　　Tool class

　　Whatever tool you choose, it is important to know the following:

　　What is the material? What machine are you using? Finish or rough finish? Is there any drawing requirement? What is the compression mode? How much is the knife square? Type of blade?

　　I. External turning tool:

　　What is the required principal deflection Angle of the tool? Are there any drawing requirements? What is the material being processed? Are there any hardness requirements?

　　Ii. Turning tool with inner hole:

　　What's the diameter? How deep is the hole? What is the inner diameter of the tool sleeve? Does the inner hole interfere?

　　3. Grooving knife:

　　How deep do you want to cut? What is the width of the slot? Is the end groove external round groove or internal hole groove knife? What are the maximum and minimum machining diameters? (Special question on end groove knife)

　　Iv. Cutting Knife:

　　What is the diameter of the cut? What is the width of the slot?

　　5. Thread turning tool:

　　Front and back hand of thread turning tool? External thread or internal thread? Metric system or Imperial system? What is the pitch?

　　Cutter holder class

　　Milling cutter type :(take machining center as an example)

　　2. Type of clamping milling cutter:

　　How big is the milling cutter required to be clamped? A: Strong, standard or high speed?

　　What is the type of taper shank? How big is the threaded hole?

　　3. Clamping wire tapping:

　　Do you want rigid or flexible tapping? What size tap?

　　4. Type of clamping face milling cutter disks:

　　What is the diameter of the knife disc? How big is the inner circle of the knife plate? Metric or Imperial hole? Is there a length requirement?

　　5. Boring knife:

　　A. coarse boring cutter

　　Do you want it modular or integral? What is the required range of processing? Length of processing? Is extension rod required?

　　B. fine boring cutter

　　Do you want it modular or integral? What is the machining accuracy? What is the length of the process? Is it necessary to add a long rod to increase the machining range?

　　6. The knife instrument:

　　Do you want a table or a digital display, or a projection? What is the range of measurement? What is the measurement accuracy?

　　The cutting tool class

　　one Cutter:

　　1. Integral milling cutter

　　Do you want high speed steel or cemented carbide end mills? What is the hardness of the process? Small length requirement? How many blade? Ball head or flat head? What's the degree of the handle? What are the threads? What kind of coating? What is the helix Angle?

　　2. Blade type milling cutter

　　1) Spindle type milling cutter

　　What is the diameter? Is there any requirement on the Angle of the blade? How long is the processing length?

　　2) Cutter plate;

　　What's the diameter? What is the Angle of the blade? Finish or rough finish? Is there any requirement for tool cleaning?

　　two Bit:

　　1) Straight shank drill

　　Is the bit required to be high speed rigid or cemented carbide? What is the machining diameter? What is the depth of processing? Is there any requirement for blade?

　　2) Taper shank drill bit

　　What size is the original set of the cutter? What is the machining diameter? What is the required depth of processing? Is there any requirement for blade?

　　3. Tap class:

　　1) Screw tap

　　Do you want a left-handed or a right-handed tap? What is the thread size required? Is it metric or English? What is the machining accuracy level? What is the material? What country's standard?

　　2) Straight slot tapping

　　What is the material? Is it a hand attack or a machine attack?

　　Four. Chamfering knife:

　　What is the range of chamfering? What's the Angle?

　　Five. Reamer:

　　1) Straight shank reamer
