Cutting & Diamond Discs

A diamond disc cuts by grinding, not slicing — diamond grit bonded to a steel rim wears the material away, which is why one blade outlasts a stack of abrasive wheels and cuts hard stuff abrasives can't touch. DMTools diamond discs fit standard angle grinders and cut-off saws (4", 4-1/2", 7" and up) and come in the three rim styles that cover every job: turbo, segmented and continuous-rim. Pick the rim for the material. A segmented rim cuts fast and runs cool through concrete, brick and block — the all-rounder for masons and demo. A turbo rim blends speed with a cleaner edge for harder, denser material and faster dry cutting. A continuous rim gives the smoothest, chip-free edge for tile, porcelain and stone where finish matters — usually run wet to keep the cut cool and dust down. Using the wrong rim is the fastest way to waste a blade and ruin an edge. Diamond is premium tooling sold at honest pricing here — genuine diamond segment on a true-running steel core, without the name-brand surcharge. Buy the single disc your material needs or keep a few rim types on hand so you're ready for concrete one day and tile the next. Collect in Hamilton at 1565 Barton St E on Fridays and Sundays, 10–5, or have your discs shipped Canada-wide. Pickup is free and discs ship flat and light.
