Strovolt 84mm x 50mm TCT Annular Core Cutter Industrial Tungsten Carbide Tipped Mag Drill Bit Heavy-Duty Hole Saw for Stainless Steel, Rail & Hardox STRO788450

The Strovolt STRO788450 is a professional-grade 84mm x 50mm TCT (Tungsten Carbide Tipped) Annular Core Cutter, engineered for maximum efficiency in demanding metalworking applications. This heavy-duty hole saw is the ultimate solution for fabricators who need to penetrate thick structural beams, pressure vessels, and toughened alloys with surgical precision.

Utilizing a high-efficiency hollow-core design, the STRO788450 removes only the periphery of the hole, drastically reducing the energy required from your magnetic drill press. This results in faster penetration, lower vibration, and a mirror-like finish that eliminates the need for secondary reaming, even in high-tensile materials like stainless steel, railway steel, or Hardox.

The cutter features ultra-hard TCT tips with a proprietary multi-angle grind, maintaining structural integrity at temperatures exceeding 900°C for a long service life in abrasive and heat-sensitive materials. The shock-resistant alloy steel body provides the flexibility to absorb massive vibrations without fracturing the carbide teeth.

With a precision-ground 19.05mm (3/4") Weldon Shank, the STRO788450 ensures 100% compatibility with all industry-standard magnetic drill presses capable of driving large-bore cutters. The triple-edge tooth geometry balances the cutting load, eliminates chatter, and ensures a smooth breakthrough in thick plates.

Engineered with extra-wide, high-volume spiral flutes, the cutter rapidly evacuates metal shavings, preventing slug jamming and overheating during an 84mm diameter bore. Capable of drilling up to 10x faster than a standard twist drill, the STRO788450 significantly lowers the total labor cost-per-hole on industrial infrastructure projects.
