The 503ETF is a medium-sized, robust precision tip cutter from the Weller Erem Series 500 Micro, featuring an angled wide head for flush cutting. Manufactured from high-grade tool steel, its cutting edges are hardened to Rockwell 63-65 HRC for durability and can be resharpened. This cutter has an overall length of 110 mm and can cut copper wire up to 1.2 mm, medium hard wire up to 0.8 mm, and hard wire up to 0.6 mm in diameter. Being ESD-safe, it prevents damage to sensitive components, making it ideal for microelectronic work where the angled head provides precision at various working angles.
