Strovolt 18mm x 50mm TCT Annular Core Cutter Professional Tungsten Carbide Tipped Mag Drill Bit Heavy Duty Hole Saw for Stainless Steel & Structural Steel STRO781850
Product Overview
The Strovolt STRO781850 is an 18mm x 50mm TCT (Tungsten Carbide Tipped) Annular Core Cutter, engineered for extreme durability and precision in demanding industrial applications. Designed for professionals who demand the fastest hole-making solution, this cutter excels where standard HSS bits fail.
With a 50mm cutting depth, it is built to penetrate thick-walled materials, stacked plates, and hardened alloys with ease. The "core cutting" design ensures that energy is focused solely on the cutting edge, resulting in a 3x faster drilling speed and a perfectly clean, burr-free finish every time.
This annular core cutter features a combination of industrial-grade tungsten carbide tips that maintain their edge at temperatures exceeding 1000°C and a high-alloy steel body that provides the structural flexibility needed to handle high-torque drilling without fracturing. The precision-ground 19.05mm (3/4") Weldon Shank ensures a universal fit for nearly all magnetic drill brands.
The three-tier cutting system, with internal, middle, and external cutting edges, balances the load, prevents wandering, and significantly reduces the risk of tooth breakage. The mirror-finish internal wall ensures the "slug" is ejected effortlessly via the pilot pin, while the low thrust requirement extends the lifespan of your magnetic drill press motor.
Ideal for steel fabrication, transportation, marine, bridge, and infrastructure applications, the Strovolt STRO781850 18mm TCT Annular Core Cutter is the industry-standard solution for precise clearance holes in structural I-beams, columns, high-tensile stainless steel, railway tracks, ship hull plating, and hardened steel surfaces.
