G-Tec grinding cowls attach to angle grinders using an aluminium clamp, machined to be an exact fit for specific models. This is very important as the rubbing action of the polyurethane shroud on rough or uneven surfaces could easily unseat a poorly attached cowl. The moulded polyurethane shroud is flexible in construction, thereby accomodating reducing height of the grinding disk (through wear) and the uneven nature of many surfaces. Moreover, when the shroud has worn away, the aluminium clamping boss can be unscrewed and a replacement shroud can be fitted.

G-Tec cowls are supplied with custom flange nuts which position a standard format diamond grinding disk optimally within the shroud. These flange nuts are supplied in appropriate sizes for both 125mm and 180mm grinders. By exception, Hitachi 180mm cowls are configured to use the manufacturer supplied flange nuts and hence are a less expensive item.

All G-Tec cowls are supplied with a detachable polyurethane hose cuff. This cuff permits use of either 50mm or 38mm diameter vacuum hose. It ensures maximum vacuum effect is retained by sealing closely with the shroud. It also stops the hose end fraying or losing shape and permits its easy removal and replacement.

The G-Tec hose outlet is parallel to the grinding surface and in line with the natural draft created by the rotating disk, thereby maximising the dust extraction potential.

An SV50 dust extractor is suitable for use with a grinder fitted with a 180 mm G-Tec dust cowl and a diamond 'cup' disk
