Product Description

The Stainless steel 28mm hole opener is engineered for precision drilling in heavy-duty industrial applications, featuring a corrosion-resistant 28mm diameter design optimized for stainless steel and alloy materials. Compatible with standard rotary tools, it operates at 800-1200 RPM with a recommended input voltage range of 18-24V DC, suitable for workshop or onsite use. Its compact build supports seamless integration with modular drilling systems, while heat-treated carbide teeth ensure extended durability across -20°C to 80°C environments. Ideal for metal fabrication, pipeline installation, and machinery maintenance, this 28mm special hole opener delivers superior concentricity within 0.05mm tolerance. Key advantages include reduced burr formation and single-pass drilling capability, though optimal performance requires periodic lubrication. The tool's 14mm shank diameter guarantees compatibility with most industrial-grade chucks.
