4-1/8” Deep HSS Bi Metal Hole Saw Cutter with Arbor Cutting Depth

The PLG2SUPT 4-1/8-inch Bi-Metal Hole Saw is built for DIYers and tradespeople who need to cut clean, wide openings in everyday construction materials. It provides a cutting depth of up to 1-1/2 inches (38 mm), making it suitable for standard boards, panels, and thin sheet metals. The package includes the hole saw cup, a chuck mandrel, and two distinct pilot drill bits.

Material versatility is a key focus for this tool. It cuts through wood, plasterboard, PVC, MDF, drywall, and aluminum. The bi-metal strip is manufactured with laser welding and vacuum heat treatment to improve tooth hardness and overall strength. To match the job at hand, you receive a silver HSS bit for wood and soft metals, plus a black HSS bit tailored for harder metals.

For metalworking, the cutter can drill up to 30 holes in 0.12-inch low carbon steel plate. Users must manage their drill speed carefully, especially at the start, as operating at high speeds initially can easily break the teeth. Additionally, the tool ships in either red or black, with color selection handled at random.

Verdict: The PLG2SUPT 4-1/8-inch hole saw is a capable choice for anyone cutting large openings in drywall, timber, plastics, or thin metal sheets. It offers solid cutting capability as long as you maintain lower drill speeds during initial contact.
