What is taps materiasl always Taps adopted for different work
There always many materials for taps production such as HSS, HSS Co, HSSE Co8%, HSSE V3,PM-HSSE V3,PM-HSS Co,SPM,VHM, VHM, VHM-ULTRA
how should we choose the right taps with different materials to achieve best performance ? below is the commonly materials list for your choose:
| Abbreviations | Type | Application | Description | |
| HSS | Conventional high speed steel | Standard tool material for most common applications | Used for the manufacturing of cutting tools such as twist drills, end mills and taps. Yields consistent hardness levels following heat treatment providing for a reputable tool life. | |
| HSS Co | 5% cobalt grade of high speed steel | High-heat resistance, especially suited for roughing or when coolant insufficient | Cobalt alloyed, tungsten-molybdenum high speed steel possessing high hardness, excellent cutting properties, high-red hardness and good toughness. | |
| HSSE Co8% | 8% cobalt grade of high speed steel | Increased heat resistance & hardness, suitable for difficult-to-machine materials | Available for applications that require a strong resistance to softening at elevated cutting temperatures. The ability of the steel to maintain its “red-hot hardness” is provided by the addition of cobalt. The high hot hardness is required for machining difficult materials such as nickel-base, titanium and highly alloyed steel. | |
| HSSE V3 | Premium grade of high speed steel | Wide range of machine taps. | Vanadium grade gives high wear resistance and toughness for most tapping applications. | |
| PM-HSSE V3 | Powdered metallurgy - vanadium grade of high speed steel | Materials with hardness up to 40HRc Difficult to machine materials eg. stainless steels. | PM-HSS V3 for higher performance tools, incorporates very fine and uniform grain structure allowing a high hardness to be achieved, whilst maintaining good toughness. | |
| PM-HSS Co | Powdered metallurgy - 8% Cobalt grade of high speed steel |
Materials with hardness up to 45HRc | The addition of cobalt provides this material with the ability to maintain its strength and hardness level when exposed to extremely high cutting temperatures. This makes PM-HSS Co suitable for heavy duty tapping, in materials such as high alloyed steels to non-ferrous metals like Ni-base alloys & Ti-alloys. | |
| SPM | Powdered metallurgy - 11% Cobalt grade of high speed steel | Special applications, requiring very high edge hardness. Cutting tools with the appropriate geometry can be applied to workpiece materials with hardness up to 55HRc |
An excellent bridge material between high speed steel and carbide. SPM offers very high red hardness, wear resistance and the highest compressive strength of any high speed steel. | |
| VHM | Sub-micron grade of solid Carbide (ISO K15-K30) |
Tapping hardened steel | Ultra fine grain type (0.8µm) with maximum toughness & high hardness, therefore especially recommended for rotating tools to machine hardened parts. | |
| VHM | Sub-micron grade of solid Carbide (ISO K40) |
Sutton standard grade for endmills & drills | Ultra fine grain type (0.6µm) offers the ideal combination of hardness & toughness for high performance drilling & general milling applications | |
| VHM-ULTRA | Sub-micron grade of solid Carbide (ISO K40-K50) |
High performance grade for endmills | Ultra fine grain type (0.5µm) offers the best wear resistance for high performance milling applications. | |
