Although Cemented carbide drills are renowned for their excellent wear resistance and hardness, improper usage methods can significantly shorten their lifespan and even cause sudden blade breakage. Mastering the correct usage and maintenance methods is essential to fully realize the value of this efficient tool and ensure the processing quality and economic benefits. 

The proper use of standard Cemented carbide drills begins with accurate installation. Ensure that the drill bit is securely clamped in the drill chuck or tool holder without any shaking, as this is the foundation for maintaining drilling accuracy and preventing drill breakage. Before starting the drilling, it is crucial to select the appropriate drilling parameters based on the material of the workpiece. This includes the appropriate rotational speed (RPM) and feed rate. Generally, for processing hard materials, a lower rotational speed and feed rate should be chosen, while for softer materials, the parameters can be appropriately increased. Excessive parameters will generate excessive heat, while too low parameters may cause the drill bit to wear out rather than cut. 

Continuous cooling and lubrication can effectively extend the lifespan of the drill bit. Whenever possible, the use of cutting fluid or coolant oil can lower the cutting temperature, reduce the formation of chips, and improve the chip removal process. Especially when processing deep holes or working with brittle materials, the importance of cooling measures becomes even more prominent. 

Daily maintenance of the Cemented carbide drill cannot be ignored. After operation, the drill bit should be cleaned promptly to remove the tangled chips. Check for any obvious wear or chipping of the drill bit. Minor wear can be repaired by regrinding with professional tools and grinding machines, but heavy grinding requires professional skills and equipment to ensure the accuracy of the geometric angles. When the wear is severe or the chipping is large, it should be replaced in time to avoid affecting the processing quality or causing safety accidents. 

By focusing on key aspects such as installation, parameters, cooling and maintenance, operators can significantly enhance the performance of carbide drill bits, achieve better processed surfaces and a longer tool lifespan, thereby achieving reasonable control of production costs.
