The FIMOR SERILOR Diamond-Fine squeegee edge polisher is a unique, manual tool to enhance the quality of squeegee edges. In most cases, grinding or cutting effectively sharpens a squeegee's worn edges. However, for jobs that require superior image quality, hand polishing is the only method to produce long-lasting, streak-free edges. The 600-grit Diamond-Fine polisher is a fast, consistent, easy way to fine tune squeegee edges for repeatable, high-quality results. (Encore Engineering)
