摘要： Disclosed is a cutting tool, including: a cutting edge including a coating from a rake face to a flank face, and has a relief angle of not less than 15 degrees, a material of the coating having a higher wear resistance than a base material of the cutting edge, and during cutting of a work, an edge of the coating on the rake face at a top of the cutting edge is worn by friction with the work; with a progress of a wear inward in a radial direction, an edge of the coating on the flank face at the top of the cutting edge is removed by friction with the work to expose the base material thereunder; and the exposed base material is worn by friction with the work to retract the flank face inward in the radial direction.
摘要翻译：公开了一种切削工具，包括：切削刃，其包括从前刀面到后刀面的涂层，并且具有不小于15度的倾斜角度，所述涂层的材料具有比基体材料更高的耐磨性切割边缘，并且在切割工件期间，切削刃顶部的前刀面上的涂层的边缘与工件摩擦磨损; 随着在径向方向向内的磨损进展，通过与工件的摩擦而去除切削刃顶部的侧面上的涂层的边缘以暴露其下的基底材料; 并且暴露的基底材料通过与工件的摩擦而磨损，以使其沿径向向内缩回。

摘要： The object of the invention is to provide a sleeve removal tool that is able to easily remove a sleeve from a tap without damaging the sleeve. The sleeve removal tool has a first fastening member and a second fastening member. The first fastening member has a first contact surface and inner screw section, and is formed in a cylindrical shape. The first contact surface comes in contact with the flange of the sleeve all around one ring shaped surface. An inner screw section is provided such that it protrudes in the axial direction from the first contact surface. The second fastening member has a second contact surface and outer screw section, and is formed in a cylindrical shape. The first contact surface comes in contact all around the other ring shaped surface of the flange.

摘要： The object of the invention is to provide a hand drill that capable of suppressing delamination that occurs when drilling holes in an object, as well as being more compact. The hand drill has a base member, a damper, a drill and drill blade. The base member has a contact surface that comes in contact with an object being drilled, and a drill bushing. The damper comprises a piston rod and a cylinder, and extends or contracts in its own axial direction. The tip end section of the piston rod is fastened to the base member. The drill is fastened to the cylinder and displaces together with the cylinder. The drill blade is installed in the drill so that it is parallel to the axial direction of the damper. When the damper is in the extended state, the tip end of the drill blade is located at the tip end of the drill bushing.
摘要翻译：本发明的目的是提供一种手钻，其能够抑制在物体中钻孔时发生的分层，并且更紧凑。手钻具有基座部件，阻尼器，钻头和钻刀。基座构件具有与要被钻孔的物体接触的接触表面和钻套筒。阻尼器包括活塞杆和气缸，并且在其自身的轴向方向上延伸或收缩。活塞杆的前端部固定在基座部件上。钻头固定在缸体上，与气缸一起移动。钻刀安装在钻头中，使其平行于阻尼器的轴向。当阻尼器处于伸展状态时，钻头的尖端位于钻套筒的末端。
