Cutting tools are used for cutting in mechanical manufacturing. Most of them are machine tools, but also hand tools. Since the cutting tools used in mechanical manufacturing are basically used to cut metal materials, the term "tool" is generally understood as a metal cutting tool. The cutting tools used to cut wood are called woodworking tools.

刀具按工件加工表面的形式可分為五類：

Tools can be divided into five categories according to the form of workpiece surface processing:

1、 加工各種外表面的刀具、包括車刀、刨刀、銑刀、外表面拉刀和銼刀等.

1. Processing all kinds of external surface cutters, including turning tools, planers, milling tools, external surface Broaches and files, etc.

2、 孔加工刀具，包括鉆頭、擴孔鉆、鏜刀、鉸刀和內表面拉刀等.

2. Hole processing tools, including drill, reamer, boring cutter, reamer and internal broach, etc.

3、 螺紋加工刀具，包括絲錐、板牙、自動開合螺紋切頭、螺紋車刀和螺紋銑刀等.

3. Thread processing tools, including tap, die, automatic opening and closing thread cutting head, thread turning tool, thread milling tool, etc.

4、齒輪加工刀具，包括滾刀、插齒刀、剃齒刀、錐齒輪加工刀具等.

4. Gear cutting tools, including hobs, gear shapers, shaving cutters, bevel gear cutting tools, etc.

5、 切斷刀具，包括鑲齒圓鋸片、帶鋸、弓鋸、切斷車刀和鋸片銑刀等等，此外，還有組合刀具.按切削運動方式和相應的刀刃形狀，刀具又可分為三大類：

5. Cutting tools, including insert circular saw blade, band saw, bow saw, cutting lathe tool and saw milling cutter, etc. in addition, there are combined tools. According to the cutting movement mode and corresponding blade shape, the tools can be divided into three categories:

一、 通用刀具，如車刀、刨刀、銑刀(不包括成形的車刀、成形刨刀和成形銑刀)、鏜刀、鉆頭、擴孔鉆、鉸刀和鋸等，

I. General cutters, such as turning tools, planers, milling cutters (excluding formed turning tools, forming planers and forming milling cutters), boring cutters, drills, reamers, reamers and saws, etc.

二、 成形刀具，這類刀具的刀刃具有與被加工工件斷面相同或接近相同的形狀，如成形車刀、成形刨刀、成形銑刀、拉刀、圓錐鉸刀和各種螺紋加工刀具等.

2. Forming cutter. The cutting edge of this kind of cutter has the same or nearly the same shape as the cross section of the workpiece to be processed, such as forming turning tool, forming planer, forming milling tool, broach, taper reamer and various thread processing tools.

三、展成刀具是用展成法加工齒輪的齒面或類似的工件，如滾刀、插齒刀、剃齒刀、錐齒輪刨刀和錐齒輪銑刀盤等。結構各種刀具的結構都由裝夾部分和工作部分組成。整體結構刀具的裝夾部分和工作部分都做在刀體上，鑲齒結構刀具的工作部分(刀齒或刀片)則鑲裝在刀體上.

3. The generating tool is to use the generating method to process the gear tooth surface or similar workpiece, such as hob, gear shaper, shaving cutter, bevel gear planer, bevel gear milling cutter disc, etc. The structure of all kinds of cutting tools is composed of clamping part and working part. The clamping part and the working part of the integral structure cutter are all made on the cutter body, and the working part (cutter tooth or blade) of the gear inserted structure cutter is inlaid on the cutter body.

刀具的裝夾部分有帶孔和帶柄兩類。帶孔刀具依靠內孔套裝在機床的主軸或心軸上，借助軸向鍵或端面鍵傳遞扭轉力矩，如圓柱形銑刀、套式面銑刀等.高效、便捷、專業、完整提供高品質高精密進口模具機械、工具、刀具和材料等工模機械用品.

There are two kinds of clamping parts of the cutter, one is with hole and the other is with handle. The tool with hole is installed on the spindle or spindle of the machine tool by the inner hole, and the torsion moment is transmitted by the axial key or end key, such as cylindrical milling cutter and sleeve type face milling cutter. It is efficient, convenient, professional and complete to provide high-quality and high-precision imported mold machinery, tools, cutters and materials.
