In this paper, the roughness of an HSS M42 and TiN coated tool that was used on aluminium alloy 7075 is the topic of discussion. While Group 1 was given an M42 high-speed steel tool, Group 2 received a control (Titanium nitride coated tool). From AA7075, twenty samples were taken from each group, and it was estimated that the material had a g-power of 80 percent. The dimensions of the sample were 25 millimetres in diameter and 15 millimetres in thickness. The rod with the grade 7075 is shorter in length and has a diameter of 25 millimetres. Its composition is lighter, and its length is 2 feet. The roughness test was carried out in a manner that was prescribed by the ASTM standards. For all of the statistical testing and analysis, SPSS was used. Based on the evidence, we are able to draw the conclusion that the tool made of high-speed steel had a mean surface roughness of 8.15625 m, but the tool made of titanium nitride coating had a mean surface roughness of 6.82665 m. (p0.020). Within the parameters of the investigation, it was determined that the surface roughness of the cutting edge titanium nitride coated tool was superior to that of the high-speed steel M42 drill tool.
