Image to illustrate that some objects are resistant to bolt cutters due to being harder than the metal used in the cutters' blades Some materials which might require cutting are made of hardened steel, which has been tempered (usually heated with other subtances and then rapidly cooled). These materials are usually resistant to bolt cutters.

Angle grinder

Person using an angle grinder to cut off a bolt protruding from a surface An angle grinder can successfully cut through hardened steel because, rather than attempting to slice it, its fast-spinning blade grinds the metal and eventually cuts right through it.

Hand-held rotary cutter

A dremel tool which is a small handheld power device with a small circular cutting head. A hand-held rotary cutter is small and easily-manoeuvrable. It is therefore useful for narrow spaces where an angle grinder cannot fit. It performs the same job as an angle grinder, rapidly filing off tiny flakes of material until it cuts right through.

Diamond or carbide-tipped circular saw

Circular saw blade, the edge of which is coated with tungsten carbide, designed to cut through very hard materials An industrial power saw with a diamond-edged or carbide-tipped blade will cut through hardened steel.
