05E310 - Walter SST Core Cut Annular Cutter 5/8" x 2" Universal Shank

High-Performance Drilling with SST Technology

The Walter 05E310 SST Core Cutter represents a significant advancement in hole-making technology for industrial applications. Engineered with Walter's proprietary SST (Special Bronze) surface treatment, this 5/8-inch diameter cutter is designed to overcome the common thermal and mechanical challenges associated with drilling tough metals. The specialized coating effectively modifies the tribological properties of the tool surface, drastically reducing friction between the cutter and the workpiece. This reduction in friction not only minimizes heat generation—a primary cause of tool failure—but also prevents the adhesion of material to the cutting edges, ensuring consistent performance over a longer service life.

Beyond its surface treatment, the geometry of the SST Core Cutter is optimized for efficiency. It features fully ground, extra-large flutes that facilitate superior material evacuation. In deep hole drilling (up to 2 inches), effective chip removal is critical to prevent binding and breakage. The modern tooth design works in tandem with the flute geometry to slice through material with less resistance, requiring less power from the drilling unit. This makes it an excellent choice for both portable magnetic drills and stationary workshop machinery.

Versatility is a core component of this tool's design. The universal shank ensures compatibility with a wide array of magnetic drilling units, eliminating the need for specialized adapters in most setups. Whether working with mild steel, structural steel, or more difficult alloys like stainless steel and aluminum, the Walter SST Core Cutter delivers a porosity-free, burr-free finish that often eliminates the need for secondary reaming or deburring operations.
