Through-tool coolant was applied to the drilling of an aluminum/SiC MMC. Titanium nitride coated, solid carbide drills were used to investigate the effect of the coolant application method on the performance of the drilling operation. Holes were produced dry, with conventional coolant and with through-the tool coolant. The results provided strong evidence that the conventional application of coolant was having no beneficial effect on the cutting operation compared to dry drilling. However, through-tool cooling gave a significant improvement in performance in terms of tool wear, cutting forces, surface finish and the height of the burrs produced. [S0094-4289(00)02104-6]
