The experimental investigation on the effect of a spring on the rotation of conical picks was conducted for the first time. The combination of a spring and conical picks showed higher rotation, especially for a cutting depth of 5 mm. No precise conclusion was drawn regarding the effect of the skew angle on rotation. The spring experienced 4% permanent deformation as a result of 124 cutting tests.
