Strovolt Premium TCT Annular Core Cutter 37mm Diameter x 50mm Depth Tungsten Carbide Tipped Mag Drill Bit Hardened Steel & Inox Ready
Product Overview
The Strovolt STRO783750 is a premium Tungsten Carbide Tipped (TCT) Annular Core Cutter engineered for extreme heavy-duty drilling applications in the toughest industrial materials. With a precise 37mm 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 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 from renowned manufacturers like Sandvik, the STRO783750 offers superior thermal stability, allowing it to maintain a sharp cutting edge even under high-temperature conditions where HSS bits would fail.
The cutting geometry of this annular cutter is engineered for maximum performance, utilizing a sophisticated 3-ply multi-cut design with outer, middle, and inner cutting edges. This balanced chip load geometry reduces vibration and prevents chatter, resulting in smoother, more accurate holes. With a precision-ground 19.05mm (3/4") Weldon Shank and two flats, the STRO783750 fits securely in almost all major magnetic drill brands, including Alfra, Hougen, Jancy, and Euroboor.
One of the key advantages of the Strovolt TCT Annular Cutter is its extended tool life. Compared to standard HSS cutters, this carbide-tipped core drill bit lasts up to 10 times longer when drilling hard, abrasive materials, significantly reducing downtime and replacement costs. Additionally, the self-centering design ensures smooth, accurate starts without walking, eliminating the need for pre-drilling or center punching.
The Strovolt 37x50mm TCT Cutter is a critical 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 steel fabrication shops, it rapidly creates 37mm holes for heavy-duty bolts, anchors, and threaded rods in I-beams, H-beams, and girders. For pipe and vessel manufacturers, it is ideal for drilling clean, burr-free holes in thick-walled pipes, boiler tanks, and heat exchangers. In the machining industry, it effortlessly cuts through difficult-to-machine materials like stainless steel (INOX), Hardox wear plate, and high-tensile structural steel.
Constructed with meticulous attention to quality, the STRO783750 features a high-toughness alloy tool steel body that is heat-treated to resist torsional stress and prevent snapping under heavy loads. The Tungsten Carbide tips, rated for HRC 90+ hardness, 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 STRO783750 Premium TCT Annular Core Cutter is an indispensable tool for fabricators, machinists, and maintenance professionals working in demanding industrial environments. Its ability to produce reamer-quality, smooth finishes (Ra 3.2 or better) in a single pass, while operating at significantly higher surface speeds than HSS, reduces cycle times by up to 40%, boosting productivity and efficiency.
