About This Product

Dry Sanding and Polishing for Edge Treatments

Alpha Dry Sanding/Polishing Kit transforms a compatible variable-speed angle grinder or polisher into a 4" dry edge-finishing system. It gives fabricators a practical way to sand and polish edges using an existing power tool while adding a coordinated dust-collection setup.

Vacuum-Connected Dust Control

The 4" dust guard surrounds the working area while the universal hose connects the assembly to a vacuum. This configuration pulls dust away from the surface during dry sanding and polishing, helping create a more controlled edge-treatment process.

Adaptable Variable-Speed Tool Conversion

Included collars, hose bands, flanges, and mounting accessories allow the system to fit compatible Makita grinders, Alpha 800 Series polishers, and many popular 4-1/2", 5", and 6" variable-speed angle grinders. The design also supports straightforward installation and convenient disc changes.

Common Questions

Frequently Asked Questions

What does the Alpha Dry Sanding/Polishing Kit do?

The kit converts a compatible variable-speed grinder or polisher into a 4" dry sanding and polishing system for edge treatments. Its dust guard and hose components connect the working area to a vacuum so dust can be pulled away during operation.

Which grinders and polishers are compatible?

Alpha lists compatibility with Makita grinders and Alpha 800 Series polishers and states that the kit fits most popular 4-1/2", 5", and 6" variable-speed angle grinders. Because tool housings and collar dimensions vary, confirm the specific model against Alpha's compatibility information before ordering.

Does the dry sanding kit require a vacuum?

Yes. Alpha specifies that the dry kit must be used with a vacuum. The universal dust hose and connection components are included, but a vacuum is not part of SPD4KIT. Alpha also offers a separate package pairing the kit with its HEPA1035 vacuum.

What components are included with SPD4KIT?

The kit includes a 4" dust guard, hose holder, two stainless steel hose bands, hose connector, plastic and stainless steel collars, T9.0 spacer, inner flange, lock nut, universal dust hose, P30 pin wrench, and 3-foot memory wrap.

Are the power tool and sanding discs included?

No power tool, vacuum, or sanding and polishing discs are listed with SPD4KIT. The kit supplies the dust-control and mounting components used to convert a compatible tool. Select suitable 4" dry accessories whose speed ratings match the intended application and equipment.

Does this kit support wet and dry polishing?

SPD4KIT is the dry version and uses vacuum extraction to collect dust. It is not a combined wet and dry system. Alpha sells the SPW4KIT separately for wet sanding and polishing applications that require a water hose and water-control components.

What is the maximum operating speed?

The Alpha Dry Sanding/Polishing Kit has a maximum operating speed of 6,000 RPM and is designed for 4" sanding and polishing accessories. The connected power tool must provide variable-speed control and remain within the speed rating of the kit and selected accessory.
