Abracs General Purpose Diamond Blade 115mm 350mm

The Abracs General Purpose Diamond Blade is a dependable cutting disc for everyday site work. Part of the Abracs Dynamo range, it handles the materials you encounter most often: concrete, brick, block, paving slabs and general masonry. When you need a blade that does the job without overthinking it, this is the one that goes on the grinder.

General purpose blades earn their place in the van because they remove decisions from the equation. You are not swapping discs every time the material changes. Cutting through a concrete lintel, then trimming a few bricks, then notching a paving slab? The same blade handles all three. For mixed-material jobs and general construction cutting, that flexibility matters more than having a specialist blade for each substrate.

Segmented Design for Efficient Cutting

The segmented rim design serves two purposes. First, the gullets between segments clear dust and debris as you cut, preventing the blade from clogging and overheating. Second, they allow air to circulate around the cutting edge, keeping temperatures down during extended use. This matters when you are working through dense materials like concrete, where friction builds quickly.

With a 10mm segment height, these blades offer decent service life before the diamonds wear through. You are not replacing them after a handful of cuts. For a blade at this price point, the balance between longevity and cutting speed is well judged. They cut cleanly without being so aggressive that they become difficult to control.

Size Options for Different Tools

The range covers most common cutting scenarios. The 115mm and 125mm sizes fit standard angle grinders, which is where most tradespeople reach for a diamond blade first. Quick cuts, tight spaces, trimming to fit. The 230mm option suits larger angle grinders for heavier work, while the 300mm and 350mm sizes are designed for petrol cut-off saws and floor saws where you need deeper cuts through slabs, kerbs or thicker concrete sections.

Bore sizes are matched to the equipment: 22mm for the smaller blades used on grinders, 20mm or 25mm for the larger blades on saws. Check your tool’s arbor size before ordering. Most grinders take 22mm as standard, but floor saws vary.

Maximum operating speed is 5100rpm for the 300mm blade. Smaller blades can run faster, larger blades slower. Always match the blade’s rated speed to your tool’s no-load speed. Running a blade above its maximum rating is a good way to have a bad day.

These blades suit dry cutting, which is how most site work happens. Wet cutting extends blade life and reduces dust, but few angle grinder jobs justify setting up a water supply. For occasional cuts and general site work, dry cutting with proper dust management is the practical approach.

The red colour coding identifies these as general purpose blades in the Abracs range. Handy when you have a few different blades rolling around in the same case and need to grab the right one without squinting at specifications.

For the price, the Abracs Dynamo general purpose blade offers solid performance across the range of materials you cut regularly on site. It will not outperform a specialist concrete blade on reinforced sections, or a dedicated brick blade on engineering bricks, but it handles everyday cutting work reliably. Sometimes the best tool is the one that does everything reasonably well.
