Abstract
A tool has a shank and a cutting blade mounted on the shank. The tool also includes an internal fluid passage for drawing in, together with air, chips produced when the cutting blade machines a workpiece. The internal fluid passage comprises a through hole made in the shank, at least one main inlet hole for drawing in the chips together with the air, the main inlet hole being made in the cutting blade and being in fluid communication with the through hole, and at least one sub-inlet hole for drawing in at least the air, the sub-inlet hole being made in the shank and being in fluid communication with the through hole. The chips can efficiently be discharged from the tool without being deposited in the internal fluid passage, by the air which flows at a suitable speed through the internal fluid passage and draws the chips, regardless of the diameter of the tool.
