筒夾是一種圓筒狀、外錐內直的彈性夾具，通常搭配螺帽或壓蓋安裝於刀把之中，當螺帽鎖緊時會使筒夾產生均勻收縮力，牢牢抓住刀具柄部。這樣的設計讓筒夾能在高速旋轉下穩定夾持工具，達成高重現性與低偏擺的理想加工條件。可搭配多種刀把型號即可對應不同柄徑刀具，提高系統靈活度與成本效益。

Cryogenic Treatment
The Austenite remaining inside the knife can be turned into Martensite, and its variable structure can reach 97% ~ 98%. The picture on the right is a metallographic diagram of two pieces of the same material but different heat treatment. If the knife handle is treated with cryogenic treatment, its life and stability far exceed those of untreated material. The company's products are HY, CR, PFC and so on.
