Mortar Raking Diamond Blades – Pro

A mortar raking diamond blade is one of those tools that looks simple but makes a significant difference when you’re doing it properly. This Pro blade is built for raking out old or damaged mortar joints on brickwork and stonework, giving you a clean, consistent key for repointing. The mortar raking diamond blade features laser-welded premium diamond segments, which means the segments stay put under sustained use rather than separating from the core when things heat up.

The diamond concentration is notably high, which translates directly to faster cutting and a longer working life. You’re not burning through a blade every hour. The cooling slots around the body help dissipate heat as you work, which matters more than people realise — mortar raking is a slow, consistent task, and heat build-up is the main reason blades fail early or glazing becomes an issue.

Where This Mortar Raking Diamond Blade Gets Used

The heavy-duty body gives the blade enough rigidity to handle tough lime mortar, older sand and cement joints, and even some natural stone pointing work. It’s not trying to be a cutting blade — it’s designed specifically to remove mortar at the right depth without damaging the surrounding brick faces. That’s a job that punishes the wrong blade quickly.

Available in 115mm and 125mm sizes, both with a 22mm bore, these blades fit the most common angle grinders on site without needing adaptors. The 8mm segment width gives a clean joint recess suited to standard repointing work. If you’ve ever tried raking joints with a standard cutting disc and wondered why the brickwork looks like it lost a fight, this is the answer.

Blade Construction and Segment Quality

Laser welding is worth highlighting here because it’s the difference between a blade that holds up under repeated use and one that sheds segments mid-job. The weld integrity on a quality mortar raking diamond blade directly affects safety as well as performance. These are manufactured to handle the kind of continuous grinding that repointing work demands, not the occasional light pass. The self-cooling design means you can maintain a reasonable working pace without stopping to let the blade cool every few minutes, which on a long repointing job is genuinely useful.
