0.7 mm Technical Clearance: Cutting Geometry and Sheet Thickness

The 0.7 mm clearance in a Ø24.5 mm die is optimally dimensioned for working with carbon steel sheet thicknesses of approximately 3.5 mm to 4.5 mm (applying the technical rule of 15–20% of the material thickness). Proper clearance prevents premature wear caused by friction between the punch and the die wall, drastically reduces the tonnage required by the machine, and avoids the formation of excessive burrs or conical deformation of the punched hole.

Technical Advantages

• Universal Standard No. 6: Fully compatible with die holders for the most common mechanical and hydraulic punching machines on the market (Geka, Peddinghaus, Mubea, Sunrise, etc.).

• High-Toughness, High-Hardness Tool Steel: Resists continuous lateral compression and impact forces without deformation at the die opening.

• Slug Clearance and Relief: Precision-ground lower channel with a tapered relief to ensure the punched-out material (slug) falls away smoothly and quickly, without jamming.

• Precision Fit and Centering: Precision-ground seat ensures ideal alignment with the punch, preventing breakage caused by misalignment.

Product Technical Specifications

• Product Reference: M6R2520.

• Material Compatibility: Structural steel sheet (S235, S275, S355), stainless steel, galvanized sheet, and aluminum alloys.

• Clearance Selection: For thinner sheet metal (e.g., 1.5–2 mm), dies with smaller clearance (0.2–0.4 mm) are recommended; For thicknesses of 3.5 to 4.5 mm, the 0.7 mm clearance of die Ref. M6R2520 is the ideal configuration.

• Recommended Maintenance: Keep the die housing and base free of metal shavings and debris before securing the locking set screw, ensuring that the top surface remains flat and parallel.
