The objective of this research project was to estimate the effect of the shape of the cutting link and the value of the inclination angle of the cutting edge of the horizontal blade on machining performance. The performed experiments comprised two types of saw chains with cutting links of chisel and semi-chisel types with the following five variants of the inclination angle: 20°, 25°, 30°, 35° and 40°. Investigations carried out by the author showed a statistically significant influence of both the shape of the cutting link and the size of the inclination angle of the horizontal blade on unit machining output. Higher outputs were obtained by saws with chisel toothing and the best variant in both types of saws was the variant with the 35° angle.
