Strovolt Premium TCT Annular Core Cutter 56mm Diameter x 50mm Depth Tungsten Carbide Tipped Mag Drill Bit Heavy Duty Structural Steel & Inox Cutter
Product Overview
The Strovolt STRO785650 is a heavy-duty TCT (Tungsten Carbide Tipped) Annular Core Cutter designed for demanding industrial applications. With a massive 56mm cutting diameter and an extended 50mm cutting depth, this professional core drill bit effortlessly bores precise, large-diameter holes through the toughest materials, including structural steel, stainless steel, cast iron, and hardened alloys.
Engineered for extreme performance, the STRO785650 features a sophisticated triple-edge ply geometry that utilizes inner, middle, and outer cutting edges to evenly distribute chip load. This advanced design reduces cutting resistance, prevents chatter, and ensures smooth penetration, even in thick, challenging workpieces. The self-centering geometry eliminates the need for center punching or pilot drilling, allowing immediate cutting without "walking" across the surface.
Constructed with premium K-Grade micro-grain tungsten carbide tips from renowned manufacturers like Sandvik, the STRO785650 offers exceptional hardness (HRC 90+) and impact toughness to resist chipping and premature wear. The carbide tips are securely bonded to a heat-treated alloy steel body using state-of-the-art induction brazing with a high-strength silver alloy, ensuring they remain firmly attached even under extreme thermal shock and vibration.
The STRO785650 is compatible with all major magnetic drill brands, thanks to its precision-ground 19.05mm (3/4") Weldon shank (2-flat) that ensures a rigid, slip-free connection. Its high-speed performance capabilities allow for higher surface speeds (RPM) compared to conventional High-Speed Steel (HSS) cutters, significantly reducing cycle times and boosting production output.
This heavy-duty TCT annular cutter is an essential tool for various industries, including structural steel fabrication, oil and gas pipeline work, heavy equipment repair, hard alloy machining, and power generation. In structural steel fabrication, it creates 56mm holes for large-diameter anchor bolts and tie-rods in heavy I-beams, H-beams, and bridge girders. For pipeline and flange work, it is ideal for drilling bolt patterns in high-pressure flanges and thick-walled pipe vessels in refineries.
In the heavy equipment repair sector, the STRO785650 is used for line-boring pivot points and mounting holes on mining excavators, cranes, earthmovers, and railway chassis. Its ability to effortlessly cut through difficult materials like stainless steel (INOX), Hardox (wear plate), and railway track makes it indispensable for hard alloy machining tasks. Additionally, it plays a crucial role in the fabrication of wind turbine towers and hydroelectric plant components in the power generation industry.
With its advanced cutting geometry, premium tungsten carbide tips, and robust alloy steel construction, the Strovolt STRO785650 TCT Annular Core Cutter delivers exceptional performance, durability, and efficiency. Its ability to produce a mirror-like, burr-free finish (Ra 3.2 or better) eliminates the need for secondary grinding or reaming, further streamlining the workflow. Compatible with internal cooling systems (via pilot pin) to flush chips and extend tool life, this core cutter is a game-changer for heavy fabrication environments demanding uncompromising quality and productivity.
