Strovolt 28mm x 50mm TCT Annular Core Cutter Industrial Tungsten Carbide Tipped Mag Drill Bit Heavy-Duty Hole Saw for Stainless Steel, Rail & Hardox STRO782850
Product Overview
The Strovolt STRO782850 is a professional-grade 28mm TCT (Tungsten Carbide Tipped) Annular Core Cutter engineered for maximum metal removal rates in demanding industrial applications. With a 50mm (2") cutting depth, this heavy-duty hole saw is the ultimate choice for fabricators working with thick structural steel, high-tensile alloys, and abrasive materials that quickly dull standard HSS bits.
Utilizing a high-efficiency hollow-core design, the STRO782850 focuses all drilling energy on the periphery, resulting in faster penetration, lower torque requirements, and a mirror-like, burr-free finish for immediate bolt installation without secondary reaming. The ultra-hard carbide inserts feature a proprietary multi-angle grind, maintaining structural hardness at temperatures exceeding 900°C for exceptional service life in hardened materials.
The shock-resistant Chrome-Vanadium Alloy Steel body provides the flexibility to absorb vibrations from heavy-duty drilling without fracturing the teeth. The precision-ground 19.05mm (3/4") Weldon Shank ensures a secure, slip-free fit in all major magnetic drill brands.
With a triple-edge cutting system balancing the load across the tooth face, deep spiral flutes for rapid chip evacuation, and a precision-tapered interior wall for instant slug ejection, this annular cutter delivers unparalleled performance. Ideal for structural engineering, hardened metals like Stainless Steel, Railway Steel, Cast Iron, and Hardox plates, as well as heavy infrastructure projects in shipbuilding, oil rigs, and machinery repair.
