05E403 - Walter SST Core Cut Annular Cutter 1-3/16" x 2" Universal Shank

Precision Engineering for Industrial Drilling

The Walter 05E403 SST Core Cut Annular Cutter represents the pinnacle of hole-making technology for industrial applications. Designed with a diameter of 1-3/16 inches and a cutting depth of 2 inches, this tool is engineered to deliver exceptional performance in the most demanding environments. At the heart of its design is the Super Speed Tip (SST) technology, a specialized bronze surface treatment that fundamentally changes the interaction between the tool and the workpiece. By significantly reducing the coefficient of friction, the SST coating minimizes heat generation—the primary enemy of cutting tool longevity. This allows for sustained high-speed drilling without the rapid degradation often seen in standard high-speed steel cutters.

Beyond its advanced coating, the physical geometry of the cutter is optimized for efficiency. The tool features fully ground, extra-large flutes that provide a clear path for chip evacuation. In deep hole drilling, chip packing can lead to increased pressure, heat, and eventual tool breakage. Walter’s design ensures that material is ejected smoothly, maintaining a cool cutting interface and reducing the load on the drilling machine. The modern tooth design further enhances this by breaking chips into manageable sizes, ensuring a consistent and aggressive cut throughout the tool's life.

Versatility is a key component of the 05E403. The universal shank design allows this cutter to be utilized with a vast array of magnetic drilling units and stationary machines, making it a flexible addition to any machine shop or fabrication floor. Whether working with mild steel, high-tensile structural steel, or difficult-to-machine stainless steel and aluminum, the Walter SST Core Cut delivers a surface finish that is virtually free of porosity and burrs. This precision reduces the need for secondary finishing operations, streamlining production workflows and reducing overall operational costs. For professionals seeking a reliable, high-performance solution for large diameter hole creation, this annular cutter offers the durability and speed required to keep projects on schedule.
