I've used plenty of drill bits that promise the world but leave you with jagged edges and flying chips. This SALI annular cutter changed that for my shop projects. At 1 inch in diameter with a matching 1-inch cutting depth, it powers through mild steel, stainless, or even cast iron using your magnetic drill press.
Twist drills wander on hard surfaces, chew up material in the center you don't need removed, and create heat that dulls them fast. For holes over 1/2 inch, they're a nightmare—slow, messy, and imprecise. You end up filing burrs or resizing everything, wasting time on the job site or in the garage.
Annular cutters work differently: they only cut the hole's perimeter, like a hollow boring tool. This one's high-speed steel (HSS) is fully ground for razor sharpness and longevity. The 3/4-inch Weldon shank features two flats to prevent slipping under high torque—no adapters needed. Plus, the included 1/4-inch by 3-inch pilot pin centers it perfectly, starting holes dead-on without walk.
Cuts 5-10 times faster than twist drills, with minimal swarf so your workspace stays cleaner. Holes come out burr-free on both sides, ready for welding or threading right away. It's durable too—I've run dozens of holes in structural steel without resharpening. Less downtime means more done in a day.
Whether you're fabricating railings, installing HVAC ducts, mounting machinery, or building custom trailers, this cutter handles it. Stick it in your mag drill, squirt some coolant, and watch it chew through 1/4-inch plate in seconds. Pairs great with other sizes for a full hole-making kit. If you're serious about metalwork, this 1-inch annular cutter belongs in your toolbox.
Grab one and feel the difference in your next project—precision holes, every time.
