PROBLEM TO BE SOLVED: To provide an economical cutting device with a cutting tool capable of suppressing the supply amount of cutting fluid in comparison with a conventional cutting device with the cutting tool.SOLUTION: A cutting device with a cutting tool includes a chuck table for holding a work, and a cutting tool cutting means having a spindle, a motor for rotating the spindle and a cutting tool wheel which is attached to the distal end of the spindle and which includes a cutting blade for cutting the work held on the chuck table. The spindle includes, at the center, a first cutting fluid supply path connected to a cutting fluid supply source. The cutting tool wheel includes a wheel base attached to the distal end of the spindle, and a cutting tool shank having a cutting blade attached to the wheel base. A second cutting fluid supply path one end of which is joined to the first cutting fluid supply path disposed at the center of the spindle and the other end of which is joined to a jetting port for jetting a cutting fluid toward the cutting blade is formed inside the wheel base. |
