Weller Erem - Craftsmanship of the highest quality. Weller Erem side and end cutters are offered for a variety of different applications. The special tool steel is hardened using a unique Swiss manufacturing technique. Thanks to a patented Magic Spring, the spring force in Weller Erem cutters and pliers is guaranteed to remain constant for at least 1 million closing cycles. The Weller Erem cut provides a smooth cut without overlapping jaws, thanks to a special screw system in the cutting head. For optimal results, Weller Erem offers three possible cutting shapes as well as specially hand-ground cutting edges. Exceptional longevity is ensured due to a very high hardness level (Rockwell hardness scale 63–65 HRc). There are no signs of hand fatigue. The EMOS opening stop limits the opening and thus facilitates work. All Weller Erem cutters and pliers are ESD-safe. The jaws are ground with the highest precision. Ergonomically shaped handles provide high comfort, grip, and safety.
