Abstract (en)
A rotary cutting tool provided with an edge comprising a peripheral cutting edge and a side cutting edge. A flank 4 in the side cutting edge, of which the clearance angle in the direction of rotation is not more than 10 DEG , is finished to a surface roughness Rmax of 1 to 10 mu m, and the outermost surface thereof has a covering of one member selected from the group consisting of chromium and a nitride, a carbide, and a carbonitride of chromium. The above construction can eliminate the deposition of harmful gum on a cutting tool. The service life of this tool is at least 10 times longer than that of the conventional tools. This enables a high-speed tool steel to be used instead of a cemented carbide as an edge material, resulting in reduced cost. <IMAGE>
