Round Punch No. 6, Ø23.5 mm | Ref. P6R2350

REF: 105P0042

Impact Resistance and Performance in Intensive Punching Operations

The Ø23.5 mm round punch, model P6R2350, 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 absorb intense shearing loads without undergoing deformation or developing nicks along the cutting edge.

Technical Advantages

Universal Standard No. 6: A standard geometry fully compatible with the hydraulic punching machines and universal 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 Ø23.5 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 service life of the tool.

Technical Product Specifications

Product Reference: P6R2350.
Material Compatibility: Structural steel plate (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 Ø23.5 mm punch, the selected No. 6 die must have the appropriate clearance based on the sheet thickness ( $Clearance = 15-20\%$ of the sheet thickness for steel).
Recommended Maintenance and Use: Keep the punch lubricated with cutting oil to reduce friction during extraction (stripping), and periodically check its alignment with the die to prevent off-center rubbing.
