Round and Hex Die
| Type | Size Range | Features | Typical Applications |
|---|---|---|---|
| Round Die (Circular Die) | M0.25 ~ M68mm | Most widely used; mounted in a die stock for hand use or on machines. Divided into solid type (good rigidity, suitable for heavy Cutting) and adjustable type (with adjustment slots for fine-tuning thread pitch diameter to compensate for wear or correct dimensions). | General thread cutting, such as on bolts and threaded rods. |
| Square/Hexagon Die | No national standard; sizes vary | Square or hexagonal shape, driven directly by a wrench without a die stock. Less common in the market; sometimes modified from round dies. | Tight spaces where a standard die stock cannot fit, such as on machine anchor bolts. |
| Pipe Die | Corresponding pipe thread sizes | Specifically designed for pipe thread machining, often of segmented construction for easy mounting. | Used with pipe threading machines (power threaders) for cutting threads on water pipes and gas pipes. |
| Category | Thread Type | Thread Angle | Common Applications |
|---|---|---|---|
| Metric Die | Metric standard thread (M) | 60° | Mechanical fasteners, e.g., M10×1.5 bolts. |
| BSPT Die | British Standard Pipe taper thread | 55° | Water and gas pipelines; commonly used in the UK and Commonwealth countries. |
| NPT Die | National Pipe Taper thread (US standard) | 60° | US standard pipe threads; used in petroleum and chemical pipelines. |
| Material | Hardness & Wear Resistance | Suitable Workpiece Materials | Typical Applications |
|---|---|---|---|
| Tool Steel (Alloy Tool Steel) | Moderate | Mild steel, copper, aluminum, and other conventional materials | General machining, maintenance, DIY |
| High-Speed Steel (HSS / HSSE) | High, with good heat resistance | Stainless steel, heat-resistant steels, and other difficult-to-machine materials | Professional machining, batch production |
| Carbide (Cemented Carbide) | Extremely high, with long tool life | Hardened steel, cast iron, and other hard materials | High-speed cutting, high-volume/high-precision production |
| Application Method | Tools Used | Features | Typical Settings |
|---|---|---|---|
| Hand Thread Cutting | Die stock + round die | Flexible operation, suitable for small batches; requires reverse rotation every few turns for chip breaking; use with cutting oil. | Repair workshops, on-site installation, DIY workshops |
| Machine Thread Cutting | Lathe/drilling machine + die holder | Higher efficiency than hand cutting, with controllable precision; suitable for medium batch production. | Machine shops, batch part production |
| Pipe Threading (Power Threader) | Power threader + pipe die | Fast and labor-saving; specifically designed for pipe-end thread cutting; a core tool in pipeline installation. | Pipeline installation, construction sites, plumbing repair |
| Thread Repair / Cleaning | Die (used as a chaser) | Used to clean or repair damaged external threads; also called a "thread restoring die." | Equipment maintenance, reconditioning of old parts |
