Impact Resistance and Performance in Intensive Punching Operations

The P6R2700 round punch (Ø27.0 mm) is precision-ground to ensure optimal centering within the punch holder head of universal punching machines (such as those from Geka, Peddinghaus, Mubea, Sunrise, and other brands compatible with the No. 6 standard). Its head and treated shank are designed to absorb intense shearing loads without deforming or developing nicks along the cutting edge.

Technical Advantages

• Universal Standard No. 6: A standard geometry fully compatible with the hydraulic punching and shearing machines most widely used in the industrial sector.

• High-Alloy Tool Steel: Offers excellent toughness, preventing micro-cracking or premature breakage under high-tonnage impacts.

• High-Precision Sharpening and Grinding: Produces clean Ø27.0 mm holes with minimal shear-edge deformation and very little burr formation.

• High Stress-Absorption Capacity: Features differential heat treatment—applied separately to the impact zone at the head and the cutting edge—to extend the tool's service life.

 Technical Product Specifications

Product Reference: P6R2700.

• Material Compatibility: Structural steel sheet (S235, S275, S355), stainless steel (requires appropriate die clearance), aluminum, brass, and metal flat bars.
• Die Clearance Recommendations: To achieve a clean cut and preserve the cutting edge of this Ø27.0 mm punch, the selected No. 6 die (such as Ref. M6R2770) must have the proper clearance based on the sheet thickness (Clearance = 15–20% of the sheet thickness for steel).
• Maintenance and Recommended Use: Keep the [tool] lubricated. ...apply cutting oil to the punch to reduce friction during stripping, and periodically check its alignment with the die to prevent off-center rubbing.
