Ingco 5-Piece Wood Drill Bit Set | Carbon Steel Brad Point Boring Bits for Carpentry and Furniture Assembly (AKDB5055)

The Ingco AKDB5055 Wood Drill Bit Set is a precision-machined 5-piece collection of specialty brad-point (spur point) drill bits engineered specifically for boring crisp, splinter-free holes in softwoods, hardwoods, plywood, chipboard, and MDF panels. Designed with standard straight cylindrical shanks, these bits provide universal compatibility with traditional three-jaw manual and keyless chucks found on corded impact drills and cordless drill drivers.

Each bit features a central guiding spur point that firmly anchors the bit on your exact mark, eliminating bit walking or drifting when initiating the cut. Flanking the center point are two sharp side cutting spurs that score the circumference of the wood grain before the main lifting edges remove material. This mechanical sequence prevents grain tear-out on the entry surface, ensuring smooth profiles and flat-bottomed precision. Deep, wide-flute spiral spacing rapidly evacuates sawdust and wood chips up out of the bore channel, minimizing friction heat, keeping the edges sharp, and reducing drag on the drill motor.
