05A108 - Walter SST Corecut 1-1/2 Inch x 1 Inch Depth Annular Cutter

High-Performance Industrial Core Drilling

The Walter 05A108 SST Corecut Annular Cutter is a premium tooling solution designed for heavy-duty fabrication and industrial maintenance applications. Engineered with a 1-1/2" diameter and a 1" depth of cut, this cutter utilizes Walter's proprietary Super Speed Tip (SST) technology. The advanced bronze surface treatment significantly reduces friction at the cutting interface, preventing heat buildup that typically degrades standard high-speed steel (HSS) cutters. This results in a tool that maintains its hardness and cutting edge longer, even when processing tough materials like stainless steel and structural alloys.

Efficiency is critical in production environments, and the SST Corecut delivers by eliminating the need for pilot holes or step drilling. Its fully ground, extra-large spiral flutes ensure rapid chip evacuation, preventing clogging and binding deep in the cut. The universal shank design makes this cutter compatible with virtually all magnetic drilling units on the market, including those with quick-change arbors. Whether drilling on flat plate, pipe, or uneven structural beams, the 05A108 provides consistent, burr-free performance that reduces secondary finishing operations.

Technical Superiority

The unique tooth geometry of the SST Corecut series is optimized to balance cutting forces, reducing machine load and operator fatigue. By cutting only the periphery of the hole and ejecting a solid slug, this tool requires less power and time than solid twist drills. It is an essential asset for fabrication shops, steel erectors, and MRO departments requiring precision and speed.
