Strovolt 78mm x 50mm TCT Annular Core Cutter Industrial Tungsten Carbide Tipped Mag Drill Bit Heavy-Duty Hole Saw for Stainless Steel, Rail & Hardox STRO787850
Product Overview
The Strovolt STRO787850 is a professional-grade 78mm TCT (Tungsten Carbide Tipped) Annular Core Cutter designed for demanding metalworking applications. With a massive 50mm (2") cutting depth, this heavy-duty hole saw effortlessly penetrates thick structural beams, pressure vessels, and toughened alloys like stainless steel, railway steel, cast iron, and Hardox with surgical precision.
Engineered with a high-efficiency hollow-core design, the STRO787850 focuses all drilling energy on the periphery of the hole, resulting in faster penetration, lower torque requirements, and a mirror-like, burr-free finish that eliminates secondary deburring. The ultra-hard TCT tips, featuring a proprietary multi-angle grind, maintain structural integrity at temperatures exceeding 900°C, ensuring a long service life in abrasive materials.
The cutter's shock-resistant Chrome-Vanadium Alloy Steel body provides the flexibility to absorb vibrations from large-diameter drilling without fracturing the carbide teeth. The precision-ground 19.05mm (3/4") Weldon Shank ensures 100% compatibility with all industry-standard magnetic drill presses.
With its triple-edge tooth geometry, arranged in internal, middle, and external stages, the STRO787850 balances cutting force, eliminates chatter, and ensures a smooth breakthrough in thick plates. Deep, high-volume spiral flutes rapidly evacuate metal shavings, maintaining optimal cooling during full 50mm deep-hole cycles.
This versatile tool delivers high-tolerance holes with zero pre-drilling required, significantly reducing labor time on job sites. It's an essential choice for structural engineering, hardened metal fabrication, infrastructure maintenance, shipyard work, oil rig construction, and heavy machinery repair.
