05A201 - Walter SST Core Cut Annular Cutter 2-1/16 Inch x 1 Inch Depth

High-Performance Drilling with Walter SST Core Cut Technology

The Walter 05A201 SST Core Cut Annular Cutter represents the pinnacle of hole-making technology for industrial fabrication. Designed with a diameter of 2-1/16 inches and a cutting depth of 1 inch, this tool is engineered to deliver precision and speed in the most demanding environments. At the heart of its performance is Walter's exclusive SST (Super Surface Treatment), a specialized bronze finish that fundamentally changes how the cutter interacts with the workpiece. By eliminating microscopic surface porosity, the SST coating creates an exceptionally smooth surface that drastically reduces friction. Less friction means less heat generation, which is the primary enemy of cutting tool life.

Fabricators and machinists will appreciate the thoughtful geometry of the SST Core Cut. The cutter features fully ground, extra-large flutes that serve a critical function: rapid chip evacuation. In deep hole drilling, chip clogging can lead to tool breakage and poor surface finish. The deep flute design ensures that swarf is ejected efficiently, allowing the cutter to maintain high feed rates without binding. This makes it an ideal choice for drilling through tough materials like stainless steel, structural steel, and even aluminum, where chip welding can often be a problem.

Versatility is also a key component of the 05A201's design. It comes equipped with a universal shank, making it compatible with virtually all major brands of magnetic drilling units on the market today. Whether you are working in a fabrication shop or on a remote job site, this cutter integrates seamlessly into your existing workflow. The modern tooth design and cutter geometry further enhance its capability, providing clean, burr-free holes that often require no secondary finishing operations. For professionals seeking to reduce drilling time while maximizing tool longevity, the Walter SST Core Cut is the definitive solution.
