Electric planers with a edge guide

Quarter sampling

— the presence of the function of sampling a quarter in the design of the electric planer. The selection of a quarter can be described as cutting a groove along the edge of the board — thus, instead of a protruding corner, a rectangular recess is obtained. For such work, planers use a special device — a parallel stop: it allows you to move the tool strictly along the edge of the board, ensuring accurate cutting of a quarter groove. If in this model the possibility of sampling a quarter is claimed, this, usually, means that the parallel stop is initially supplied in the kit.

Theoretically, a quarter can be sampled with almost any planer, without a special stop. However, in fact, in order to achieve this more or less tolerable quality, a very high level of skill is required, while even a beginner can cope with such a task with the presence of a parallel fence.
