This paper rigorously examines drilling operations in a jute/palm fiber reinforced polyester composite (15 % palm fibers, 15 % jute fibers, 70 % polyester resin, 9 mm thickness), emphasizing factors affecting hole quality. The hole quality was characterized by assessing circularity, cylindricity, and delamination. The key findings include the identification of optimal cutting conditions, where a feed rate of 0.08 mm/rev and a spindle speed of 1592 rpm maximize circularity and cylindricity. Furthermore, a lower feed rate (0.04 mm/rev) to be optimal for minimizing delamination, circularity and cylindricity, underscoring the significance of precise adjustments. The influence of drill types is highlighted, with the High-Speed Steel twist drill emerging as the superior choice, demonstrating enhanced performance. The study also reveals the sensitivity of delamination to feed rate variations, emphasizing its primary role in material damage. Cyclical trends in circularity and cylindricity are observed, with feed rate standing out as the predominant factor affecting precision.
