    摘要： The present invention relates to an insert for slot milling, and more specifically, to an insert for slot milling which can smoothly form a front end surface of a concave portion of a slot formed at a cutting target, and provides a safe use thereof by preventing the erroneous installation of cutting inserts coupled with insert-installation seats on both sides of a milling cutter body to prevent damage of the cutting inserts and the milling cutter. To this end, the present invention is characterized in that the plurality of cutting inserts are provided around the slot milling cutter body, one of two cutting inserts protrudes with respect to one side of the milling cutter body and the other protrudes with respect to the opposite side of the milling cutter body, and two cutting inserts are formed with different structures to prevent the erroneous installation thereof on the insert-installation seats prepared on both sides of the milling cutter body.

    摘要： Provided is a coating layer for cutting tools, as a hard coating layer stacked and formed in the sequence of a TiN layer, a TiCN layer, a bonding layer, an alumina (Al2O3) layer, and a cover layer from the bottom by using a chemical vapor deposition (CVD) method on a parent material, able to improve cutting performance, because surface residual stress of the coating layer may be maintained in a compressive stress state by adjusting a composition of the cover layer without using a separate additional process, such as a blasting operation, or a mixed process of CVD and physical vapor deposition (PVD), and simultaneously the cover layer may also be used as a wear-resistant layer.The coating layer according to present invention is formed on a surface of a parent material by using a CVD method, in which the coating layer includes an alumina layer formed of an α-phase, disposed on the parent material and composed of a composite structure having a columnar crystal structure and an equiaxed crystal structure mixed therein, and a cover layer formed of AlxTiySizCrwN (herein, x+y+z+w=1, x≧0.75, y≧0.2, 0≦z≦0.06, 0≦w≦0.08) and disposed on the alumina layer.
