This research is to study the cutting tools product in reverse engineering for turning milling and drilling included Tool holder Arbor and Insert tool. It is sampled the imported cutting tools from three areas worldwide composed with Sweden United State of America and Japan. The study emphasis in Arbor 136 mm. (6 tooth) Arbor 63 mm. (4 tooth) the changeable Insert tool typeTool bolder 20 mm. and Tool holder for turning. The result is found that Tool holder materials has the mixture of 0.387-0.437 %C hardness is 39.36-53 HRC which was full hardening. The price of Arbor (6 tooth) surveyed from four brands maximum is 22350 Baht and 2.41 times of price differentiation. The price of Arbor (4 tooth) surveyed from two brands maximum is 19000 Baht and 0.1-0.5 times of price differentiation. The price of Tool holder surveyed from three brands maximum is 14300 Baht and 0.15-0.55 times of price differentiation. And the price of Tool Holder for turning surveyed from four brands maximum is 1900 Baht and 0.5-1 times of price differentiation. The provider set up Tool holder and Insert tools will not be compatible together for marketing strategy. There are not much key player providers so there is no strong competition. The provider forces to distribute a set of 10 Insert tools and the most of Tool holder is Hardening and quenching not less than 39 HRC. The metal removal might be necessary use high technology and precision CNC Milling Machine. Therefore the study will lead to design and produce the prototype of cutting tools complete set which is compatible with Insert tools in all processes for turning milling and drilling. This cutting tools complete set differentiates from others because it helps to reduce costs reduce times and work comfortable. The development of compatible cutting tools complete set is the approach to reduce costs and times of work decrease maintenance costs and it will be the foundation to development of multi-function cutting tools complete set in place of the imported cutting tools.

Product development of End Mills AISI M42 tool steels products by cryogenics treatments after process by heating system through austenite structure had been conducted in order to increase effectiveness of wear resistance geometry designed in quenching figures quality of chip flow and improved by the cutting edge with sub-zero and heating system through producing the cutting tools on the rim of rake angle at 8° and 12° and 15° austenite temperature at 1210 ° C varied in room with temperatures at 35°C lower - 70 °C and -196°C respectively. The tempering at 535°C had been three time. End Mills figures then had been operated by 5 axis CNC grinding machine for the tools. The experiment had been conducted in accordance with the AISI 1045. Such as result revealed that stress relive of tools. it hardness between 67.7 up to 68.3 HRC and reduced I HRC. Having compared with the un-stress relief it revealed that on the 15° rake angle shear force increased 8° and 12° respectively. The result had denied the Shear theory however resisted against erosion better than 12° and 8°. The result revealed that cooling at - 196°C would help increase more 15% of cut effectiveness. Cooling treatment below 0° had tended to positively resist the erosion of the out tools. With its development of control of degrees of cooling substance acid the quality of products would be better increased. Such a result could be based of the development of product lines on highly-qualities cut tools which was domestically produced.
