05A506 - Walter SST Corecut Annular Cutter 2-3/8 Inch x 2 Inch Depth

High-Performance Drilling with Walter SST Corecut Technology

The Walter 05A506 SST Corecut Annular Cutter represents the pinnacle of hole-making technology for industrial fabrication. Designed with a substantial 2-3/8 inch diameter and a 2-inch depth of cut, this tool is engineered to handle the most demanding structural steel and metalworking applications. The defining feature of the SST (Super Speed Tip) series is its exclusive bronze surface treatment. This advanced coating significantly reduces friction and heat buildup during the drilling process, which is critical when working with work-hardening materials like stainless steel or aluminum. By maintaining a cooler cutting edge, the tool retains its hardness longer, ensuring extended service life and consistent performance shift after shift.

Efficiency in metal removal is achieved through Walter's precision engineering. The cutter features fully ground, extra-large flutes that facilitate rapid chip evacuation. In deep hole drilling, chip packing is a common cause of tool failure and poor surface finish; the SST design eliminates this issue, allowing for continuous drilling without the need to constantly retract the tool to clear debris. The modern tooth geometry is optimized to bite cleanly into the material, reducing the thrust load required by the magnetic drill unit and minimizing vibration. This results in a smoother operation that is less taxing on both the machine and the operator.

Versatility is key in a busy workshop, and the 05A506 delivers with its universal shank design. This feature ensures compatibility with a wide range of magnetic drilling units and stationary machines, making it a flexible addition to any tool crib. Whether you are drilling through structural beams, plate steel, or fabricating custom machinery, this annular cutter produces accurate, burr-free holes that typically require no secondary finishing operations. The elimination of porosity and the achievement of a mirror-like finish inside the hole demonstrate the superior quality of the Walter SST manufacturing process.

Invest in the Walter 05A506 for your heavy-duty drilling needs and experience the difference that premium surface treatments and geometry make. It is an essential tool for fabricators who demand speed, precision, and longevity from their consumables.
