The central focus of this study was to assess the efficacy of the material removal rate (MRR) with respect to high-speed steel (HSS) and carbide cutting tools utilized in CNC (Computed numerical control) drilling operations of AA6063 with SiC (Silicon carbide) and TiO₂ (Titanium dioxide) alloys. In this investigation, AA6063 was selected as the base material. The reinforcement materials are SiC (5%, 10%, and 15%) and TiO₂ (5%). Two groups were used for this statistical analysis: one is experimental group performed using carbide tool and the second is control group preferably HSS tool. The SPSS (Statistical Package for the Social Sciences) software statistical analysis was performed for statistical analysis. Stir-casting methods have been used to fabricate hybrid metal matrix composites (MMCs). The total sample size of 40 was calculated by keeping the alpha value 0.05 and G-power at 80%. The study’s results indicate that the maximum MRR of 2800 mm³/min was attained under specific cutting conditions, namely feed rate of 0.06 mm/rev, spindle speed of 2800 rpm, and 10% SiC reinforcement. Furthermore, statistical analysis revealed that the carbide tool outperformed the HSS tool in terms of MRR with a 95% confidence level and a two-tailed significance value of p = 0.000, which is below the threshold of 0.05. A substantial significance between the two groups is evident from the results. Furthermore, it was observed that the average value of MRR from the drilled hole exhibited an upward trend for carbide tools while a downward trend was observed for HSS tools with an increase in the particle content. Notably, in terms of MRR, carbide drill tools surpassed all other tools tested and were the most efficient.
