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.
