05E102 - Walter SST Corecut 1-1/8 Inch Annular Cutter Universal Shank

High-Performance Drilling with Walter SST Corecut

The Walter 05E102 SST Corecut Annular Cutter is a premium cutting tool designed to deliver superior performance in metal fabrication and industrial maintenance. Sized at 1-1/8 inches in diameter with a 1-inch depth of cut, this cutter is engineered to penetrate tough materials with speed and precision. Unlike traditional twist drills that must remove all material from the hole, this annular cutter only removes a narrow ring of metal, significantly reducing the power required and the time taken to complete each hole.

Part of Walter's renowned SST (Super Speed Tip) series, this tool is manufactured from high-quality High Speed Steel (HSS) that has been specially treated to withstand the heat and stress of drilling through stainless steel and heavy structural steel. The unique geometry of the cutting teeth ensures smooth chip evacuation, preventing clogging and heat buildup that can shorten tool life. This results in a cleaner, burr-free finish that often eliminates the need for reaming or deburring.

Versatility is a key feature of the 05E102. It is equipped with a Universal Shank, making it compatible with a wide range of magnetic drilling machines, including those using Weldon or Nitto style arbors. Whether you are working in a fabrication shop or on a remote job site, this cutter provides the reliability and efficiency needed to maintain productivity. It is an essential accessory for welders and fabricators looking to maximize the capabilities of their magnetic drill presses.
