Strovolt Premium TCT Annular Core Cutter 41mm Diameter x 50mm Depth Tungsten Carbide Tipped Mag Drill Bit Heavy Duty Metal Cutter
Product Overview
The Strovolt STRO784150 is a premium TCT (Tungsten Carbide Tipped) Annular Core Cutter engineered for heavy-duty industrial drilling applications. Designed with a 41mm cutting diameter and an impressive 50mm depth of cut, this high-performance core drill bit effortlessly bores clean, accurate holes through the toughest metals, including stainless steel, cast iron, hardened steel, and exotic alloys.
Unlike conventional twist drills that require significant horsepower and generate excessive wear, the Strovolt TCT Annular Cutter optimizes the drilling process by cutting only the periphery of the hole, ejecting a solid slug at the end of the cut. This innovative geometry drastically reduces energy consumption and wear on your magnetic drilling machine while delivering a superior, burr-free finish in a fraction of the time compared to standard High-Speed Steel (HSS) bits.
Engineered with Advanced Micro-Grain Carbide Tips, the STRO784150 boasts exceptional hardness (HRC 90+) and thermal stability, enabling dry drilling in cast iron or high-speed drilling in steel without compromising temper hardness or edge integrity. The specialized triple-edge tooth geometry splits the chip load, minimizing cutting resistance and preventing chatter for a smoother, more controlled drilling experience.
One of the standout features of this TCT Annular Cutter is its universal compatibility. Equipped with a precision 19.05mm (3/4") Weldon Shank, it ensures a secure fit in all major magnetic drill brands, including Alfra, Hougen, Evolution, Nitto, and Euroboor. The precision internal bore facilitates smooth slug ejection immediately after the cut is complete, enhancing productivity and minimizing downtime.
The Strovolt 41mm x 50mm TCT Cutter is a versatile workhorse for a wide range of fabrication and heavy industry applications. In structural steel projects, it is essential for drilling 41mm clearance holes for large anchor bolts in I-beams, columns, and base plates. For process piping, it is ideal for creating tapping holes or inlets in thick-walled pipes, flanges, and pressure vessels. In 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 invaluable for hard alloy fabrication. The cutter is also perfect for bridge retrofitting and railway infrastructure projects requiring on-site drilling.
Constructed with meticulous attention to detail, the Strovolt STRO784150 features a high-strength, heat-treated alloy steel body engineered to absorb torsional vibration and prevent shank breakage. The cutting tips are made from premium K-Grade Micro-Grain Tungsten Carbide (Sandvik equivalent), chosen for their optimal balance of hardness and toughness to resist impact fracture. The tips are securely bonded to the body using a silver-alloy brazing process, ensuring they remain firmly attached even under extreme heat and intermittent cutting stress.
With its impressive performance specifications, including a reamer-quality surface finish (Ra 3.2), compatibility with internal cooling systems, and drilling speeds up to 3 times faster than HSS annular cutters and 10 times faster than twist drills, the Strovolt STRO784150 TCT Annular Core Cutter is a game-changer for fabricators and industrial professionals seeking maximum productivity, precision, and tool longevity.
