Strovolt Premium TCT Annular Core Cutter 43mm Diameter x 50mm Depth Tungsten Carbide Tipped Mag Drill Bit Hardened Steel & Inox Ready Part No: STRO784350
Product Overview
The Strovolt STRO784350 is a premium-grade Tungsten Carbide Tipped (TCT) Annular Core Cutter engineered for high-performance heavy-duty drilling applications. With a precise 43mm cutting diameter and an extended 50mm cutting depth, this professional core drill bit is designed to bore through the toughest industrial metals—including Stainless Steel, Hardened Steel, Cast Iron, and Titanium alloys—significantly faster, cooler, and with greater precision than standard High-Speed Steel (HSS) twist drills.
Unlike traditional drilling bits that grind the entire surface area of the hole, the Strovolt TCT Annular Cutter removes material only at the periphery, ejecting a solid 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, the STRO784350 offers superior thermal stability, allowing it to maintain a sharp cutting edge even under high-temperature drilling conditions where HSS bits would fail.
The cutting geometry of this annular core cutter features a sophisticated 3-ply design with outer, middle, and inner cutting edges. This multi-cut geometry balances chip load, reduces vibration, and prevents chatter, resulting in superior hole quality and extended tool life. Compared to standard HSS cutters, the Strovolt TCT Annular Cutter lasts up to 10 times longer when drilling hard, abrasive materials, delivering exceptional value and productivity.
With a precision-ground 19.05mm (3/4") Weldon Shank featuring two flats, the STRO784350 offers a universal fit, securely locking into almost all major magnetic drill brands, including Alfra, Hougen, Jancy, and Euroboor. The self-centering design ensures smooth starts without walking, eliminating the need for pre-drilling or center punching, saving time and effort on every job.
The Strovolt 43x50mm TCT Annular Cutter is a critical tool for fabrication shops, construction sites, and heavy industry maintenance. In structural steel fabrication, it rapidly creates 43mm 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 STRO784350 is also an essential tool for railway and transport maintenance, enabling efficient drilling for rail track repairs, chassis manufacturing, and heavy earthmoving equipment overhauls. In bridge and infrastructure projects, it is used for on-site drilling of rivet removals and structural reinforcements.
Engineered for superior performance and durability, the Strovolt TCT Annular Cutter features premium materials and construction. The cutting tips are made from Micro-Grain Tungsten Carbide (Sandvik or equivalent K-Grade) selected for maximum impact strength and heat resistance. The body is constructed from high-toughness Alloy Tool Steel, heat-treated to resist torsional stress and prevent snapping under heavy loads. The carbide tips are induction brazed using a high-strength silver alloy, ensuring they remain securely bonded even under extreme thermal shock. A polished finish with oil-preserving flutes assists with lubrication and chip evacuation.
With its advanced engineering, premium materials, and robust construction, the Strovolt STRO784350 TCT Annular Core Cutter delivers exceptional performance, durability, and value for demanding industrial drilling applications.
