Strovolt 66mm x 50mm TCT Annular Core Cutter Industrial Tungsten Carbide Tipped Mag Drill Bit Heavy-Duty Hole Saw for Stainless Steel, Rail & Hardox STRO786650
Product Overview
The Strovolt STRO786650 is a professional-grade 66mm TCT (Tungsten Carbide Tipped) Annular Core Cutter, engineered for peak performance in the most demanding metalworking applications. Featuring a massive 50mm (2") cutting depth, this heavy-duty hole saw is the ultimate solution for fabricators who need to penetrate thick structural beams, pressure vessels, and toughened alloys with surgical precision.
Utilizing a high-efficiency hollow-core design, the STRO786650 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 the need for secondary deburring or reaming – even in high-tensile materials like stainless steel, railway steel, cast iron, and Hardox.
This industrial-grade cutter boasts ultra-hard TCT tips with a proprietary multi-angle grind, maintaining structural integrity at temperatures exceeding 900°C for a long service life in abrasive materials. The shock-resistant alloy steel body provides the flexibility to absorb vibrations during large-diameter drilling without fracturing the carbide teeth.
With a precision-ground 19.05mm (3/4") Weldon Shank, the STRO786650 ensures 100% compatibility with all industry-standard magnetic drill presses. Its triple-edge tooth geometry balances cutting force, eliminates chatter, and ensures a smooth breakthrough in thick plate, while deep, high-volume spiral flutes rapidly evacuate metal shavings for efficient cooling during full 50mm deep-hole cycles.
Whether you're tackling structural engineering projects, heavy-duty anchoring in bridge girders, refinery frames, or stadium construction, or effortlessly drilling through hardened metals like stainless steel, railway steel, cast iron, and Hardox plates, the Strovolt STRO786650 delivers high-tolerance holes with zero pre-drilling or step-drilling required, significantly reducing labor time on the job site.
