Fierte’s Singer-Sided Acute Punch is a specialized press brake punch engineered for precision sheet metal bending, particularly for applications requiring sharp, accurate angles. As a core product in our line of sheet metal processing tools, this acute punch combines advanced design, premium materials, and meticulous manufacturing to deliver exceptional performance in demanding industrial settings. Whether you’re fabricating precision components for electronics, automotive parts, or architectural hardware, the Singer-Sided Acute Punch ensures clean, consistent bends with minimal material waste.
With decades of expertise in bending tools and crowning tables, Fierte is committed to producing high-quality punches and dies for all types of press brakes. Our Singer-Sided Acute Punch is crafted from top-grade 42CrMo4/42CrMo/C45 steel, undergoes rigorous heat treatment, and features versatile surface finishes—all designed to meet the needs of modern manufacturing. Backed by our in-house R&D team and technical support, this punch offers compatibility with a wide range of press brake models, making it a flexible, reliable choice for manufacturers seeking precision and efficiency.
The Singer-Sided Acute Punch features a sharp, precisely ground acute angle that enables clean, accurate bends in sheet metal. This design is ideal for applications requiring tight angles (e.g., 30°, 45°, 60°) and smooth, burr-free edges. Whether working with mild steel, aluminum, or stainless steel, the punch’s acute profile ensures consistent results, reducing rework and improving production efficiency.
Manufactured from 42CrMo4/42CrMo/C45 steel—a selection of premium alloys renowned for their strength, toughness, and wear resistance—this acute punch is built to withstand the rigors of high-volume bending operations. The high-quality steel ensures that the punch maintains its sharpness and structural integrity over thousands of cycles, delivering long-lasting performance.
Each Singer-Sided Acute Punch undergoes whole body heat treatment with a hardness rating of HRC48-50. This process ensures uniform hardness across the entire punch, preventing localized wear, chipping, or deformation. The optimal hardness balance allows the punch to handle high-pressure bending while remaining flexible enough to avoid brittle fracture—critical for precision applications.
To enhance durability and performance, we offer three surface treatment options: blackening, sandblasting, and sandblasting + blackening. Blackening provides a corrosion-resistant finish for indoor use, sandblasting reduces material adhesion during bending, and the combined treatment offers maximum protection against rust, wear, and friction—ideal for harsh or high-moisture environments.
The Singer-Sided Acute Punch is designed to fit most leading press brake models, including Amada/Promecam, Trumpf/Wila, Bystronic/Beyeler, LVD, and Gasparini. This wide compatibility eliminates the need for custom adapters or tool replacements when switching between press brakes, making it a cost-effective solution for diverse manufacturing setups.
Precision grinding is a key step in the manufacturing process of our acute punch. Each punch is ground to tight tolerances, ensuring that the acute angle remains consistent and the surface is smooth. This precision translates to accurate bends, reduced material waste, and faster production speeds—helping you meet tight project deadlines without compromising quality.
The combination of premium steel, heat treatment, and surface finishing ensures that the Singer-Sided Acute Punch offers exceptional wear resistance. Even when bending abrasive materials (e.g., stainless steel), the punch maintains its sharpness and performance, reducing the frequency of tool replacements and lowering overall production costs.

Fierte's customization service for the Singer-Sided Acute Punch is tailored to meet the unique needs of your sheet metal bending projects. Whether you require a specific angle, modified dimensions, or specialized features, our R&D team and technical department are dedicated to delivering personalized solutions.
We offer custom acute angle configurations to match your project requirements. Whether you need a 20° punch for delicate electronics components or a 70° punch for heavy-duty brackets, our engineers design and manufacture the punch to your exact specifications. The custom angle is precision-ground to ensure accuracy and consistency.
If standard punch dimensions don’t fit your press brake or application, we can modify the length, diameter, or shank design of the Singer-Sided Acute Punch. Our team works with you to understand your press brake’s specifications and bending needs, ensuring that the custom punch integrates seamlessly into your production line.
For extreme applications (e.g., bending high-strength steel or abrasive materials), we offer specialized material upgrades and surface treatments. Our technical team can recommend the optimal steel grade and surface finish to enhance wear resistance, corrosion protection, and overall performance—ensuring that your custom punch meets the demands of your specific application.
We provide comprehensive technical support throughout the customization process, from initial design to final delivery. Our team can also arrange on-site inspection and guidance to verify the punch’s performance and ensure proper installation. We are committed to helping you achieve the best possible results with your custom Singer-Sided Acute Punch.
The Singer-Sided Acute Punch is ideal for applications requiring sharp, accurate acute angles—such as fabricating electronic enclosures, automotive brackets, architectural trim, and precision hardware. It excels in bending thin to medium-gauge sheet metal (mild steel, aluminum, stainless steel) where clean, burr-free edges and consistent angles are critical.
Yes! We offer full angle customization for the Singer-Sided Acute Punch. Whether you need a 30°, 45°, 60°, or any other acute angle (within practical manufacturing limits), our R&D team will design and manufacture the punch to your exact requirements. Simply share your angle specifications and application details, and we’ll deliver a tailored solution.
The HRC48-50 hardness rating is optimal for press brake punches: it provides sufficient hardness to withstand high-pressure bending and resist wear, while remaining flexible enough to avoid brittle fracture. This balance ensures that the Singer-Sided Acute Punch maintains its sharpness and structural integrity over long service lives, even in high-volume production environments.
