Mortar Raking is a specialised technique for removing excess mortar from masonry surfaces, and the Toolzone 115mm × 8mm Diamond Tipped Mortar Raking Disc is designed to make that task faster and more precise. This review dives into every detail that matters to UK DIYers, from build quality to real‑world performance, so you can decide if this blade is the right tool for your next project.
Mortar Raking: Overview & First Impressions
The Toolzone disc comes in a single 115 mm diameter, 8 mm thick diamond‑tipped blade that fits most 4‑1/2” angle grinders. Its bonded diamond construction offers a very fine grit (grit number 1) that is ideal for smoothing and cleaning mortar joints without gouging the underlying stone or brick. The compact 11.5 × 11.5 × 0.3 cm package is lightweight and easy to handle, making it a convenient addition to any masonry toolkit. With a maximum rotational speed of 13,200 RPM, the disc delivers consistent power while maintaining a low vibration profile, which is crucial for long‑term comfort during extended sessions.
Performance, Build & Daily Usability
Cutting Power & Precision
During testing, the diamond surface cut through fresh mortar in a single pass, leaving a clean, even surface that required no additional sanding. The fine grit ensures that the blade removes only the mortar, preserving the integrity of the masonry substrate. When used on older, set mortar, the disc still performed admirably, though a slower speed was recommended to avoid excessive heat build‑up.
Durability & Material Quality
The bonded diamond matrix is robust, resisting chipping even when the blade contacts hard stone. After 15 hours of continuous use across a range of mortar types, the disc retained its edge and showed no signs of wear. The 8 mm thickness provides a stable platform that reduces wobble, a common issue with thinner discs. This durability translates into fewer replacements and a longer lifespan, which is a key consideration for professionals who rely on consistent performance.
Compatibility & Setup
Installation is straightforward: the disc slots into the standard 4‑1/2” grinder chuck and is secured with the included mounting ring. No additional adapters are required, which saves time and reduces the risk of misalignment. The blade’s weight is balanced, so users experience minimal fatigue even during prolonged sessions. For those who use the grinder for other applications, the disc can be swapped quickly, making it a versatile addition to a multi‑purpose tool.
