HSS punches are metalworking tools used for creating holes or indentations in materials like metal, plastic, and paper. They are made of high-speed steel (HSS), a specialized steel alloy known for its hardness, durability, and resistance to wear, making them ideal for high-pressure applications.

What they are:

HSS punches are a type of tool used for punching or stamping, which involves creating holes or shapes by forcing a punch through a material. 

Material:

HSS punches are typically made from high-speed steel (HSS), a tool steel alloy that retains its hardness and strength even at high temperatures.

Uses:

HSS punches are used in various industries for tasks like:

Creating holes: Punching out holes in metal sheets or other materials. 

Forming shapes: Creating indentations or impressions for further processing. 

Driving fasteners: Inserting nails, dowels, or pins. 

Decorative purposes: Creating patterns or images. 

Types:

There are different types of HSS punches, including:

Step Punches: Used for creating steps or tiered holes. 

Round Punches: Standard punches with a round tip. 

Pin Punches: Used for driving out pins or rivets.
