Forstner bits and hole saws are both designed to drill "big holes." But, Selecting the right tool for the proper application demand an understanding of the tool.
If you're also likely struggling to work out which of the tools is right – and which of them you ought to choose for your job, read on.
Forstner Bit is named after Benjamin Forstner, who first patented the planning in 1886; Forstner bits allowed woodworkers to form holes without an extended "lead screw" without damaging the workpiece. Users can drill clean, flat-bottom holes with the Forstner bit.
The latest design of the Forstner bits is slightly different as they adopted a split-ring design and a "pointy tip" rather than the "lead screw." Their purpose remains largely an equivalent, though.
Drilled holes with absolute accuracy and cleanliness are achieved when Forstner bits are used with drill presses. That said, they will even be used with hand drills.
Hole Saw Bits are a bit like their name suggests, tools that cut holes. More specifically, they are doing it by rotating around their axis during a drill. As such, essentially, they're drill bits.
The hole bit is comprised of two parts:
The mandrel stands proud of the saw slightly and guides the saw blade into the wood. Usually, different-sized saw blades are often attached to one mandrel. Hole saws are available during an extensive variety of sizes starting from 1 inch, thanks to a couple of inches.
Because of their design, they are doing not produce wood chips when used. Instead, they cut out a round plug. That also means they only are often used for creating holes through a wood piece.
