average tool life of hss end mill
End mills are tools used for milling in diverse directions to remove material from a workpiece. 1 8 ball nose end mill 1 4 shank have distinctive shapes and sizes, most of them composed of high speed steel (HSS). This type of steel presents a significant hardness and can withstand wear and tear. End mills are suitable for a broad range of materials, from timber and plastic to metal works.

On average, a high-speed steel end mill is capable of shaving through a thousand square inches (6.45 square metres) of material before requiring replacement - a tool life lasting 1000 hours. The longevity of the end mill, however, varies dependant on the materials being cut, the speed of operation, its feed rate and depth of cut.

If the speed of the end mill is increased, this will cause it to wear down faster as its cutting edges come in contact with more friction. Additionally, the feed rate, which is the velocity of the end mill in relation to the material being cut, also has an effect on its longevity if it is lifted to a too-high speed. On the other hand, shallow depth of cut which is the sum total of material being cut will widen the life of the end mill.

Achieving the desired results in your milling operations is highly dependent on the type of end mill you use. HSS end mills offer a strong and reliable solution, capable of accomodating various materials while having an impressive tool life of 1000 hours. This makes them a suitable and cost-effective choice for all your milling needs.
