Strovolt Premium TCT Annular Core Cutter 38mm Diameter x 50mm Depth Tungsten Carbide Tipped Mag Drill Bit Hardened Steel & Inox Ready
Product Overview
The Strovolt STRO783850 is a heavy-duty 38mm diameter x 50mm depth Tungsten Carbide Tipped (TCT) Annular Core Cutter engineered for extreme industrial drilling applications. This professional-grade core drill bit is designed to bore through the toughest materials like Stainless Steel, Hardened Steel, Cast Iron, and Titanium alloys with superior speed, precision, and efficiency compared to standard High-Speed Steel (HSS) twist drills.
Unlike traditional drill bits that grind the entire hole surface, the Strovolt TCT Annular Cutter removes material only at the periphery, ejecting a solid slug at the end of the cut. This innovative cutting action 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 STRO783850 maintains a sharp cutting edge even under extreme heat and abrasion where HSS bits would fail.
With a sophisticated 3-Ply Cutting Geometry utilizing outer, middle, and inner cutting edges, this annular cutter balances chip load, reduces vibration, and prevents chatter for ultra-smooth hole finishes (Ra 3.2 or better) in a single pass. The precision-ground 19.05mm (3/4") Weldon Shank with dual flats ensures a secure fit in almost all major magnetic drill brands like Alfra, Hougen, Jancy, and Euroboor. The self-centering design starts cuts smoothly without walking, eliminating the need for pre-drilling or center punching.
Engineered for extended tool life up to 10 times longer than HSS cutters on hard, abrasive materials, the Strovolt 38x50mm TCT Annular Core Cutter is a critical tool for fabrication shops, construction sites, and heavy industry maintenance. It excels at rapidly creating clean, burr-free 38mm holes for heavy-duty bolts, anchors, and threaded rods in structural steel like I-beams, H-beams, and girders. It's also ideal for drilling thick-walled pipes, boiler tanks, heat exchangers, and hard-to-machine materials like Stainless Steel (INOX), Hardox (Wear Plate), and high-tensile structural steel used in pipe/pressure vessel manufacturing, railway maintenance, chassis fabrication, bridge infrastructure, and repairing heavy earthmoving equipment.
The high-performance Strovolt TCT Annular Cutter features a high-toughness Alloy Tool Steel body heat-treated to resist torsional stress and prevent snapping under heavy loads. The premium Micro-Grain Tungsten Carbide tips (Sandvik or equivalent K-Grade) are selected for maximum impact strength and heat resistance, then induction brazed using a high-strength silver alloy to ensure a secure bond that withstands extreme thermal shock. With an optimized internal taper for reliable slug ejection and polished flutes with an oil-preserving coating to assist lubrication and chip evacuation, the STRO783850 delivers industrial-grade cutting power, durability, and precision unmatched by conventional drilling tools.
