[citation needed] Biscuits are predominantly used in joining sheet goods such as plywood, particle board and medium-density fibreboard.
Typically, the machine will have an adjustable fence, so it can be set on an angle for joining mitered pieces.
Also, there are other types of specialty biscuits available, from metal connectors, used for removable panels, to hinges, making these portable machines even more flexible.
The operator aligns the machine and uses firm pressure to push the body forward against the base plate to make the cut.
Because the slots are slightly longer than the biscuits, it is still possible to slide the panels sideways after the joint is assembled (before the glue sets).
This fact makes the biscuit joiner easy to use, because it does not require extreme accuracy or jigs to achieve perfect joints.
Some models allow slots to be cut at angles other than 90° to the joining face, for example 45°, which greatly speeds up the assembly of things like cabinets.
