Swozzto 2-Pack Forstner Bit Extension Set – Anti-Slip, 3.28-inch and 5.64-inch Depth

Meet the Swozzto 2-Pack Forstner Bit Extension Set, crafted for woodworkers who need extra depth without a new drill guide. This pair adds 3.28-inch and 5.64-inch drilling depths, opening possibilities for deeper pockets, mortises, and precise recesses in timber, panels, and furniture components. The extensions integrate smoothly with standard drills and Forstner bits, delivering dependable alignment and a clean finish as you work through hardwoods and soft woods alike.

Each piece is built with a rugged high carbon steel body and a 3/8 inch inside diameter. The design couples durability with a precise fit so you can plan longer cuts with confidence.

A note to check bit shank size before use ensures you are pairing the extension with the right bit to minimize any shifting during operation.
