2-1/8 x 3-1/2 Forstner pattern bit gives you a dedicated bit for drilling 2-1/8 inch diameter holes in wood, so you can handle pocket-holes and flat-bottom holes where a precise size matters for your layout or hardware fit. This Amana Tool Forstner bit has a 3/8 inch shank, which lets you run it in any 3/8 inch or larger portable drill or stationary drill press, so one bit can serve both shop and jobsite setups. The Forstner pattern design is known for drilling clean and chip-free holes in wood, which reduces blowout around the edge of the hole and leaves a neater surface for plugs or fittings. Amana Tool uses high quality tool steel that is precision machined and ground, so the cutting geometry is consistent and helps the bit track accurately in repetitive drilling. Large gullets are milled into the tool body to clear chips efficiently, keeping the cutting edges engaged instead of clogged.
This Amana Tool Forstner bit is designed to drill pocket-holes and flat-bottom holes using any 3/8 inch or larger portable drill or stationary drill press, so it adapts to common shop equipment without special tooling. The Forstner pattern design produces flat-bottom holes in wood, and a small pilot hole used for centering will be present on those flat-bottom holes, which gives you a positive center reference while leaving only a minor point at the bottom that is easy to account for in your layout. Using a portable drill lets you take the 2-1/8 inch diameter directly to assembled work in the field, while a drill press offers more control for repetitive drilling in shop runs.
The FO-540 Forstner bit is intended for woodworking applications where 2-1/8 inch diameter holes are required, so it suits tasks like pocket-holes or flat-bottom recesses that must stay within that size. Because the bit drills clean and chip-free holes in wood, it works well when the edge of the hole remains visible or supports a part that benefits from a smooth bearing surface. The ability to operate in any 3/8 inch or larger portable drill means you can bring the 2-1/8 inch cutting capacity to larger assemblies, doors, or casework that cannot be moved easily to a drill press. When mounted in a stationary drill press, the same Forstner pattern geometry helps maintain consistent hole placement across production runs where accuracy between parts is important.
Amana Tool uses the finest quality tool steel that is precision machined and ground, which produces cutting edges and a bit body that are uniform, supporting accurate tracking as you repeat the same hole pattern. The Forstner pattern cutting approach is known for delivering clean, chip-free holes in wood, and that reliable cut quality helps reduce sanding or clean-up time around each 2-1/8 inch opening. Large gullets milled into the tool body provide exceptional chip clearance, allowing chips to move away from the cutting edges so the bit can continue to cut efficiently through deeper material. The small pilot hole used for centering on flat-bottom holes adds a built-in reference point during drilling, which keeps the bit located where you want it in your layout while leaving only a minor mark at the base of the hole.
The FO-540 Forstner bit drills a 2-1/8 inch diameter hole, which is useful when your work requires that specific size across multiple parts.
This Amana Tool Forstner bit works in any 3/8 inch or larger portable drill or stationary drill press, so it handles both mobile and fixed drilling setups.
