What is a tap?
A tap is a cutting tool used to machine internal threads inside a pre-drilled hole. It forms threads by cutting or forming material, allowing screws or bolts to be securely fastened in metal or other materials.
What are the common materials used for taps?
The most common materials for industrial thread taps include:
HSS (High Speed Steel): M2
HSSE (Cobalt HSS): M35 (5% Co), M42 (8% Co)
Powder Metallurgy HSS (PM-HSS): ASP2030, ASP2052
Tungsten Carbide (HM): WC 90% | Co 10% | Grain size 0.5–0.8 μm
Each material offers different performance in terms of wear resistance, toughness, and cutting speed.
What materials does Vohirl Metal commonly use for its taps?
At Vohirl Metal, the most commonly used materials for our taps are M2, M35, and ASP2030, which cover over 95% of industrial tapping applications.
Materials such as M42 and ASP2052 are selected for specific working conditions that require higher heat resistance or tool life.
How should customers choose the right tap material?
Choosing the correct tap material depends on the workpiece material, cutting speed, and production volume.
