Picture this: you're in the middle of a big fabrication project, and your regular drill bits are wandering, burning up, or leaving jagged edges that need extra cleanup. That's where this SALI 1-inch annular cutter steps in, making precise cuts like it's no big deal.
Standard twist drills often struggle with thicker materials, chipping away inefficiently and generating heat that dulls them fast. Annular cutters like this one work differently—they use a ring of teeth to shear out a perfect core, leaving a clean hole ready for bolts or pipes right away. This model's 1-inch diameter handles everything from 1/4-inch plates to 1-inch depths without breaking a sweat.
Made from high-speed steel (HSS) that's fully ground for sharpness out of the box, it bites into mild steel, stainless, aluminum, even cast iron. The 3/4-inch Weldon shank with two flats locks securely into your mag drill, preventing slippage under heavy torque. And that pilot pin? It's 1/4-inch diameter by 3 inches long, threading right into the cutter for spot-on alignment and easy core ejection.
Whether you're a welder punching holes for handrails, a mechanic fitting exhaust pipes, or a contractor prepping structural beams, this cutter speeds up your workflow. No more multiple passes or secondary deburring—pull out a smooth-sided hole in seconds. I've used similar ones on site, and they transform frustrating tasks into quick victories, especially when time's tight.
Pair it with coolant for even longer life on stainless or high-carbon steels. At this size, it's versatile for HVAC installs, tank fabrication, or even custom metal art projects. Grab one, and you'll wonder how you managed without it.
Key specs: 1" diameter, 1" depth, 3/4" Weldon shank, includes pilot pin. Engineered for pros who demand reliability.
