Strovolt 45mm x 50mm TCT Annular Core Cutter Industrial Tungsten Carbide Tipped Mag Drill Bit Heavy-Duty Hole Saw for Stainless Steel, Rail & Hardox

The Strovolt 45mm x 50mm TCT Annular Core Cutter (STRO784550) is a heavy-duty hole saw engineered for demanding industrial applications. Built with premium Tungsten Carbide Tipped (TCT) inserts, this cutter effortlessly drills through thick structural steel, stainless steel, railway steel, Hardox, and other high-tensile alloys where standard HSS bits fail or burn out.

Featuring a high-efficiency hollow-core design, the STRO784550 removes only the rim of the hole, leaving a solid steel slug and drastically reducing the torque required from your magnetic drill press. This allows for faster feed rates and a reamer-quality, burr-free finish ready for immediate assembly in critical structural joints.

The ultra-hard TCT inserts maintain structural hardness at temperatures exceeding 900°C, while the tension-tested Chrome-Vanadium Alloy Steel body offers superior shock absorption to prevent carbide chipping under massive torque. The triple-edge tooth geometry balances the cutting load, eliminates chatter, and ensures a smooth, surgical breakthrough even in work-hardened metals.

With a substantial 50mm (2") cutting depth and wide spiral flutes for rapid chip evacuation, this annular cutter is capable of drilling up to 10x faster than a standard twist drill, significantly lowering the total labor cost-per-hole on industrial-scale projects. The universal 3/4" Weldon Shank ensures a secure, slip-free fit in all major magnetic drill brands.

Ideal for structural engineering, shipyard maintenance, oil rig fabrication, wind turbine base assembly, and other heavy metal fabrication applications, the Strovolt 45mm TCT Annular Core Cutter is the definitive solution for operators who demand uncompromising performance and efficiency.
