What is a Plunge Saw?

A plunge saw, also known as a track saw, is a versatile power tool that has become a game-changer in the world of woodworking and construction. Unlike traditional circular saws, which require starting the cut from the edge of the material, a plunge saw allows craftsmen to lower the blade directly into the material at any desired point, offering precise and clean cuts without the risk of splintering or damaging the workpiece.

The Inner Workings of a Plunge Saw

The magic of a plunge saw lies in its unique plunging mechanism. The conventional circular saws rotate the blade continuously, necessitating an edge-based start to the cut. In contrast, a plunge saw boasts an innovative design that allows the blade to be lowered or “plunged” into the material at any chosen point.

This means that the blade remains hidden within the saw’s housing until it is ready to make the cut. To achieve this, a plunge saw is typically used in conjunction with a guide rail or track. The guide rail acts as a guide for the saw, ensuring a straight and accurate cut.

When the user is ready to make the cut, they position the saw at the desired starting point on the guide rail, hold down the plunge release lever, and then lower the spinning blade into the material with a smooth and controlled motion. This plunging action ensures that the cut is initiated precisely where needed, avoiding any potential damage to the workpiece.
