizing downtime.
With its high thermal stability, the Strovolt TCT Cutter is capable of dry drilling in cast iron or high-speed drilling in steel without losing temper hardness. It delivers a reamer-quality finish (Ra 3.2), often eliminating the need for deburring, saving time and increasing productivity.
The STRO784650 is constructed with the highest quality materials for superior performance and durability. The cutting tips are made of K-Grade Micro-Grain Tungsten Carbide (Sandvik equivalent), chosen for their optimal balance of hardness and toughness to resist impact fracture. The body is constructed from high-strength Heat-Treated Alloy Steel, engineered to absorb torsional vibration and prevent shank breakage. The carbide tips are securely bonded to the body using a silver-alloy brazing process, ensuring they remain secure even under extreme heat and intermittent cutting stress.
With its exceptional cutting capabilities, versatility, and robust construction, the Strovolt STRO784650 Premium TCT Annular Core Cutter is a must-have tool for any professional fabricator, machinist, or industrial contractor demanding high-performance and efficiency when drilling large-diameter holes in tough materials.
