05A106 - Walter SST Core Cut Annular Cutter 1-3/8 Inch x 1 Inch Depth

High-Performance Drilling with Walter SST Core Cut Technology

The Walter 05A106 SST Core Cut Annular Cutter represents the pinnacle of drilling efficiency for industrial fabrication. Designed with a diameter of 1-3/8 inches and a cutting depth of 1 inch, this tool is engineered to tackle the toughest materials, including stainless steel, aluminum, and heavy structural steel. What sets the SST series apart is Walter's proprietary Special Bronze Surface Treatment (SST). This advanced coating drastically reduces the coefficient of friction between the cutter and the workpiece. By minimizing heat generation at the cutting interface, the tool maintains its hardness longer, preventing premature dulling and ensuring consistent performance over hundreds of holes.

Beyond the surface treatment, the physical geometry of the cutter is optimized for heavy-duty use. It features fully ground, extra-large flutes that facilitate rapid chip evacuation. In deep hole drilling, chip packing is a common cause of tool failure; the SST Core Cut design ensures that swarf is ejected efficiently, keeping the cutting path clear and reducing the load on your magnetic drill. The modern tooth design further enhances cutting speed, allowing for smooth, chatter-free penetration that leaves a burr-free finish, often eliminating the need for secondary reaming or deburring operations.

Versatility is key in MRO and fabrication environments. This cutter is equipped with a universal shank, making it compatible with virtually all major brands of magnetic drilling units and stationary drill presses. Whether you are working on-site erecting steel structures or in a machine shop fabricating precision components, the Walter 05A106 delivers reliability and precision. Its robust construction allows it to be resharpened, providing excellent cost-per-hole value over the life of the tool.

Key Technical Benefits

• Heat Management: SST coating acts as a thermal barrier and lubricant.
• Chip Removal: Spiral flute design prevents clogging in deep cuts.
• Material Versatility: Equally effective on ferrous and non-ferrous metals.
