05A311 - Walter SST Core Cut 11/16" x 2" Annular Cutter with Universal Shank

High-Performance Drilling with Walter SST Core Cut Technology

The Walter 05A311 SST Core Cut Annular Cutter represents the pinnacle of hole-making technology for industrial fabrication. Designed with a diameter of 11/16 inches and a cutting depth of 2 inches, this tool is engineered to deliver precision, speed, and durability in the most demanding environments. At the heart of its performance is Walter's exclusive SST (Super Speed Treatment) surface technology. This specialized bronze treatment significantly reduces surface porosity, creating an exceptionally smooth exterior that minimizes friction during operation. By reducing friction, the cutter generates less heat, which is the primary enemy of cutting tool longevity, thereby extending the life of the bit even when drilling through tough materials like stainless steel and structural alloys.

Efficiency in material evacuation is critical for deep hole drilling, and the SST Core Cut excels in this area. It features fully ground, extra-large flutes that rapidly channel chips away from the cutting zone. This design prevents chip packing and heat buildup, ensuring a continuous, smooth cutting action. The modern tooth geometry is optimized to bite cleanly into the workpiece, requiring less feed pressure from the operator and reducing wear on the magnetic drilling unit. Whether you are working with aluminum, mild steel, or hardened structural components, this cutter delivers a burr-free, reamer-quality finish that often eliminates the need for secondary deburring operations.

Versatility is a key component of the Walter 05A311 design. It is equipped with a universal shank, making it compatible with virtually all major brands of magnetic drilling units and stationary drill presses. This universality simplifies inventory management for shops that utilize multiple machine brands. The cutter is robust enough to handle the rigors of heavy manufacturing while precise enough for delicate fabrication tasks. By choosing the Walter SST Core Cut, operators gain the advantage of faster drilling cycles, fewer tool changes, and consistently accurate hole dimensions, ultimately driving down the cost per hole in production settings.

In summary, the Walter 11/16" x 2" SST Core Cut is more than just a drill bit; it is a productivity solution. Its combination of advanced materials, smart geometry, and surface treatment technology makes it an indispensable tool for metalworkers seeking reliability and performance. Invest in Walter's proven quality to enhance your machining capabilities and achieve flawless results in every application.
