1. For chip removal and coolant, machining workshops often use the method of injecting coolant from the outside to assist in chip removal. However, this method is only suitable for situations where the machining hole depth is smaller than the hole diameter and the cutting parameters are reduced. In addition, it is necessary to choose the appropriate type, flow rate, and pressure of coolant.

2. Processing cost: After the drill bit wears out, users do not need to replace the entire drill bit body, but only need to replace the hard alloy tooth crown. The procurement cost is only equivalent to the cost of welding or T301JIS spiral groove metric coarse thread series re grinding once. The precision of hard alloy tooth crown replacement is very high, and one drill body can be equipped with multiple tooth crowns in the processing workshop to process holes of different aperture sizes.

3. Stability, machine tool stability, and the service life and drilling accuracy of Coarse thread pitch are very important. Before processing, it is necessary to analyze and confirm the working conditions of the machine tool spindle, fixtures, and accessories. In addition, the stability of the drill bit itself should be fully considered. For example, Coarse thread specification have good rigidity and can achieve high processing technology accuracy, while hard alloy replaceable blade drill bits have poor structural stability and are prone to deflection during processing.

4. Precision: Hard alloy reversible blade drill bits are suitable for heavy-duty rough machining. Although the machining cost is usually lower than other types of drill bits, the machining accuracy is relatively low, with a tolerance range of 0-0.3mm (depending on the aspect ratio of the drill bit). They are generally used for hole machining with low precision requirements.
