The Malco Turbo-X Tool Quarter Panel Hemming Attachment (QHT1) gives you the ability to bend and close wheel arc flanges of replacement quarter panels. Simply attach it to your cordless drill or impact driver for easy one-hand operation. A telescoping clamp adjusts to fit both the length and width of your drill or impact driver. This tool replicates a hammer and dolly motion at high speed, giving you greater precision and faster results. A rubber cushioned anvil protects your quarter panel from scratches and scuffs. The long-wearing anvil and hammer are replaceable and can be installed easily while you're on the job.
