05A503 - Walter SST Core Cut Annular Cutter 2-3/16 Inch x 2 Inch Depth

High-Performance Drilling with Walter SST Core Cutters

The Walter 05A503 SST Core Cut Annular Cutter represents the pinnacle of hole-making technology for metal fabrication. Designed with a substantial 2-3/16" diameter and a 2" cutting depth, this tool is engineered to handle the most demanding structural steel and stainless steel applications. Unlike traditional twist drills that must remove all material from the hole, this core cutter only removes a narrow ring of material, significantly reducing the horsepower required and increasing drilling speed. This efficiency makes it an indispensable tool for operators using magnetic drilling units in the field or stationary machines in the shop.

At the heart of this cutter's performance is Walter's exclusive Super Speed Tip (SST) technology. The specialized bronze surface treatment is not merely a coating but a performance enhancer that drastically reduces friction at the cutting edge. This reduction in friction minimizes heat buildup—the primary enemy of cutting tool life—allowing the cutter to maintain its hardness and edge retention even during prolonged drilling sessions. The result is a tool that cuts faster, lasts longer, and produces a flawlessly smooth finish that often eliminates the need for secondary reaming or deburring operations.

Chip evacuation is critical in deep hole drilling, and the Walter 05A503 excels in this area. It features fully ground, oversized flutes that channel chips away from the work surface rapidly. This prevents chip clogging, which can lead to cutter breakage or poor surface finish. The modern tooth geometry is optimized to bite cleanly into materials ranging from aluminum to heavy structural steel, ensuring a stable and precise cut every time. Furthermore, the universal shank design ensures compatibility with virtually all major brands of magnetic drills, making this a versatile addition to any tool crib.

Whether you are working on bridge construction, heavy equipment repair, or general metal fabrication, the Walter SST Core Cut delivers reliability and precision. Its ability to eliminate porosity in the fabrication process ensures that every hole meets strict quality standards. Invest in the Walter 05A503 for a drilling solution that combines speed, durability, and exceptional finish quality.
