05A401 - Walter SST Core Cutter 1-1/16 Inch x 2 Inch Depth Universal Shank

Advanced Metallurgy for Precision Drilling

The Walter 05A401 SST Core Cutter represents a significant leap forward in annular cutter technology, designed specifically for heavy-duty industrial applications where precision and tool longevity are paramount. This 1-1/16" diameter cutter with a 2" depth of cut utilizes Walter's proprietary Super Speed Tip (SST) technology. This advanced manufacturing process involves a specialized surface treatment that effectively eliminates microscopic porosity on the cutter's surface. The result is an exceptionally sleek, bronze-finished tool that minimizes friction at the cutting interface.

In industrial drilling operations, heat is the primary enemy of tool life. The SST Core Cutter addresses this by ensuring that the friction coefficient remains low throughout the drilling cycle. This reduction in heat generation not only preserves the temper of the cutting edge but also prevents work hardening of the base material, which is particularly critical when working with stainless steel and other tough alloys. The cutter features fully ground, oversized flutes that are geometrically optimized to evacuate chips rapidly, preventing clogging and further reducing thermal stress on the tool.

Compatibility and versatility are engineered into the design via a universal shank, making this cutter compatible with a wide array of magnetic drilling units and stationary production machinery. Whether fabricating structural steel components or performing maintenance on heavy equipment, the 05A401 delivers consistent, burr-free holes with tight tolerances. The robust tooth design withstands the rigors of high-torque drilling, ensuring that operators can maintain peak productivity with fewer tool changes and reduced downtime.
