1, according to the tool material classification

High speed steel: high bending strength and impact toughness, good machinability.

Hard alloy: using chemical vapor deposition method coated titanium carbide, titanium nitride, alumina hard layer or composite hard layer, so that the tool wear is low, long service life.

2, according to the cutting tool movement classification

General tool: commonly used turning tool, planer, milling cutter, boring cutter, drill, reaming drill, reamer and saw, etc.

Forming tool: commonly used forming turning tool, forming planer, forming milling cutter, broach, conical reamer and a variety of thread processing tools.

Development tool: commonly used hob, gear shaper, shaving knife, bevel gear planer and bevel gear milling cutter plate.

3, according to the tool work part classification

Integral: the cutting edge is made on the cutting body.

Welding: brazing the blade to the steel body.

Mechanical clamping type: the blade is clamped on the cutter body, or the brazed cutter head is clamped on the cutter body
