Strovolt Premium TCT Annular Core Cutter 59mm Diameter x 50mm Depth Tungsten Carbide Tipped Mag Drill Bit Heavy Duty Structural Steel & Inox Cutter
Product Overview
The Strovolt STRO785950 is a heavy-duty industrial TCT (Tungsten Carbide Tipped) Annular Core Cutter engineered for extreme performance in demanding fabrication environments. Featuring a massive 59mm cutting diameter and an extended 50mm cutting depth, this professional core drill bit is designed to bore large, precise holes in the toughest industrial metals, including Stainless Steel, Cast Iron, Hardened Steel, and High-Tensile Structural Steel, significantly faster and more efficiently than traditional twist drills.
Conventional methods of creating a 59mm hole typically require a massive radial arm drill, multiple step-drilling processes, and excessive horsepower. The Strovolt TCT Series revolutionizes this workflow by cutting only the periphery of the hole and ejecting a solid slug. This advanced geometry reduces power consumption by up to 60%, minimizes wear on your magnetic drilling machine, and delivers a burr-free, reamer-quality finish in a single pass. Featuring Advanced Micro-Grain Carbide Tips, the STRO785950 offers exceptional thermal stability, maintaining its cutting edge even under the high heat generated by large-diameter drilling.
The STRO785950 boasts a Triple-Edge Ply Geometry that utilizes a sophisticated 3-ply tooth arrangement (inner, middle, and outer cutting edges) to evenly distribute chip load. This design reduces cutting resistance, prevents chatter, and ensures smooth penetration in large 59mm bores. The precision-ground 19.05mm (3/4") Weldon Shank (2-flat) ensures a rigid, slip-free connection with all major magnetic drill brands, including Alfra, Hougen, Evolution, Nitto, Euroboor, and Rotabroach.
Additionally, the TCT Annular Cutter is capable of running at higher surface speeds (RPM) than High-Speed Steel (HSS) cutters, reducing cycle times and boosting production output. Its self-centering design starts cuts immediately without "walking," eliminating the need for center punching or pilot drilling.
The Strovolt 59mm x 50mm TCT Cutter is a critical tool for various heavy industry, construction, and maintenance sectors:
- Structural Steel Fabrication: Essential for creating 59mm holes for large-diameter anchor bolts and tie-rods in heavy I-beams, H-beams, and bridge girders.
- Pipeline & Flange Work: Ideal for drilling bolt patterns in high-pressure flanges and thick-walled pipe vessels in Oil & Gas refineries.
- Heavy Equipment Repair: Used for line-boring pivot points and mounting holes on mining excavators, cranes, earthmovers, and railway chassis.
- Hard Alloy Machining: Effortlessly cuts through difficult materials like Stainless Steel (INOX), Hardox (Wear Plate), and Railway Track.
- Power Generation: Used in the fabrication of wind turbine towers and hydroelectric plant components.
The STRO785950 is constructed with premium materials and advanced manufacturing techniques. The cutting tips are made of K-Grade Micro-Grain Tungsten Carbide (Sandvik or equivalent), selected for their optimal balance of extreme hardness and impact toughness to resist chipping. The high-strength Heat-Treated Alloy Tool Steel body is engineered to absorb high torsional stress and prevent shank breakage under heavy load. State-of-the-art induction brazing using a high-strength silver alloy ensures the carbide tips remain secure even under extreme thermal shock and vibration. The polished alloy finish with specialized flute geometry assists in rapid chip evacuation.
With its exceptional performance, robust construction, and versatility across various industrial applications, the Strovolt STRO785950 Premium TCT Annular Core Cutter is a must-have tool for any heavy fabrication or maintenance operation demanding fast, precise, and efficient large-diameter hole cutting in the toughest materials.
