Strovolt Premium TCT Annular Core Cutter 50mm Diameter x 50mm Depth Tungsten Carbide Tipped Mag Drill Bit Heavy Duty Structural Steel Cutter
Product Overview
The Strovolt STRO785050 is a professional-grade 50mm Tungsten Carbide Tipped (TCT) Annular Core Cutter engineered for high-performance drilling in heavy industrial environments. This heavy-duty structural steel cutter features a substantial 50mm cutting diameter and an extended 50mm cutting depth, making it the ultimate solution for boring clean, large-diameter holes in tough metals like Stainless Steel, Cast Iron, Hardened Steel, and exotic alloys.
Unlike traditional twist drills that require massive horsepower and heavy feed pressure, the Strovolt TCT Annular Cutter revolutionizes the drilling process by cutting only the periphery of the hole and ejecting a solid slug. This innovative geometry significantly reduces energy consumption, minimizes wear on your magnetic drill, and delivers a burr-free finish in seconds, improving efficiency and productivity in production environments where tool life and speed are critical.
Engineered with Advanced Micro-Grain Carbide Tips from Sandvik, the STRO785050 withstands higher temperatures and abrasion than High-Speed Steel (HSS) cutters, making it indispensable for dry drilling in cast iron or high-speed drilling in steel without losing temper hardness. The specialized Triple-Edge Geometry features a 3-ply tooth design (inner, middle, outer) that splits the chip load, reducing cutting resistance and preventing chatter, which is crucial when drilling larger diameters like 50mm.
The precision 19.05mm (3/4") Weldon Shank ensures a secure fit in all major magnetic drill brands, including Alfra, Hougen, Evolution, Nitto, and Euroboor, while the internal bore facilitates smooth slug ejection immediately after the cut is complete. Constructed with a high-strength Heat-Treated Alloy Steel body and Silver-alloy brazed Carbide tips, the STRO785050 is engineered to absorb torsional vibration, prevent shank breakage, and withstand extreme heat and intermittent cutting stress.
This versatile 50mm x 50mm TCT Annular Cutter is a workhorse for fabrication and heavy industry applications, including structural steel drilling for clearance holes in I-beams, columns, and base plates; process piping for tapping holes or inlets in thick-walled pipes, flanges, and pressure vessels; heavy machinery repair for re-boring pivot points and mounting holes on excavators, cranes, and mining equipment; hard alloy fabrication of Stainless Steel (INOX), Hardox, and high-tensile structural steel (St52); and construction projects like bridge retrofitting and railway infrastructure.
With a cutting speed up to 3 times faster than HSS annular cutters and 10 times faster than twist drills, the Strovolt STRO785050 delivers a reamer-quality finish (Ra 3.2), often eliminating the need for deburring. Compatible with internal cooling systems for maximum longevity, this premium TCT Annular Core Cutter combines superior cutting performance, extended tool life, and exceptional hole quality, making it an essential tool for metalworking professionals across various industrial sectors.
