Keeping your work area clean while drilling is difficult, so the Klein Folding Ring Saw Dust Collector for circular saws up to 6-3/8“ diameter and mandrels up to 1/2” diameter comes to the rescue. Its two-piece design provides the support you require by holding debris in place throughout the process. It is made of thermoplastic elastomer and polypropylene, which provide flexibility and durability. The dust collector has a friction connection that fits the three most common vacuum hose sizes: 32mm, 48mm and 64mm. It makes it easy to connect and clean the dust bowl on site. The attachment can be easily folded up and does not interfere with drilling with the circular saw.
