Design and Development of an Attachable Sharpening Tool Bit Holder A Utility Model

This study focused on the design and development of an Attachable Sharpening Tool Bit Holder for mechanical technology. Specifically, the study focused on determining the accuracy of the angle produced by the device when performing an operation. Moreover, perceived cost-effectiveness and device safety. This research study uses the descriptive- developmental research method with 51 respondents who were determined using the purposive sampling. The data were gathered from the respondents using the researcher-made questionnaire. Result revealed that the mean absolute error for the attachable tool bit holder is 0.13. Respondents of the survey rated strongly agree on the cost-effectiveness and the device safety of the Attachable Tool Bit. Meanwhile, the operational safety of the Attachable Tool Bit Holder was rated as very much safe by the respondents. There is a significant difference in the angle accuracy, duration, and operational safety between the Attachable Tool Bit Holder compared to the old design. Thus, the device is recommendable to use in mechanical shop rooms in industry and academe and to be registered as utility model.
