The relationship between cutting speed and durability of Tap drill

The durability of Tap drill is a comprehensive indicator that characterizes the cutting performance of Tooling tapping materials. Under the same cutting conditions, the higher the durability, the better the wear resistance of the materials used in Tap drill.

When comparing the machinability of different workpiece materials, the durability of Tap drill is also an important indicator. The higher the durability of Tap drill, the better the machinability of workpiece materials.

The lifespan of an Tooling tapping refers to the total cutting time from the time a new YAMAWA Tooling tapping is put into use until it is scrapped, including multiple regrinding cycles. Therefore, the lifespan of an Tooling tapping is equal to the product of its durability and the number of regrinding cycles.

Through the wear experiment of Tap drill, it is known that the cutting speed is the most important factor affecting the durability of Tap drill after determining the workpiece material, Tap installation material, and geometric parameters of Tap drill.

By increasing the cutting speed, the durability of Tap drill will decrease, and this relationship can be obtained through the single factor method in experiments (keeping other cutting conditions constant and only changing the cutting speed).
