Walter SST Core Cut 7/8-Inch x 1-Inch Annular Cutter

Precision Hole Cutting for Professional Welders

When your fabrication project demands precise, clean holes in heavy metal, the Walter 05A014 SST Core Cut Annular Cutter is the tool of choice. Sized at 7/8" diameter with a 1" depth capacity, this cutter is designed to outperform and outlast traditional twist drills. Unlike twist drills that must convert the entire area of the hole into chips, this annular cutter only cuts the periphery of the hole. This requires significantly less horsepower and thrust, allowing for faster penetration and less operator fatigue, especially when drilling overhead or in awkward positions.

The secret to its performance lies in the "SST" (Super Speed Tip) bronze surface treatment. This specialized coating provides a slick, non-stick surface that resists heat buildup—a common issue when drilling stainless steel and other tough alloys. Less heat means the cutting edges stay sharper for longer, giving you more holes per dollar. The geometry of the cutter includes spiral flutes that are fully ground to swiftly eject chips, keeping the cutting path clear and preventing the tool from binding in the hole.

This unit features a universal shank, ensuring it fits securely into the arbors of most standard magnetic drills and drill presses. It is an ideal solution for welders and fabricators working with structural steel, aluminum, or stainless plate. The hole quality produced is exceptional; the walls are smooth and accurate, often ready for bolting or welding immediately without extra cleanup. Whether you are retrofitting steel beams or fabricating custom machinery, the Walter 05A014 SST Core Cut ensures your holes are drilled quickly, accurately, and efficiently every time.
