Forstner Drill Bits (Woodworking Precision Tools)

Forstner bits are specialized drill bits designed to cut clean, flat-bottom holes in wood—something standard twist drills or spade bits can’t do well. What makes them different Flat-bottom holes → ideal for precise depth work Clean edges → minimal tear-out Can overlap holes → useful for slotting No center breakthrough required → can drill partial holes That’s why they’re widely used in furniture and cabinet work. Common uses Cabinet hinges (especially 35mm concealed hinges) Furniture joinery (dowels, mortises) Wood plug cutting Recessing bolts or hardware Drilling large, neat holes in plywood or MDF Sizes available Typical sets include: Small: 10mm – 25mm Medium: 26mm – 40mm Large: up to 60mm+ The 35mm size is the most popular (hinge installation).
