Type 27 Aluminum Flap Discs

The 4 1/2″ Type 27 Aluminum Flap Discs are known as the ultimate solution for cutting and grinding aluminum. Their innovative paired flap design allows for high-performance grinding, making them perfect for a variety of applications. The top flaps are specifically coated to eliminate loading, enabling the disc to maintain a high cut-rate throughout its use. The alternating positions of the flaps contribute to a more aggressive material removal process, thanks to the self-sharpening zirconia aluminum grains.

These Type 27 aluminum flap discs are designed to be used at a 0-15 degree angle, making them especially effective for grinding flat surfaces and outside corners. The 36-grit option is ideal for tasks like beveling, chamfering, weld removal, and general stock removal, while the 60-grit choice is perfect for blending welds, finishing, and achieving a polished look.

With a maximum RPM of 13,000 and compatibility with angle grinders, these discs are a robust addition to any toolbox. Continental Abrasives guarantees the quality of their products, promising satisfaction and support for any concerns you may have. Their commitment to using high-quality raw materials, including virgin grain and durable resins, ensures that these flap discs deliver world-class performance for all your grinding projects.

Operating instructions:

• Select the correct flap disc type and grit for your material and application.
• Inspect the flap disc for cracks, tears, broken flaps, or other visible damage before use.
• Ensure the grinder’s maximum RPM does not exceed the maximum RPM listed on the flap disc.
• Disconnect the power source before installing the flap disc.
• Mount the disc securely on the grinder, using the correct flanges and ensuring proper centering.
• Tighten the disc according to the manufacturer’s instructions.
• Test run the grinder at full speed in a safe area for at least 60 seconds before applying to the workpiece. Avoid standing in the disc’s direct path during this time.
• Hold the grinder at a 15°–25° angle to the surface for optimal grinding and flap wear.
• Use light, consistent pressure and move the tool in smooth strokes across the surface.
• Do not force the flap disc into the material; let the abrasive do the work.
• Avoid prolonged grinding in one spot to prevent overheating and rapid flap wear.
• Allow the grinder and disc to come to a complete stop before setting it down or changing discs.

Handling:

• Store flap discs in their original packaging in a dry, cool place away from moisture and sunlight.
• Avoid stacking heavy objects on top of flap discs to prevent warping or damaged flaps.
• Handle discs carefully to avoid impacts or drops that could cause hidden damage.
• Always check for any signs of warping, cracks, or loose flaps before use.
• Keep discs flat during storage and prevent contact with oils, solvents, or corrosive substances.

Safety information:

• Always wear ANSI-approved eye protection, hearing protection, gloves, and a dust mask or respirator suitable for the material being ground.
• Use only with properly installed and functioning safety guards on your grinder.
• Ensure the workspace is clean, dry, and free of flammable materials. Keep bystanders at a safe distance.
• Never exceed the recommended RPM for the installed flap disc.
• Do not use flap discs for side grinding or for applications other than their intended use.
• Replace the disc immediately if you notice excessive vibration, noise, wear, or visible damage during operation.
• Follow all manufacturer and tool safety instructions and dispose of used or damaged flap discs according to local regulations.
