Nº8 Round Ø14.5 H.0.7 mm | Ref. M8R1520

REF: 105M0131

Clean Cut, Minimal Burr, and Maximum Wear Resistance

The M8R1520 round die is designed to withstand high operating pressures in punching machines from leading brands. Its nominal diameter of Ø14.5 mm—designed for 14.5 mm punches (commonly used for M14 screw clearance holes)—combined with a 0.7 mm die clearance, ensures optimal material shearing, reduces burr formation, and minimizes punch stress during penetration.

Technical Advantages

Standard Type No. 8 Geometry: Highly compatible with standard die holders from leading punch-shear machines on the market.
0.7 mm Cutting Clearance (H.0.7): Clearance optimized for appropriate sheet thicknesses, preventing punch binding and ensuring smooth slug ejection.
Heat-Treated Alloy Steel: High surface hardness to resist abrasion and chipping during repetitive punching cycles.
High-Precision Finish: Ground diameter of Ø14.5 mm nominal (Ø15.2 mm actual, including cutting clearance) to ensure perfectly cylindrical and accurately sized holes.

Technical Specifications

Product Reference: M8R1520.
Machine Compatibility: Hydraulic punching machines, combined ironworkers (Geka, Peddinghaus, Nargesa, etc.), and punching presses with No. 8 die holders.
Material Application: Punching of carbon steel sheet, stainless steel, aluminum, flat bars, and structural profiles (IPN, UPN, angles).
Maintenance and Lubrication: Keep the punch-die axis aligned and apply cutting oil/grease to extend the life of the die's cutting edge.
