Product Description

The 21mm stainless steel hole opener is a precision tool designed for creating clean, accurate 21mm diameter openings in stainless steel surfaces. Featuring a high-grade stainless steel construction with hardened cutting edges, this specialized hole opener 21mm operates at a recommended torque range of 10-30 Nm and tolerates ambient temperatures from -20°C to 80°C. Compatible with standard rotary tools via 1/4" hex shank, it requires a 12-24V power supply and suits applications in industrial fabrication, HVAC systems, and plumbing installations. The stainless steel hole cutter 21mm excels in durability and corrosion resistance, though its fixed diameter limits versatility. Its compact design ensures minimal material waste while maintaining cutting precision under high-stress conditions.
