Strovolt Premium TCT Annular Core Cutter | 30mm Diameter x 50mm Depth | Tungsten Carbide Tipped Mag Drill Bit | Part No: STRO783050

The Strovolt STRO783050 is a professional-grade 30mm TCT (Tungsten Carbide Tipped) Annular Cutter designed for extreme performance in heavy-metal fabrication. With a 50mm (2") cutting depth, this industrial-strength hole saw is engineered to penetrate the thickest structural steel, hardened alloys, and specialized materials where traditional HSS bits fail or burn out.

Featuring ultra-hard tungsten carbide inserts with a proprietary 3-stage grinding profile, the STRO783050 maintains its structural integrity at temperatures exceeding 900°C, ensuring a long service life in abrasive metals. The tension-tested Chrome-Vanadium Alloy Steel body offers superior vibration absorption to prevent brittle carbide tips from chipping under heavy torque loads.

The triple-edge tooth geometry balances the cutting force, eliminates chatter, and ensures a smooth, effortless breakthrough in thick plate. Optimized spiral flutes with high-volume fluting facilitate rapid chip evacuation, preventing slug jamming and heat buildup during deep 50mm penetration. With its precision-ground 19.05mm (3/4") Weldon Shank, the STRO783050 is 100% compatible with all industry-standard magnetic drill presses.

Capable of drilling up to 10 times more holes than standard HSS cutters in hardened materials, the STRO783050 significantly reduces the cost-per-hole, offering superior ROI for professional applications. This 30mm annular core cutter is essential for structural engineering projects, creating precision clearance holes for M27 bolts in bridge girders, refinery frames, and heavy infrastructure. It effortlessly drills through stainless steel, railway steel, cast iron, and high-tensile Hardox plates, making it indispensable for mining equipment repair, shipyard maintenance, and heavy-duty chassis manufacturing.
