Your Trusted HSS Punch Manufacturer in China
As a professional supplier and manufacturer of HSS punches in China, every HSS punch is manufactured through CNC machining, precision grinding, vacuum heat treatment, and 100% dimension inspection.
We use quality-tested high-speed steel (HSS) for the punch, as it can retain its hardness even at high temperatures. All the materials come from reliable and trusted vendors. All the punches are made by highly advanced machines.
It is widely used for punching, marking, ejecting moulds, piercing, and pressing tools. Multi-purpose mould and die industrial applications. And creating holes for steel, copper, paper, plastic, and so on.
Customize of our HSS Punches
Creates holes of different diameters in a single operation, also known as an A-Punch.
Used for custom hole designs, including hexagonal, octagonal, and other unique shapes.
The most common type among HSS punches, used for circular holes. Also known as a T-Punch.
Creates pilot holes to guide a second punch through the material, ensuring precision.

Why Choose HSS Punch?
Compared to high-carbon steel punch pins, high-speed steel maintains its hardened state (hardness) at higher temperatures, offers greater stability during rapid cutting processes, experiences less wear than high-carbon steel, and consequently ensures longer service life and higher precision.
HSS punch is recommended when:
- Impact resistance is required
- Complex punch shapes
- Medium to high production
- Budget control
For highly abrasive materials and in high-volume production environments, cemented carbide punches may be the better choice.
Applications for The HSS Punch
As the most widely used HSS punch globally, it is used for terminal stamping, sheet metal, connectors, piercing, coining, cold forming, and progressive die, it is also widely used. Its high hardness, excellent wear resistance, and thermal stability ensure a long service life and precise performance.
A customer previously used the normal punches, the punches broke every 2-3 days, after optimized HTX optimized HSS material & precision grinding, the punch life increased by 180%, and downtime was reduced by 32%. This is not a theoretical estimate, but actual feedback we’ve received from our clients. Please see the full case study.
Advantage of Our HSS Punch
HTX ejector pins deliver excellent wear resistance and stable hardness through vacuum nitriding, with a hardened surface supported by a tough, impact-resistant core. Each pin is precision ground for a smooth surface finish and consistent concentricity, ensuring reliable ejection and extended service life in high-cycle molds.

HSS punches are better suited for medium-hardness materials and conventional stamping operations. Compared to standard tool steel, HSS offers a superior balance between wear resistance and toughness, making it ideal for medium-to-high-speed stamping and mass production scenarios. However, it should not be used to pursue the absolute maximum service life of the punch.
The service life depends on the thickness and hardness of the stamped material. It is certain that the service life of an HSS punch is 2-3 times longer than that of ordinary tool steel. However, using an HSS punch reduces the frequency of punch pin replacement, thereby improving production efficiency.
For stability and cost-effectiveness, choose an HSS punch.
For high hardness and extended service life, choose a carbide punch.
Most customers typically use both types in combination across different workstations.
Yes, HSS Punch is ideal for those prioritizing cost-effectiveness and reliability. We can fully customize the shape, diameter, and head profile according to your drawings, enabling better cost control.
HSS punches are not suitable for use in ultra-high-speed stamping operations, when stamping extremely hard materials, or when the product aperture is very small, the punch pin requires a long service life, and long-term maintenance is not feasible.
