Nowadays, many of industry applied high speed drilling in their manufacturing process. The demand on time delivery and also increased manufacturing productivity has resulted in the recognition of high speed drilling process. High Speed Steel (HSS) is a common type of tool that use in manufacturing industries. The characteristic of HSS allowed itself to be one of the best tools because the toughness, impact strength, thermal shock resistance and also resist to fracture is better than the other type of tools. However, their implementation in high speed drilling is still questionable. The main objective of this project is to investigate the influence of cutting parameter such as cutting speed and feed rate on the surface roughness and tool wear in high speed drilling process. Commercially available High speed Steel twist drill bit of 7 mm diameter was used to drill holes on Aluminium block at the spindle speed range between 10,000 rpm to 18,000 rpm. From the results it was observed that higher spindle speed and low feed rate produced smoother surface. In addition high cutting speed and high feed rate gave higher tool wear rate. It is also found that HSS was not suitable to be used at spindle speed of 18,000 rpm.
