Abstract (2. Language): 
In this study, drill operations have been tested on Sleipner cold work tool steel by various machining parameters and drill bits. Solid Carbide Uncoated drill bits and TiAlN Coated reamed drill bits were used in experiments. Both drill bits were machined on Sleipner steel with four different cutting speeds. After machining, thrust forces and moments values generated during cutting, consisting surface and the hole qualities have been measured. Drilled by reamed drill bit’s hole gave better results quality as a result of the studies. It was reached as conclusion that the optimum values parameters of the cutting speeds are between 40 to 42 m/min for both the drill bits.
