The present invention provides a high efficiency cutting tooth. The cutting tooth reduces cutting resistance or has a spin function, a high cooling efficiency, and a long service life, and comprises a cutting tooth block and a cutting tooth head. The cutting tooth is characterized in that: connected to the cutting tooth block is the cutting tooth head, 1 constituted thereon are a conical or ball nose cutter and an encircling conical block or an encircling arced block or a crack-resistant composite encircling conical block or a crack-resistant composite encircling arced block having a groove arranged thereon; 2 the encircling conical block or the encircling arced block or the crack-resistant composite encircling conical block or the crack-resistant composite encircling arced block has protrudingly arranged thereon the conical or ball nose cutter; 3 being in a staggered arrangement, at least one level of the encircling conical block or the encircling arced block or the crack-resistant composite encircling conical block or the crack-resistant composite encircling arced block has arranged thereon a groove or a crack-resistant composite groove or a dextrorotatory or levorotatory spiral groove or crack-resistant composite spiral groove; 4 the encircling conical block or the encircling arced block has arranged thereon a cutting blade or a crack-resistant composite cutting blade, a spare cutting blade, and a cutting face; 5 the cutting blade or the crack-resistant composite cutting blade has arranged thereon a slitting blade, and at least one row of the cutting blade or of the crack-resistant cutting blade has arranged thereon an indented blade or a crack-resistant composite indented blade.
