No generation of hazardous and explosive dusts. Can be used on angle grinders Ø4.5” and Ø5” An excellent alternative to abrasive grinding discs and flap discs. Mounting hole 22.2mm Very high stock removal rate with reliable controllability at the same time. No adhesion due to polished chip guide surfaces (construction cutting edge). The HW cutting elements are extremely durable and rotatable and replaceable. CNC machined from a single piece of high-strength aluminum. Due to the defined cutting geometry, there is no dust, just chips. As a result, a potential health and explosion hazard is reduced to an absolute minimum compared to the grinding process. The safest, most effective and most economical solution for manual processing of aluminum. Use: For machining aluminium alloys on one-handed angle grinders 115-125mm. The field of application is cross-industry in container, shipbuilding and vehicle construction as well as in the aluminium casting sector. The most common application is the pre- and post processing of weld seams, the milling of root seams and the coarse machining of castings. Machinable materials: aluminium alloys, copper, zinc as well as wood and plastics (also fibre composites).
