Forstner drill bit has a flat hole at the bottom that makes it possible for various hardware installations that require precision for depth and mortise joint. The feature makes it possible to drill holes in difficult angle, overlapping holes, and for making holes on the material edges.

The Forstner drill bit was an invention of Benjamin Forstner sometime in the 1800s. He made a cutting rim or teeth-like structures surrounding the perimeter. The original invention had a sharp projection at the center. The drill works with bits of up two 2-inches in diameter but cannot be smaller than 1-inch.

On the downside, the Forstner drill bit tends to slide on the surface of the material you are working on. For the best results and limit skidding on the material surface, use it as a drill press. Otherwise, the Forstner drill to drill overlapping joints because the outer cutting rim controls slipping into the next hole.

The bit is stable when you use a drill press, you can get straight and true edges when drilling a hole that is partially exposed. It is even possible to say that the beat came way ahead of its time because the nature of work the bit is handling came in many years after its invention.

A wide outer rim guides the Forstner bit, which is not common with other bits that follow the tip. The wide outer rim is useful when you want to drill holes angles that overlap as well as holes on edge.

Forstner bits are suitable for drilling overlapping guided angled holes on rectangular mortise or on materials that require precision bonding. The bit seems to be the only choice for neat and large holes, making the prospect of owning a Forstner bit a reality.

Guiding the Forstner Bit With a Portable Drill

Get at least a plywood or a scrap of wood about ¾ inches thick.

  • Two clamps for holding the bit in position.
  • Cut a piece of wood from the scrap or the plywood to a usable size and leave room for clamping.
  • Setup the drill and fix the Forstner bit. Make adjustments to ensure the bit will go all the way to the desired depth.
  • Clamp the wood on the surface where drilling will take place. Confirm that the Forstner bit is long enough to cut through the entire board.
  • Drill the hole through the piece. The bit may skid but not far enough to interfere with your work. Once the bit passes to the other side, keep drilling until you are satisfied with the size of the hole.
