Description
Overview
Alpha PVAMSK is the PVA MS marble-edge polishing assortment: a ten-disc pack covering five grades for dry finishing. The cushioned silicon-carbide/polyvinyl-alcohol abrasive follows contours and irregular edges and resists clogging during the supported polishing and paint-removal work.
Features
- Color-coded progression from Extra Coarse to Extra Fine.
- For marble edges, baseboards, corners and countertop-edge touch-ups.
- Also useful on stainless steel, glass edges, ceramic edges, wood and other listed metal work.
What's Included
- Ten discs total: two each of Extra Coarse, Coarse, Medium, Fine and Extra Fine.
Specifications
- Model: PVAMSK
- Style: PVA MS
- Disc diameter: 4 inches
- Arbor: 5/8 inch
- Maximum speed: 12,000 RPM
- Use: Dry only
Applications
Use this MS-style kit for marble, limestone, travertine and similar soft-stone edge finishing. It is not the low-speed PVA QC kit or the 4-1/2-inch threaded-hub PVA VP disc.
Selection and Use
- Keep PVA dry; water can make it swell and unsafe to use.
- Do not use PVA for granite polishing. Alpha recommends Ceramica or Ceramica EX for that wet-polishing task.
- Follow the MS mounting arrangement: a reinforcement plate is used with the tool’s adapter flange and retaining lock nut.
- Progress through the grades without skipping; the medium stage is 220 grit.
