Compact solution for angles and edges in stainless steel

FEIN has expanded its stainless steel range to include a powerful fillet weld grinder. The flat tool head can quickly and efficiently machine fillet welds on metal constructions without damaging neighbouring surfaces, even in acute angles. The Fein KS 10-38 E fillet weld grinder was developed to meet the requirements of niche metal workers, including specialist interior craftsmen, industrial tank constructors, and ship and vehicle builders. Fillet welds occur automatically when two metal workpieces are welded together at an angle. Metalworkers have to grind these often difficult-to-reach spots, to satisfy customers’ finish and corrosion resistance requirements. Fein has developed a solution for this application. With a head just 33mm long, the powerful fillet weld grinder reaches even very narrow fillet welds. The head can be smoothly swivelled through

180° and fixed to the neck of the machine without the need for tools, which shortens the overall length of the machine and makes even work on corners and work offset to the side possible. The spark hood can be adjusted or removed entirely for different working positions. The grinder features an easy-main- tenance belt tensioning system. The clamping fixture ensures optimum transfer of force and preserves the drive belt, while the patent-pending spindle lock allows fleece discs to be changed easily, without putting strain on the clamping belt. For fast work progress, especially with long fillet welds, the fillet weld grinder features an 800W motor with permanent overload capacity. Double gear reduction delivers a very high torque, and the speed range can be electronically adjusted between 1,350 and 3,750rpm. Even when subjected to continuous use, neither the machine nor the head will overheat, allowing for safe working and avoiding unnecessary interruptions. Fein offers hard-pressed fleece discs with a diameter of 150mm and thicknesses of 3 and 6mm. Coarse fleece discs are suitable for descaling fillet welds and for removing scratches; medium discs smooth and grind fillet welds; fine discs harmonise contours, remove tarnishing and deliver a satin-finish; and very fine fleece discs prepare fillet welds for polishing. Fein can also supply profiling stones, to allow fleece discs to be

With a high plunge depth and rotatable tool head, the grinder can be used on difficult-to-reach spots

given the right profile, and felt discs and polishing pastes. The Fein stainless steel range consists of power tools and accessories tailored to the typical applications involved in machining stainless steel surfaces. It includes angle grinders, polishers and appropriate stainless steel accessory sets for surfaces, pipes, profiles, corners and edges. For grinding and polishing work on pipes and profiles, Fein offers belt grinders and pipe grinders. The Grit range of belt grinders is suitable for grinding in volume production. The Fein fillet weld grinder is supplied in a plastic case with two medium and two fine fleece discs (one 3mm thick, the other 6mm thick) and one profiling stone, and is available from specialist dealers.
