Strovolt 85mm x 50mm TCT Annular Core Cutter Industrial Tungsten Carbide Tipped Mag Drill Bit Heavy-Duty Hole Saw for Stainless Steel, Rail & Hardox
Product Overview
The Strovolt 85mm x 50mm TCT Annular Core Cutter (STRO788550) is a heavy-duty, industrial-grade hole saw engineered for effortless drilling through thick structural steel, stainless steel, and high-tensile alloys like Hardox. Equipped with ultra-hard Tungsten Carbide Tipped (TCT) inserts that maintain hardness at temperatures exceeding 900°C, this cutter outperforms standard HSS bits in demanding metal fabrication applications.
The cutter's advanced triple-edge tooth geometry, with internal, middle, and external stages, balances the massive cutting load, eliminates chatter, and ensures a smooth breakthrough in thick plates. The forged Chrome-Vanadium alloy steel body provides the ideal balance of rigidity and impact absorption, protecting the carbide tips from micro-fractures during high-torque operations.
With a substantial 50mm (2") cutting depth and a 3/4" Weldon shank for secure fitment in magnetic drill presses, the STRO788550 is capable of drilling up to 10 times faster than standard twist drills. Its extra-wide, high-volume spiral flutes rapidly evacuate metal shavings, preventing slug jamming during 85mm diameter penetration, essential for time-sensitive industrial projects.
This versatile core cutter is a critical tool for structural engineering, precision clearance holes in bridge girders, refinery frames, and stadium construction. It effortlessly drills through hardened metals like stainless steel, railway steel, cast iron, and Hardox plates, making it indispensable for shipyard maintenance, oil rig fabrication, and wind turbine base assembly.
