Drill Annular Cutter Set | 7pcs HSS Core Bits 12-22mm | For Stainless Steel & Metal

The XCAN 7pc HSS Core Drill Bit Set is designed for high-efficiency metal drilling, creating large-diameter holes with minimal effort. These annular cutters remove only a ring of material, requiring significantly less power than conventional twist drills and producing clean, burr-minimized holes in thick stock. Features and Benefits - Annular Cutter (Hollow Drill) Design - Removes a core of material, drastically reducing cutting force and heat generation for faster, cooler drilling. - Weldon Shank Compatibility - Ensures a secure, vibration-free fit in magnetic drill presses and compatible rotary tools for stable, accurate operation. - High-Speed Steel Construction - Delivers the toughness and wear resistance needed for continuous drilling in stainless steel and other tough metals. - Practical 12-22mm Size Range - Covers essential large-diameter hole requirements for plumbing, electrical, and structural applications. Applications - Creating clean, large-diameter holes in structural steel, I-beams, and metal plate with a magnetic drill press. - Installation of pipes, conduits, and hardware in stainless steel fabrication. - Industrial construction and shipbuilding where precision and speed in thick metal are paramount.
