05A102 - Walter SST Core Cut Annular Cutter 1-1/8 in. x 1 in. Depth

High-Performance Walter SST Core Cut Annular Cutter

The Walter 05A102 SST Core Cut Annular Cutter is a premium drilling solution designed for industrial fabrication and heavy-duty maintenance operations. Engineered with Walter's proprietary Super Speed Tip (SST) technology, this 1-1/8" diameter cutter is built to handle the toughest materials, including structural steel, stainless steel, and aluminum. The defining feature of this tool is its specialized bronze surface treatment. Unlike standard high-speed steel cutters, the SST coating effectively eliminates microscopic porosity on the tool's surface. This results in a flawlessly smooth finish that drastically reduces friction during operation, preventing overheating and ensuring the cutter maintains its hardness over a longer lifespan.

Efficiency is at the core of the 05A102's design. It features fully ground, extra-large flutes that facilitate rapid material evacuation. In deep hole drilling, chip buildup can often cause binding or breakage; however, the optimized geometry of the SST Core Cut ensures that swarf is ejected smoothly, allowing for continuous, uninterrupted drilling. The modern tooth design further enhances performance by distributing the cutting load evenly, which minimizes vibration and produces a clean, burr-free hole that rarely requires secondary finishing. This makes it an invaluable asset for workshops looking to maximize throughput and minimize downtime.

Compatibility is key for diverse industrial environments. This cutter is equipped with a universal shank, making it compatible with a wide range of magnetic drilling units and stationary machines. Whether you are working on-site erecting structural steel or in a fabrication shop processing stainless components, the Walter SST Core Cut delivers consistent, reliable precision. By choosing this cutter, you are investing in a tool that not only speeds up the drilling process but also reduces the total cost per hole through its exceptional durability and resistance to wear.
