Nupla is a US manufacturer of premium non-sparking hand tools, specialising in hammers, mallets, and striking tools constructed with fibreglass and composite handles engineered to resist breakage, vibration, and chemical exposure. Their non-sparking and non-magnetic tool range is designed for use in explosive atmospheres, flammable environments, and areas where metal striking tools present an ignition hazard, including petrochemical, mining, and defence applications.Nupla handle setting compound is a two-part epoxy system for permanently bonding replacement tool handles into hammer, axe, and sledge heads. The compound fills the eye of the tool head completely, eliminating voids that cause handle loosening under impact, and cures to a rigid bond that resists the shock loads generated during heavy striking work.Where this product is usedHandle setting compound is used wherever tool handles are being replaced or secured: Workshops and maintenance facilities where handle replacement on hammers and axes is part of the planned maintenance schedule. Sites where loose hammer heads on fibreglass or wooden handles present a safety hazard. Industrial environments where the bond strength and chemical resistance of epoxy is required over traditional wood wedge systems. Selecting the right optionThe setting compound is the correct product for bonding Nupla fibreglass handles into tool heads — the epoxy formulation is specifically designed to bond to composite materials. Apply to a clean, dry tool eye and handle taper, allow full cure time before use. Do not use setting compound as a substitute for structural adhesives in applications beyond tool handle fitment.
