05A202 - Walter SST Core Cut Annular Cutter 2-1/8 Inch x 1 Inch Depth

High-Performance Drilling with Walter SST Core Cut Technology

The Walter SST Core Cut Annular Cutter (SKU: 05A202) represents the pinnacle of drilling efficiency for industrial applications. Engineered for professionals who demand precision and speed, this 2-1/8" diameter cutter features a 1" depth of cut, making it a versatile tool for heavy-duty fabrication and maintenance tasks. The defining feature of this series is the exclusive SST (Super Surface Treatment), a specialized bronze finish that significantly alters the performance characteristics of the high-speed steel body.

Standard annular cutters often suffer from microscopic surface porosity, which creates friction points that generate excess heat and trap material. Walter's SST technology eliminates this porosity, creating an incredibly smooth surface that facilitates seamless chip evacuation. This reduction in friction is critical when drilling tough materials like stainless steel or structural steel, as it prevents work-hardening and extends the life of the cutter. The result is a tool that cuts faster, runs cooler, and lasts longer than conventional alternatives.

Beyond the surface treatment, the geometry of the 05A202 is optimized for modern magnetic drilling units. It features fully ground, extra-large flutes that channel debris away from the cutting zone efficiently. The modern tooth design bites into the material aggressively yet smoothly, requiring less horsepower from the drill motor. Equipped with a universal shank, this cutter is compatible with virtually all magnetic drill presses on the market, ensuring it fits seamlessly into your existing tooling inventory. Whether you are drilling aluminum, mild steel, or challenging stainless alloys, the Walter SST Core Cut delivers clean, burr-free holes with exceptional consistency.

Key Technical Benefits:

• Reduced Friction: Bronze SST finish minimizes heat buildup.
• Universal Compatibility: Fits standard magnetic drill arbors.
• Enhanced Durability: Resists wear even in stainless steel applications.
• Precision: Produces accurate, reamer-quality holes in a single pass.
