Dewalt D180001 Plumber Hole Saw Kit 9 Piece Bi-metal

Product Description

The DEWALT D180001 is a 9-piece bi-metal plumber hole saw kit designed for cutting through metal, pipe surrounds, and rough framing in plumbing rough-in work. The kit includes six hole saws spanning 3/4 inch to 2-1/4 inches in diameter and two mandrels, giving plumbers the core sizes needed for common drain, waste, and supply line penetrations. Bi-metal construction pairs a high-speed steel cutting edge with a flexible steel body, resisting tooth stripout and heat buildup during repeated cuts. The kit stores in an included case, keeping saws and mandrels organized on the job.

This kit is suited for residential and light commercial plumbing rough-in applications where multiple hole sizes are required in a single job. The six individual saw diameters — 3/4 inch, 7/8 inch, 1-1/8 inches, 1-1/2 inches, 1-3/4 inches, and 2-1/4 inches — cover typical copper, CPVC, and PEX supply line pass-throughs as well as standard drain line penetrations. Licensed plumbers and plumbing apprentices working on new construction or remodel projects will find the range of sizes practical for most rough-in scenarios.

Installation Notes

Licensed plumbers typically install hole saws using a corded or cordless drill driver at the appropriate RPM for the saw diameter and material being cut. Always power down and disconnect the drill before changing saw attachments or mandrels. Ensure the mandrel arbor is fully seated and locked before beginning a cut. Follow applicable building codes, including IPC requirements, for pipe penetration sizing and fire-blocking requirements at framing members.
