Description

The HIGHDRIL Diamond Mortar Raking Bit is engineered for precision removal of old mortar, blown brick, and damaged natural stone without compromising adjacent masonry. With an 8mm diameter and 25mm working length, this M14 threaded bit features vacuum brazed diamond technology that delivers faster material removal and reduced vibration compared to standard tungsten cutters. Ideal for both horizontal and vertical joints, the bit excels in delicate restoration work on precious stones and intricate masonry where accuracy matters. The grit 45/50 composition ensures efficient cutting whilst minimising damage to surrounding surfaces. Compatible with angle grinders featuring M14 threads, this tool suits professional contractors preparing surfaces for re-grouting and DIY enthusiasts tackling restoration projects. Use the 25mm bit as a preparation tool before re-grouting or pair it with longer variants for complete brick removal and work behind pipes.

Key Features

Vacuum brazed diamond technology with 45/50 grit provides longer tool life, faster material removal and significantly less vibration than traditional tungsten cutters.

Designed for delicate vertical joints and natural stone work, the diamond mortar raking bit prevents damage to important masonry and precious stones during removal.

Versatile applications include removing old grout before re-grouting, extracting blown or damaged brick, installing ventilation tiles and clearing wall slits.

Suitable for both professional contractors and DIY enthusiasts, the 25mm bit works as preparation for re-grouting or removal projects on various masonry surfaces.
