05E312 - Walter SST Core Cut Annular Cutter 3/4 x 2 Inch Universal Shank

Precision Engineering for Heavy-Duty Drilling

The Walter 05E312 SST Core Cut Annular Cutter represents a significant advancement in hole-making technology for industrial fabrication. Designed with a 3/4-inch diameter and a 2-inch cutting depth, this tool is engineered to deliver exceptional performance across a variety of ferrous and non-ferrous metals. The defining feature of the SST (Super Speed Tip) series is its proprietary bronze surface treatment. This advanced coating is not merely aesthetic; it plays a critical role in tribology, significantly reducing the coefficient of friction between the tool and the workpiece. By minimizing friction, the cutter generates less heat during the drilling process, which is the primary cause of premature tool failure and work hardening in materials like stainless steel.

Structurally, the cutter features fully ground flutes that are generously sized to facilitate rapid chip evacuation. In deep hole drilling—such as the 2-inch depth provided by this model—efficient material removal is essential to prevent binding and breakage. The modern tooth geometry is optimized to slice through material with minimal resistance, requiring less feed pressure from the magnetic drilling unit. This results in a cleaner, burr-free hole that often eliminates the need for secondary reaming or deburring operations, thereby streamlining the production workflow.

The universal shank design further enhances the utility of the 05E312. It is compatible with the majority of magnetic drilling machines on the market, including those requiring Weldon or Nitto style shanks. This universality simplifies inventory management for shops that utilize multiple brands of drilling equipment. Whether working on structural steel erection, heavy machinery assembly, or custom fabrication, the Walter SST Core Cut provides the reliability and precision required for critical connections.

Operators will appreciate the consistency provided by the SST technology. The reduction in heat generation not only preserves the temper of the cutter but also protects the metallurgical integrity of the surrounding base material. This is particularly important in applications involving heat-sensitive alloys or where thermal distortion must be kept to an absolute minimum.
