Editor's Note
This editor’s note highlights the key facts and market implications behind “Nozar: Landscape Construction Professionals Test”, with emphasis on sourcing, product fit, fabrication, logistics, or buyer impact.
Cutting ceramic slabs, removing reinforcements, cutting through plastic, bitumen, hard rubber, sheet metal, or capping tree roots – cutting blades are indispensable in landscape construction (GaLaBau). Two professionals have now tested various cutting blades from Nozar, including all-rounders and specialists. "The most universal cutting blade for landscape construction," agree landscape contractors Ralf Gruber from Meppen and Hermann Pohlabeln from Lorup in Lower Saxony, referring to the 'Spezial' diamond cutting blade. Available in diameters from 115mm to 400mm for angle grinders, cut-off grinders, and table saws, it cuts almost all materials such as clinker bricks, composite pavers, concrete, brick, natural stone, sand-lime brick, or granite. For a fast cut, it is equipped with short-tooth segments and for better heat and dust dissipation with a perforated core.
“It is fast-cutting, durable, and can be guided cleanly even over a longer cutting distance,” emphasizes Managing Director Ralf Gruber. “For years now, this has been the diamond cutting blade par excellence in our company, after we previously tested blades from various suppliers.”
Chip-Free Cutting of Ceramic Slabs
In addition to established materials, a new trend material is increasingly coming to the fore in landscape construction: ceramic. Because the slabs and composite slabs are dimensionally stable and relatively light, they are easy to install. For cutting, due to the contained mixture of clay, sand, quartz, and feldspar, a special cutting blade like the Gres Ultra S2 from Nozar is required. Hermann Pohlabeln uses this diamond blade for wet cutting on a table saw.
“It cuts chip-free and clean edges on hard ceramic, ceramic patio slabs, as well as composite slabs with 4-6 cm concrete base and adhesive,” Pohlabeln concludes.
Gruber has had the same experience with ceramic patio slabs: "Perfect cut, clean cut edge, very good cutting speed." This is ensured by both the extremely aggressive segments and the continuous core. In addition to ceramic slabs and composite slabs, this diamond blade (Ø 230, 300 and 350) is also suitable for wet cutting glazed tiles, thin granite, and for miter cuts on large-format porcelain stoneware tiles. For dry cuts, Pohlabeln uses the smaller sister for the angle grinder: the Red Devil Fliese (Ø 115, 125 and 230).
“It cuts quickly, absolutely cleanly, and with remarkably low vibration thanks to flange reinforcement,” he says.
Landscape contractor Gruber uses the Red Devil Fliese for cutting material up to 2 cm thick: "Super fast, very precise cut edge, and despite a normal core, very quiet." For drilling holes, e.g., for spotlights, in ceramic, porcelain stoneware, and thin granite, Nozar offers the M14 tile drill for dry use, suitable for all common angle grinders from 10,000 RPM, and for adjusting holes, pin routers for concrete and granite.
REDSUN Relies on Nozar Cutting, Grinding, and Drilling Technology
At REDSUN, a leading European trader of natural stone and ceramics as well as a producer of concrete paving stones, sidewalk slabs, curbstones, palisades, stair treads, etc., Nozar's diamond tools have also proven themselves.
“We are very pleased to have found a cooperation partner in Nozar that has the right cutting, grinding, and drilling technology for processing our materials in its range,” says Dominique Münch, Sales Manager at REDSUN.
Sound-Damped Blade Reduces Noise Level
An issue when cutting mineral materials is always noise reduction. It is prescribed for construction measures, especially in city centers, residential areas, and near public facilities. For work in public spaces, Gruber and Pohlabeln use the noise-reduced cutting blade Twin Matrix with Nozar Silentcut on a cutting table or angle grinder – one of the quietest blades in its segment. The multi-layer sandwich core (SDW) reduces noise development by about 15 dB; the edge area with alternating matrix diamond and turbo segments ensures fast cutting through different stone types from granite to sand-lime brick as well as general building materials.
“The sound-damped cutting blade is indispensable. Not only because it is already required by some architects, but also because it spares the nerves of neighboring residents and significantly reduces the noise exposure for my employees,” says Pohlabeln.
Doesn’t Bite the Grass on Roots
For cutting through railway sleepers or hardwood including nails and screws, capping tree roots, or cutting plastic, bitumen, roofing felt, hard rubber, and sheet metal, the two landscape construction professionals swear by the carbide-tipped cutting blade Nozar Rip Cut for all common angle grinders and gasoline cut-off saws.
“It’s better than a chainsaw,” judges Gruber, “and really gets to work.”
For Pohlabeln, the Nozar Rip Cut is a problem solver when he has to remove old tree remains in awkward corners of the garden.
“Then I mount the cutting blade on a cut-off saw and can easily reach the farthest corner.”
