Mongtec SK 熱縮式刀把（內冷）
熱縮式靠的是過盈配合：加熱刀把讓夾持孔脹開，放入刀桿，冷卻後整圈孔壁抱住刀桿。沒有任何中間零件，所以跳動最小、夾持力最高、刀具擺長也最短，高速精銑與小徑刀具最吃這個優勢。代價是換刀要有加熱設備，而且刀桿公差必須是 h6 —— 這兩點在下單前要先確認。
SK 對應 DIN 69871 形式，歐系機台常見。本頁是內冷（through coolant）版本：切削液沿刀把內部通到刀尖，深孔鑽削與高速加工的排屑與刀具壽命差別最明顯。
Mongtec Precision 為台灣品牌，台中設計製造。
關於留白的格子。表格裡印「— RFQ 時確認」的欄位，是型錄本身印刷有問題、我們無法確認的數字。能與其他印得正確的頁面兩相對照確認的才填回去；只要有一個環節無法證明就留白 — 我們不猜。
介面規格要先確認。刀把的錐柄、拉釘與法蘭槽是配機台主軸做的，形式不同不可混用。詢價時請提供機台型號與主軸規格，我們對照圖面確認後再報價，這道確認不收費。
