Walter 3-1/2 Inch Carbide Tipped Annular Cutter 3 Inch Depth

Tough Cutters for Tough Jobs

When you are out on the job site facing a thick slab of cast iron or a heavy stainless steel plate, you don't have time for drill bits that dull halfway through the hole. The Walter 3-1/2" x 3" Carbide Core Cut is the heavy-hitter you need for your magnetic drill. This isn't your average cutter; it is built with extra-hard carbide inserts that chew through the hardest metals without breaking a sweat. If you are tired of burning up HSS bits or fighting to get through abrasive alloys, this is the upgrade your toolbox needs.

Speed matters when you are on the clock. The Walter 05D740 is designed to cut faster and cleaner, letting you move on to the next hole sooner. The secret lies in its aggressive body design and advanced fluting, which clears chips out of the hole instantly so the cutter doesn't bog down. This means you can push your feed rate harder with less effort, saving your arms and your machine. It is specifically designed to handle the heat and stress of drilling large 3-1/2 inch holes up to 3 inches deep, making it perfect for structural work, pipe fitting, and heavy machinery repair.

One of the biggest headaches in metalworking is trying to drill into a curved pipe or an uneven surface. Standard bits walk all over the place, ruining the finish and wasting time. The Walter Carbide Core Cut is designed to start clean even on irregular surfaces, giving you a perfect hole every time. Whether you are working with aluminum, copper, brass, or hardened steel rail, this cutter provides the reliability and durability professional welders and fabricators demand. Stop struggling with inferior tools and equip your mag drill with Walter's best.
