Strovolt 35mm 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 STRO783550 is a heavy-duty 35mm TCT (Tungsten Carbide Tipped) Annular Core Cutter engineered for maximum performance in demanding metal fabrication applications. With a substantial 50mm (2") cutting depth, this industrial-grade tool is the definitive solution for operators who need to penetrate thick structural steel, stainless steel, and high-tensile alloys where standard HSS bits fail or burn out.
Utilizing a high-efficiency hollow-core design, the STRO783550 removes only the rim of the hole, leaving a solid steel slug. This drastically reduces the torque required from your magnetic drill press, allowing for faster feed rates and a reamer-quality, burr-free finish that is ready for immediate assembly. The ultra-hard TCT inserts, featuring a proprietary 3-stage grinding profile, maintain structural hardness at temperatures exceeding 900°C, making them ideal for drilling abrasive materials like railway steel and Hardox.
The cutter body is precision-machined from high-grade Chrome-Vanadium Alloy Steel, offering superior shock absorption to prevent the brittle carbide tips from chipping under the high torque of a 35mm bore. The universal 3/4" Weldon Shank ensures a secure, slip-free fit in all major magnetic drill brands. The triple-edge tooth geometry balances the cutting load across the tooth face, eliminates "chatter," and ensures a smooth, surgical breakthrough, while the high-volume spiral flutes are engineered for rapid chip evacuation, preventing "slug jamming" and thermal buildup during full 50mm deep penetration.
With the capability of drilling up to 10 times faster than a standard twist drill, the Strovolt STRO783550 significantly lowers the total labor cost-per-hole on industrial-scale projects. This 35mm diameter core cutter is an essential tool for structural engineering, precision clearance holes for M33 bolts in bridge girders, refinery frames, and heavy infrastructure, effortless drilling through hardened metals like Stainless Steel, Railway Steel, Cast Iron, and high-tensile Hardox plates, as well as mining equipment repair, shipyard maintenance, and heavy-duty chassis manufacturing.
