The MINI comes with a recommended end-mill for your material application. Softer materials need different end-mill bits than the harder materials. Our reliable engineers provide the best recommendation based on the type and hardness of the material that you will be milling and the overall milling volume. End-mills are all designed and manufactured entirely for tensile sample preparation needs. Therefore the longevity of each unit is exceptional to any comparable end-mill on the market. The average cost of end-mills is between $35.00 – $80.00 / bit. To save more there are bulk options available. To purchase these bits you can get them directly from TensileMill CNC by requesting a quote today. The tooling fixtures, which are provided properly and maintained, are designed to last for decades to come. Our experienced engineers will train your operators on preventative maintenance during the first day of training and installation. Additional preventative maintenance instructions are also provided with a detailed manual with all of the equipment.
