Strovolt Premium TCT Annular Core Cutter 40mm Diameter x 50mm Depth Tungsten Carbide Tipped Mag Drill Bit Heavy Duty Metal Cutter
Product Overview
The Strovolt STRO784050 is a premium-quality Tungsten Carbide Tipped (TCT) Annular Core Cutter engineered for high-performance drilling in heavy industrial environments. With a robust 40mm cutting diameter and an extended 50mm cutting depth, this core drill bit is the ultimate solution for boring clean, precise holes in tough metals, including Stainless Steel, Cast Iron, Hardened Steel, and exotic alloys.
Unlike traditional twist drills that require massive horsepower and pre-drilling, the Strovolt TCT Series 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. Engineered with Advanced Micro-Grain Carbide Tips, the STRO784050 withstands higher temperatures and abrasion than High-Speed Steel (HSS), making it indispensable for production environments where tool life and speed are critical.
Featuring a specialized Triple-Edge Geometry, this TCT Annular Cutter splits the chip load across three distinct cutting edges (inner, middle, outer), reducing resistance and preventing chatter during the cut. The High Thermal Stability of the Micro-Grain Carbide Tips enables dry drilling in cast iron or high-speed drilling in steel without losing temper hardness. Equipped with a precision 19.05mm (3/4") Weldon Shank (2-flat), the STRO784050 ensures a secure fit in all major magnetic drill brands, including Alfra, Hougen, Evolution, and Nitto.
The Strovolt 40mm x 50mm TCT Cutter is a versatile workhorse for fabrication and heavy industry applications. In Structural Steel projects, it is essential for drilling 40mm clearance holes for large anchor bolts in I-beams, columns, and base plates. For Process Piping, it is ideal for creating tapping holes or inlets in thick-walled pipes, flanges, and pressure vessels. In Heavy Machinery Repair, it is used for re-boring pivot points and mounting holes on excavators, cranes, and mining equipment. For Hard Alloy Fabrication, it effortlessly cuts through Stainless Steel (INOX), Hardox, and high-tensile structural steel (St52). In Construction, it is perfect for bridge retrofitting and railway infrastructure projects requiring on-site drilling.
With a precision internal bore, the STRO784050 facilitates smooth slug ejection immediately after the cut is complete, delivering a reamer-quality finish (Ra 3.2) that often eliminates the need for deburring. Drills 3x faster than HSS annular cutters and 10x faster than twist drills, this TCT Cutter is compatible with internal cooling systems for maximum longevity.
Engineered with the highest quality materials, the STRO784050 features K-Grade Micro-Grain Tungsten Carbide tips (Sandvik equivalent), chosen for their optimal balance of hardness and toughness to resist impact fracture. The body is constructed from High-strength Heat-Treated Alloy Steel, engineered to absorb torsional vibration and prevent shank breakage. The carbide tips are secured with a Silver-alloy brazing process, ensuring they remain secure even under extreme heat and intermittent cutting stress.
