EZARC 16PCS Bi-Metal Hole Saw Kit, 3/4"-2-1/2", Cuts Multi-Materials

The EZARC 16-Piece Bi-Metal Hole Saw Kit is a comprehensive drilling set designed to cut clean holes across wood, plastic, drywall, and thin metals. Made for DIYers and trade workers handling everyday installations, it provides the core sizes needed for running pipes, mounting door hardware, recessing lighting, or running cables through desk surfaces.

Durability and speed come from the M42 bi-metal build infused with 8 percent cobalt. This construction allows the teeth to withstand tough jobs while cutting up to 30 percent faster and lasting twice as long as standard saws. The 4/6 TPI variable tooth pitch produces smooth, stable cuts, while all-access ejector slots let chips clear quickly to minimize friction and heat buildup during continuous use.

With a cutting depth of 1.89 inches (48mm), the kit handles 10 standard sizes: 3/4, 7/8, 1, 1-1/8, 1-3/8, 1-1/2, 1-3/4, 2, 2-1/4, and 2-1/2 inches. It comes fully equipped with 3/8-inch and 7/16-inch arbors, pilot drills, an adapter nut, a washer, and a hex key. Everything fits inside a heavy-duty storage case with a secure latch, custom slots, and a clear lid label for quick identification on the job.

As for trade-offs, the cutting capacity is limited to thin metals, so it is not built for thick structural steel. In addition, the maximum cutting depth is 1.89 inches, which may require cutting from both sides if you are working on thicker stock, and the largest included saw diameter is 2-1/2 inches.

Verdict: This set is an excellent choice for woodworkers, plumbers, and homeowners who need a durable, organized hole saw kit for daily installation tasks. It delivers dependable cutting efficiency across multiple materials without needing extra accessories to get started.
