Chop saw

A chop saw power tool for cutting metal, the chop saw power tool comprising a saw base and a cutting head assembly,

• the saw base comprising:
• a support structure;
• a workpiece support table comprising a workpiece support surface arranged to receive a workpiece to be cut in a cutting operation;
• and
• rails connected to the workpiece support table,
• the workpiece support table being rotatable in a plane of the workpiece support surface through a predetermined angular range relative to the support structure to select an angle of cut of the workpiece,
• the cutting head assembly comprising:
• a circular cutting blade arranged on the cutting head assembly and having an axis of rotation such that the circular cutting blade rotates within a cutting plane arranged in a fixed orientation perpendicular to the plane of the workpiece support surface,
• wherein the cutting head assembly is pivotable relative to the saw base in a direction parallel to the cutting plane between a position where the cutting blade is remote from the workpiece and a position where the cutting blade is in contact with the workpiece,
• wherein the cutting head assembly is slideably mounted on the rails and is linearly moveable relative to the workpiece support table to adjust a cut position of the cutting blade on a workpiece;
• and
• wherein the chop saw power tool further comprises an interlock configured to secure the cutting head assembly in a plurality of discrete linearly-spaced fixed positions on the rails, relative to the workpiece support table prior to a cutting operation;
• wherein the rails are connected to an end block at one end, and fixedly connected to the workpiece support table at an opposite end.
