About End Mills, according to the material, we mainly focus on general material, non-ferrous metal material and super hard material, and mainly focus on HRC45/HRC55/HRC65 which are the best tools. Since we changed our tungsten powder supplier last year with more stable quality and lower cost, we updated our price list in December last year, and we will continue with this price this year. We believe that many of our old friends are satisfied with our End Mills, because our cutting results are compared with Japanese and Korean brands like Kyrcera/Mitsubishi, and our cost is lower (about 20%-30% saving), so we welcome to try our products, and as a regular customer, we will try to get free samples to get a good start.
