05A504 - Walter SST Corecut 2-1/4 Inch x 2 Inch Annular Cutter

Precision Engineering for Heavy-Duty Drilling

The Walter 05A504 SST Corecut Annular Cutter represents the pinnacle of hole-making technology for industrial fabrication. Designed with a 2-1/4 inch diameter and a 2-inch depth of cut, this tool is engineered to address the common challenges faced in metalworking: heat generation, chip evacuation, and tool longevity. At the heart of its performance is the revolutionary Super Speed Tip (SST) technology. This advanced surface treatment creates a bronze-colored finish that does more than just look professional—it actively eliminates microscopic porosity on the cutter's surface. By smoothing out these imperfections, the SST coating significantly reduces the coefficient of friction between the tool and the workpiece.

Reduced friction translates directly to reduced heat buildup, which is the primary enemy of cutting tool life, especially when working with work-hardening materials like stainless steel. The Walter SST Corecut maintains its hardness and cutting edge longer, ensuring consistent performance over hundreds of holes. Furthermore, the cutter features fully ground, extra-large flutes. This geometric optimization allows for the rapid and efficient evacuation of metal chips, preventing clogging and binding even during deep hole drilling operations. The result is a cleaner cut with superior surface finish, often eliminating the need for secondary reaming or deburring operations.

Universal Compatibility and Versatility

Industrial environments require tools that are versatile and adaptable. The 05A504 features a universal shank design, making it compatible with virtually all major brands of magnetic drilling units and stationary drill presses. Whether you are fabricating structural steel beams, processing aluminum plates, or drilling into tough stainless steel assemblies, this cutter delivers reliable precision. The modern tooth design is optimized to balance cutting forces, reducing vibration and chatter, which further protects the machine spindle and improves hole accuracy.

Key Technical Benefits

• Heat Management: The bronze SST treatment acts as a thermal barrier and lubricant retainer, keeping cutting temperatures in the optimal range.
• Structural Integrity: Manufactured from high-quality high-speed steel (HSS) and treated to resist wear in abrasive environments.
• Operational Efficiency: Faster penetration rates mean reduced cycle times per hole, increasing overall shop throughput.
