Key Blank - for 64179

Key Blank – 64179

The Key Blank 64179 is a precision‑cut steel key blank designed to fit the Draper 30mm Laminated Steel Padlock (Model 64179). It serves as the foundational component for creating custom keys that operate securely and reliably on this padlock. The blank’s geometry, dimensions, and material composition are engineered to match the lock’s internal pinning system, ensuring a perfect fit and smooth operation.

Material Composition

The key blank is manufactured from high‑strength steel alloy, chosen for its durability and resistance to wear. The alloy undergoes a controlled heat treatment process that enhances hardness while maintaining sufficient ductility for machining. This combination allows the blank to withstand repeated cutting, filing, and bending without compromising structural integrity.

Dimensional Specifications

• Length: 30 mm – matching the padlock’s shackle diameter.
• Width: Standard key blank width for 64179, typically around 6–8 mm depending on manufacturer tolerances.
• Thickness: Approximately 1.5 mm, providing a balance between rigidity and machinability.
• Keyway Profile: The blank features the exact keyway profile required for the padlock’s internal pin stack, including precise cut depths and angles.

Keyway Geometry

The keyway is engineered to accommodate the padlock’s unique pinning arrangement. It includes:

• A series of notches that correspond to the lock’s pins.
Cutting angles that match the lock’s internal geometry, ensuring a snug fit. key blade shape that aligns with the padlock’s cylinder, allowing smooth insertion and rotation.

Manufacturing Process

The blank is produced through a multi‑stage process:

1. Cutting: CNC machining cuts the raw steel to the exact dimensions of the 64179 keyway.
2. Heat Treatment: The blank undergoes annealing and quenching to achieve optimal hardness.
3. Surface Finishing: A fine polishing step removes burrs and ensures a smooth surface for subsequent key cutting.
4. Quality Inspection: Each blank is inspected against dimensional tolerances and tested in a prototype lock to confirm functionality.

Applications

The Key Blank 64179 is ideal for:

• Custom Key Production: Locksmiths can cut personalized keys for clients who own the Draper 30mm Laminated Steel Padlock.
• Security Audits: Security professionals may use the blank to create duplicate keys during facility audits, ensuring that all locks are accounted for.
• Training and Education: Institutions teaching lock mechanics can employ the blank as a hands‑on tool for students learning key cutting techniques.

Compatibility

The blank is specifically engineered for the Draper 30mm Laminated Steel Padlock (Model 64179). It matches the lock’s:

• Pin Stack Configuration – ensuring that each cut on the key aligns with a pin.
• Shackle Diameter – guaranteeing that the key fits without excessive clearance.
• Internal Cylinder Geometry – allowing smooth rotation once inserted.

Key Cutting Instructions

To produce a functional key from the blank, follow these steps:

1. Marking: Use a key cutting template or digital key design software to determine cut depths.
2. Cutting: Employ a precision key saw or CNC key cutter to remove material according to the template.
3. Bending: Carefully bend the key blade to match the lock’s keyway curvature, ensuring no sharp edges remain.
4. Polishing: Smooth any burrs with a fine file or sandpaper to prevent damage during insertion.
5. Testing: Insert the newly cut key into the padlock and verify smooth operation. Adjust cuts as necessary.

Storage and Handling

Store key blanks in a dry, temperature‑controlled environment to prevent corrosion. Keep them away from abrasive surfaces that could damage the delicate keyway profile. When not in use, place blanks in a protective case or labeled container to avoid accidental loss.

Maintenance Tips

• Regularly inspect blanks for signs of wear or deformation.
• Clean with a soft brush and mild solvent if dust accumulates on the keyway.
• Avoid exposing blanks to extreme temperatures, which could alter material properties.

Conclusion

The Key Blank 64179 is a critical component for anyone working with the Draper 30mm Laminated Steel Padlock. Its precise dimensions, robust steel construction, and engineered keyway geometry make it an indispensable tool for creating reliable, custom keys that ensure secure operation of this high‑security padlock.
