| Classification Dimension | Main Type | English Name | Characteristics & Core Applications |
|---|---|---|---|
| By Drive Method | Hand Tap | Hand Tap | Operated manually, typically used with tap wrenches or manual tapping; common in repair work or single-piece production. |
| Taper Tap | Long chamfer (approx. 6-8 threads); provides smooth entry and distributes Cutting force; suitable for difficult-to-machine materials or as a starting tap. | ||
| Plug Tap | Medium chamfer (approx. 3-5 threads); the most commonly used type; suitable for both through-holes and blind holes. | ||
| Bottoming Tap | Very short chamfer (approx. 1-1.5 threads); used when threads need to be cut all the way to the bottom of a blind hole, but cannot be used for starting threads. | ||
| Machine Tap | Machine Tap | Used on machine tools (e.g., tapping machines, machining centers); demands higher precision and longer tool life. | |
| By Machining Principle | Cutting Tap | Cutting Tap | Forms threads by removing material through cutting; the most common type. |
| Forming Tap / Roll Tap | Forming Tap / Roll Tap | Forms threads by displacing material through plastic deformation; produces no chips, resulting in stronger threads. Suitable for ductile materials (e.g., aluminum alloys, low-carbon steel). | |
| By Flute Shape | Straight Flute Tap | Straight Flute Tap | Most versatile, simple structure, easy to manufacture. Suitable for materials that produce powdery or short chips; can be used for both through-holes and blind holes. |
| Spiral Flute Tap | Spiral Flute Tap | Excellent chip evacuation; chips are pushed backward (toward the shank), making it especially suitable for blind holes. The helix angle is selected based on material: smaller angles (~30°) for ferrous metals, larger angles (~45°) for non-ferrous metals to maintain sharpness. | |
| Spiral Point Tap / Gun Tap | Spiral Point Tap / Gun Tap | Features a slotted chamfer that pushes chips forward (in the tapping direction), making it ideal for through-holes. Has a larger core diameter for greater strength. | |
| By Application Scenario | Through-hole Tap | Through-hole Tap | Specifically refers to taps used for through-holes, such as the Spiral Point Tap. |
| Blind-hole Tap | Blind-hole Tap | Specifically refers to taps used for blind holes, such as the Spiral Flute Tap. | |
| Nut Tap | Nut Tap | A longer tap specially designed for cutting threads in nuts on nut-threading machines. | |
| Pipe Tap | Pipe Tap | Used for machining pipe threads. | |
Special | Trapezoidal tap | Trapezoidal tap | A specialized cutting tool designed for machining internal trapezoidal threads. Its core function is to efficiently cut trapezoidal threaded holes in workpieces, primarily used in applications requiring transmission of power, motion, and displacement in mechanical systems,mostly supplied in sets (2 to 5 pieces),typically used for threads with nominal diameters below 50mm and pitches below 6mm (most commonly for sizes up to Tr30×6) |
