05A406 - Walter SST Core Cut 1-3/8" x 2" Annular Cutter with Universal Shank

High-Performance Drilling with Walter SST Corecut Technology

The Walter 05A406 1-3/8" x 2" SST Corecut is a premium annular cutter designed to meet the rigorous demands of modern metal fabrication. Engineered by Walter Surface Technologies, this tool represents a significant leap forward in hole-making efficiency. The defining feature of this series is the Super Speed Tip (SST) surface treatment. This advanced fabrication process eliminates microscopic porousness on the cutter's surface, resulting in a flawlessly smooth finish that drastically reduces friction during operation. For industrial operators, this means less heat generation, reduced wear on the tool, and a significantly extended lifespan compared to conventional uncoated cutters.

Beyond the surface treatment, the geometry of the Walter SST Corecut is optimized for heavy-duty performance. It features fully ground, extra-large flutes that facilitate rapid chip evacuation—a critical factor when drilling deep holes in gummy materials like aluminum or tough alloys like stainless steel. The contemporary tooth design bites into the material aggressively yet smoothly, requiring less horsepower from the magnetic drill unit. This efficiency not only speeds up production cycles but also reduces mechanical stress on your drilling equipment.

Versatility is key in a busy workshop, and the 05A406 delivers with its universal shank design. It is compatible with a wide range of magnetic drilling units and stationary machines, making it a go-to solution for diverse applications. Whether you are working with structural steel, stainless steel plate, or aluminum components, this cutter provides precise, burr-free holes with a 1-3/8" diameter and a 2" depth of cut. It is the ideal choice for professionals seeking reliability, speed, and precision in their metalworking operations.

Key Industrial Benefits

• Extended Tool Life: The SST treatment minimizes friction and heat buildup, preserving the cutting edge for longer periods.
• Superior Finish: Produces clean, accurate holes that often require no secondary deburring or reaming.
• Broad Compatibility: The universal shank ensures it fits most standard magnetic drills without the need for adapters.
