Cavity Master Technical Specification
The Cavity Master is a precision engineered tool manufactured from high quality materials. The blade is easily replaced and the tungsten carbide rebate cutters are good for many years of service.
The Cavity Master should only be used in conjunction with a 600W or higher rated drill at a medium to fast speed setting. The drill should also feature a side handle.
The 2mm rebate should be covered with the purpose designed closure plate and silicone sealant. Alternatives include a ventilation plate or plasterboard mesh, both made to measure the Cavity Master access hole.
