The MILWAUKEE 1-1/2 in. Spade Bit Attachment w/ RUST GUARD Plating sets a new standard in the market for rust protection, maneuverability, and durability, delivering up to 3X longer life than other drain cleaning cables. Traditional drain cables and attachments will oxidize, causing fragments of steel to erode off the cable, damaging the structural integrity and can lead to rust stains on floors and carpets surrounding the jobsite. Through a proprietary plating process, our RUST GUARD plating delivers 20X more rust resistance, protecting against metal fatigue. This head attachment works with Milwaukee 3/8 in. and 1/2 in. inner core cables and 5/8 in. open wind cables.
