Drill bits are cutting tools used to remove material to create holes over a cross-section. Drill bits are brake when they can run at rated speed or rated load of drilling machine [1]. Drill bits are in many sizes and shape and can create different kinds of holes in many different materials. Many hard materials, such as carbides, are much more brittle than steel, and are far more subject to breaking.3D model can design with the help of CATIA V5 R20, this design can analysis in ANSYS [2] software and in this 3type of materials can use, like high-speed steel, aluminium silicon carbide. After analysing the results in ANSYS and those results are comparing with each material and conclude which is better suitable for the drill bit that one will go to machining process to model. Fabrication of twisted drill mix-up with 5-7 percentage of cobalt with high-speed steel and aluminium silicon carbide. To compare the results of both of them, give the better results of twisted drill by wear and hardness of materials.

Keywords : drill bit, CATIA, ANSYS.
