Product Information

Full details

The Starchem DA Pad (DAV-6) is a professional-grade backing pad designed for automotive technicians and industrial fabricators who require reliable performance during surface preparation and sanding tasks. Its primary benefit is the 6-hole dust extraction design, which effectively clears debris to ensure a smoother finish and longer abrasive life; however, users should ensure their sander’s vacuum pattern matches this 6-hole configuration to achieve optimal dust management.

FAQs

Is this pad compatible with all 150mm sanders?

It is compatible with most 150mm dual-action sanders that utilize a standard bolt-on or thread-on spindle, provided the hole pattern aligns.

Can I use this with PSA (Pressure Sensitive Adhesive) discs?

No, this pad is designed exclusively for HookIt (Velcro-style) discs.

How do I know when the pad needs replacing?

The pad should be replaced if the hook material no longer holds discs securely or if the foam edge begins to crack or deform.

Does the 6-hole pattern fit a standard multi-hole vacuum system?

It fits most standard 6-hole vacuum setups; however, it is best to verify your specific sander's hole configuration before purchase.

Should I use lubricant on the pad?

No, never apply lubricants, solvents, or cleaners to the backing pad, as these can damage the adhesive and the hook material.

Troubleshooting

Abrasive disc slipping during use

Check if the hook surface is clogged with dust or worn out; clean with a brush or replace the pad.

Excessive vibration during operation

Ensure the pad is perfectly centered on the sander spindle and check for any debris trapped between the pad and the tool.

Poor dust extraction

Verify that the 6 holes in the pad are aligned correctly with the holes in your sanding disc and the vacuum path of the machine.

Pros and Cons

Pros

  • Efficient dust extraction keeps work surfaces clean
  • HookIt system enables fast, reliable disc changes
  • Consistent weight and balance reduce vibration
  • Durable build quality for heavy-duty industrial use

Cons

  • Requires specific 6-hole alignment for full dust extraction efficiency
  • Not compatible with non-HookIt sanding discs
  • Must verify sander backing plate diameter matches 150mm requirement

Setup, Compatibility & Care

To set up the pad, ensure the sander is disconnected from the power source or air supply. Align the center hole and the dust extraction ports of the DAV-6 pad with the spindle and vacuum holes on your dual-action sander, then tighten securely according to the manufacturer's torque specifications. The pad is compatible with all 150mm HookIt-style abrasive discs. To maintain the pad, avoid using high-pressure air to clean the hook backing, as this can degrade the grip material; instead, use a soft-bristled brush to remove any residual sanding dust. Periodically inspect the hook surface for signs of wear or melted fibers, which may indicate it is time to replace the pad.
