Strovolt Premium TCT Annular Core Cutter 42mm Diameter x 50mm Depth Tungsten Carbide Tipped Mag Drill Bit Hardened Steel & Inox Ready Part No: STRO784250
Product Overview
The Strovolt STRO784250 is a premium Tungsten Carbide Tipped (TCT) Annular Core Cutter engineered for heavy-duty drilling applications in the toughest industrial materials. With a precise 42mm cutting diameter and an extended 50mm cutting depth, this professional core drill bit is designed to bore through hardened steel, stainless steel, cast iron, titanium alloys, and other abrasive metals significantly faster, cooler, and with greater precision than standard High-Speed Steel (HSS) twist drills.
Unlike traditional drill bits that grind the entire surface area, the Strovolt TCT Annular Cutter removes material only at the periphery, ejecting a solid cylindrical slug at the end of the cut. This energy-efficient design requires less torque and horsepower, extending the life of your magnetic drilling machine. Featuring advanced Micro-Grain Tungsten Carbide tips rated for HRC 90+ hardness, the STRO784250 offers superior thermal stability, allowing it to maintain a sharp cutting edge even under extreme high-temperature drilling conditions where HSS bits would rapidly dull or fail.
Incorporating a sophisticated 3-Ply Cutting Geometry with outer, middle, and inner cutting edges, this annular cutter balances chip load, reduces vibration, and prevents chatter for a smoother, more controlled drilling experience. The precision-ground 19.05mm (3/4") Weldon Shank with two flats ensures a secure fit in almost all major magnetic drill brands, including Alfra, Hougen, Jancy, and Euroboor. The self-centering design allows the cutter to start cuts smoothly without walking, eliminating the need for pre-drilling or center punching.
With an extended tool life of up to 10 times longer than standard HSS cutters when drilling hard, abrasive materials, the Strovolt STRO784250 TCT Annular Core Cutter delivers exceptional value and productivity. Its superior performance makes it an essential tool for various industrial applications, including structural steel fabrication, pipe and pressure vessel manufacturing, hard metal machining, railway and transport maintenance, and bridge and infrastructure projects.
In structural steel fabrication, the 42mm diameter cutter rapidly creates holes for heavy-duty bolts, anchors, and threaded rods in I-beams, H-beams, and girders. For pipe and pressure vessel manufacturing, it is ideal for drilling clean, burr-free holes in thick-walled pipes, boiler tanks, and heat exchangers. In hard metal machining, it effortlessly cuts through difficult-to-machine materials like stainless steel (INOX), Hardox (wear plate), and high-tensile structural steel.
The cutter's capabilities extend to railway and transport applications, where it is essential for rail track maintenance, chassis manufacturing, and repairing heavy earthmoving equipment. It is also invaluable for bridge and infrastructure projects, where it is used for on-site drilling of rivet removals and structural reinforcements.
Engineered for demanding industrial environments, the Strovolt STRO784250 TCT Annular Core Cutter features a high-toughness alloy tool steel body heat-treated to resist torsional stress and prevent snapping under heavy loads. The carbide tips are induction brazed using a high-strength silver alloy to ensure they remain securely bonded, even under extreme thermal shock. The polished finish with oil-preserving flutes assists with lubrication and chip evacuation, while the optimized internal taper ensures reliable slug ejection after every cut.
With its exceptional performance, durability, and versatility, the Strovolt Premium TCT Annular Core Cutter is a must-have tool for fabrication shops, construction sites, and heavy industry maintenance operations that demand the highest levels of productivity and reliability.
