Product Description

The Stainless Steel Hole Opener 70mm is a corrosion-resistant hole widener engineered for precision in demanding industrial environments. This 70mm heavy-duty hole expander operates without external power inputs, directly integrating with standard rotary drilling systems via a universal thread interface. Constructed from marine-grade stainless steel, it excels in corrosive settings like offshore, chemical processing, and food production, withstanding temperatures from -30°C to 250°C. The tool enables clean hole expansion up to 70mm diameter with ±0.2mm tolerance, featuring a tapered carbide cutting head for reduced friction. Advantages include extended service life, no lubrication requirements, and compatibility with automated CNC rigs. While optimized for stainless steel and alloy substrates, its non-adjustable cutting profile limits multi-material versatility. The compact 85mm body length ensures maneuverability in confined spaces.
