Description
Overview
Alpha PVAQCK is a five-pad quick-change assortment for dry edge polishing on low-speed tools. The snail-lock system allows pads to twist on and off the dedicated backer, making it convenient to progress through the five grades.
Features
- Dry polishing without water or finishing wax.
- Quick-change snail-lock connection.
- For low-speed polishing tools, not unrestricted high-speed grinders.
What's Included
- One pad each: Extra Coarse 40 (White), Coarse 80 (Red), Medium 220 (Blue), Fine 400 (Green) and Extra Fine 600 (Yellow).
- PVA-5/8 quick-change backer pad is sold separately.
Specifications
- Model: PVAQCK
- Diameter: 4 inches
- Maximum speed: 4,000 RPM
- Use: Dry only
- Required backer: Alpha PVA-5/8; sold separately
Applications
Use the kit on marble, travertine, onyx and similar soft-stone edges, including shaped or bullnosed profiles. The family also supports stainless-steel polishing, easing glass-tile edges and paint-removal work.
Selection and Use
- Keep the pads dry: Alpha warns that wet PVA can swell and become unsafe to use.
- Work through White 40, Red 80, Blue 220, Green 400 and Yellow 600 without skipping stages.
- Do not use this PVA system for granite polishing; Alpha directs granite work to Ceramica or Ceramica EX wet systems.
