This 7-piece set of Proxxon MicroSpeeder combination ratchet spanners comes in a steel case with a moulded insert. The spanners have a slender and long design. The compact and very slender heads allow them to work in tight spaces. The ratchet features an inner gear ring with 72 teeth meaning it is still effective with only 5° of movement. The chrome vanadium steel shaft undergoes double nickel-plating followed by matt-finished chrome plating for guaranteed long life. Durable laser marking means permanent easy-to-read sizes. Designed for professional use with a 2-year guarantee. The set comprises sizes 8, 10, 13, 16, 17, 18 and 19 mm in a sturdy steel powder-coated box.
