We made our long running cuts up both sides of the "V" with an EZ544 Carbide Cutting Wheel. We also recommend adding the Cutting Sheild as we found that cutting PVC can be a messy job!
For this accessory change, pull down the levers of the tool, remove the Multipurpose Accessory. Next, remove the nosecap of the 4200 tool and thread the Shield onto the threaded portion of the tool. Finally, mount the EZ544 accessory onto your EZ Lock Mandrel. Insert the accessory into your tool, set the tool to high speed, and cut along your marked line of cut.
