“…Using the wrong type of bit for a particular material can damage the bit and result in subpar drilling results. For drilling hard materials like metal or masonry, choosing high-quality HSS or carbide-tipped drill bits is generally advisable, as they are less likely to be easily damaged and perform better [9]. The gasket is inserted into the jig and stacked in four layers.…”

The Ge Nose C19 medical device gasket is a product from a manufacturing company in Yogya. Gaskets must be of good quality to ensure vacuum or prevent air leakage from entering the test chamber. The core problem in the production process is the quality problem of many rejects and the quantity not yet meeting the production target. The observation results show that the gasket reject problem is found in the four holes that are formed, which do not match the dimensions or are torn. Making four holes in the gasket made from neoprene rubber is done through a drilling process, which can risk tearing or damage. The type of drill bit used can affect the success of drilling gasket holes. The process of making four holes in the gasket using the piercing method is thought to be able to increase the quality and quantity of gasket products. This research aims to increase the quantity and quality of Ge Nose 19 medical device gaskets using a piercing tool. Research methods include problem identification, literature study, design, manufacture, and testing of piercing tools. The test parameters are time and product quality, namely the shape and position of the hole. The results of this research show a reduction in the cycle time of the hole-making process by 53.7%, so production capacity has increased by 51.8%. The quality of gasket production has increased; of the 40 samples tested, 0 gaskets were rejected.

This article investigates the effect of different drilling forces on drill bit wear and their effects on drilling time within the context of the development of a drilling robot for on‐site construction applications. The study explores variations in three force levels (80, 120, 160 N), three directional orientations (upwards, downwards, horizontal), four drill bit diameters (8, 10, 12, 16 mm), and two concrete strength types (C25/30, C70/85). The findings indicate that while there is little divergence in drill bit wear across force levels, the influence of concrete strength is undeniable. Furthermore, drilling time increases, by 7 % to 11 % after 37.5 m drilling depth and up to 68% after 150 m depending on the drilling configuration. In conclusion, the study reveals a notable discrepancy between the progressive increase in drilling time and the relatively stable progression of drill bit wear, particularly in achieving code‐compliant boreholes.
