THE Preparation Group has added a new machine to its equipment range specifically designed for hire - the 110v 250SP Single-Head Grinder.
Designed for small commercial and domestic projects, the 250SP has a range of interchangeable diamond accessories for multi-functional use; cleaning and keying all types of surfaces, removing concrete laitance, smoothing and levelling, descaling and removing glue, bituminous adhesives and paint along with wet and dry polishing of hard surfaces.
The guard has a removeable section to enable the disc to prepare and polish right up to vertical edges that are usually inaccessible.
A reportedly unique feature is that the 250SP is said to be suitable for economical wet polishing of hard, previously ground surfaces such as concrete. It has a water pipe port to feed water onto the surface and a range of resin polishing pads from coarse grades to fine. Using the pads wet reportedly enhances the finished polish and increases diamond life.
An adjustment lever lifts and lowers the wheel height for different accessories and to accommodate wearing of the diamond disc.
‘Along with the built-in spirit level, the operator can ensure a level, even connection with the surface and maintain a more aggressive and smoother grind than that achieved by floating head alternatives,’ says the company.
‘The adjustable handle enables a comfortable operating position and folds down for compact transportation and storage. Of steel construction with a powerful motor, yet light and compact, the 250SP offers optimum grinding and polishing performance combined with simplicity and ergonomic design.’
